Re: [Pydev-users] Help please: Python, Mac, Eclipse, PyDev

[Fabio Z. <fa...@gm...>]

The links for dropbox didn't appear, so, it's hard to know what's
going on... so, I'm guessing here: mac doesn't provide the .py files
for the library, so, you have to either use the interpreter from
python.org or grab the .py files from the library and copy them to
your mac installation (personally, I always use the version from
python.org instead of using the one from the system -- you never know
what you may break in the system while developing).

If that's not the case, try entering the links in the forum (not sure
why the links didn't appear properly in the e-mail).

Cheers,

Fabio

[Pydev-users] Help please: Python, Mac, Eclipse, PyDev

[Torvon <to...@gm...>]

Hey there.

(1) My employer forces me to work on a MAC, that's a new OS to me. So excuse
me if these questions are stupid. (10.6.8)

(2) I have eclipse, and want to run Python in it. I followed the steps
installing PyDev, no problemo. Now I have to setup the path where the
interpreter is in. And I can't find it. I found 10.000 topics on the net for
this problem, but none solved my issues.

(3) Most of the topics say check /libraries/Python. In this folder I have 3
subfolders, called 2.3, 2.5 and 2.6. These folders contain identical things:
a folder called "site-packages", which contains a readme, which contains
("This directory exists so that 3rd party packages can be installed here.
Read the source for site.py for more details.")
Nothing else.
The PyDev stuff is apparently in my /repast-simphony/eclipse/plugins folder
(in this folder are 5 subfolders called PyDev 2.2.1 etc blablabla and then
debug/fastparser/analysis etc.)

Ok. So how do I find where my Python actually is?
I tried --> python -c "from distutils.sysconfig import get_python_lib; print
get_python_lib()"
which tells me
--> /Library/Python/2.6/site-packages

But that is empty.

In /system/frameworks there is one. That one looks interesting. But no
matter if I choose "Python" (alias, no idea what that means on mac, but it
looks like an executable file) in the main folder, or the other Pythons in
subfolders (e.g. versions/2.6 or versions/current), I receive an unspecific
error which is kind enough to tell me that common problems are using an
unsupported version or specifying an invalid interpreter.

python -c "import sys; print sys.executable"
... points to the folder /usr/bin/python.
(there are also other ones like python 2.6 in that folder)

In eclipse now I enter this path as interpreter, like that:
http://dl.dropbox.com/u/35594260/Bildsc ... .18.31.png

I get this message dialog afterwards (I don't understand this, because this
is EXACTLY the dialog that appears if I do not enter the path manually "new
->", like above, but when I hit "auto config):
http://dl.dropbox.com/u/35594260/Bildsc ... .18.38.png

When I click OK, this error message pops up:
http://dl.dropbox.com/u/35594260/Bildsc ... .18.44.png

I honestly have no idea what to do. Please help.

Thanks
Eiko

I have the same issue.. Is a option to turn off it?

I want to deploy a test version to user and not provide the source code, the

to get the latest version, they know about the svn, but not has any idea of
Python.
So, I don't want to package the scripts to egg file, the pyc files are the best

You said it worked, but in the 2nd place it's the same print from the first
(is that right?)

Also, you need actual python modules (i.e.: files that can be imported) as the
test files, so, if you had only 'test' and not 'test.py', it's expected that
it wouldn't work.

Also, your files need to be in the pythonpath... have you followed the steps
from: http://pydev.org/manual_101_root.html to configure pydev?

Hi, 

I'm new to linux, eclipse and python. I'm using Mint 11, I installed python
3.2 from synaptic, eclipse 3.5.2 from the software manager and installed pydev
from within eclipse. I have added the python 3.2 interpreter as usr/bin/python3.2
(but it was automatically changed to python3.2mu) and it added five folders
to the libraries tab. Python 2.7 is also there, but I didn't add it manually.

When I tried a hello world program, it didn't do anything: 

Finding files... done.
Importing test modules ... done.

----------------------------------------------------------------------
Ran 0 tests in 0.000s

OK

So I renamed the file from "test" to "test.py" and it worked: 

Finding files... done.
Importing test modules ... hello
done.

----------------------------------------------------------------------
Ran 0 tests in 0.000s

OK

I ran a line of code to print the version of python and it is 3.2. However there
is no code highlighting or code completion. Is this normal or am I missing steps
to configure pydev?

[Pydev-users] [Users] RE: Remote Debugging and Remote System Explorer

The following forum message was posted by mpietrek at http://sourceforge.net/projects/pydev/forums/forum/293649/topic/4641556:

Thanks Fabio. I appreciate the answer.

The important thing is that I now know what' possible or not possible so that
I can stop banging my head against this particular wall.

As I'm understanding it, Remote System Explorer (RSE) seems to be the defacto
default way of interacting with remote systems. As such, I was hoping there'd
be at least some minimal awareness, especially since PyDev supports remote
debugging.

It sounds from your response that most people develop their project locally,
and then when they need to deploy, push the sources to the remote box and fire
up remote debugging as necessary. In this case it would make sense that you'd
have two source trees kept in sync.

I guess I'm spoiled coming from the Microsoft remote debugging world. There,
they have the notion of the "source server". When the debugger can't find a
source file it asks the server for it, and if returned by the server, the debugger
caches it locally. Timestamps and other tricks keep everything up to date. The
end result is that remote debugging  is very seamless if configured properly.

I'll fill feature requests for RSE support.

Thanks,

Matt

The following forum message was posted by fabioz at http://sourceforge.net/projects/pydev/forums/forum/293649/topic/4641556:

Hi there, first let me say that I haven't actually used the remote system explorer
myself, so, I may be wrong on some answer -- but I do know PyDev pretty well :)

For the remote debugging, the way it's implemented right now, you do need to
have access to sources locally. I guess this could be done better if it knew
you're in the remote system explorer, but right now PyDev knows nothing about
this (so, you do need sources locally) -- so, unfortunately, right now, the
best advice I can give you is using pdb in this situation :(

I think PyDev could be improved so that the debugger asks for the source to
the remote backend if it can't find it (please open a feature request for that).

As for the 2nd question, the same goes here, as PyDev is oblivious of the remote
system explorer, it can't launch it (although maybe you could ask to the remote
system explorer guys if they have a way to make it work).

Cheers,

Fabio

The following forum message was posted by mpietrek at http://sourceforge.net/projects/pydev/forums/forum/293649/topic/4641556:

Hey all,

I'm a relatively new Pydev user, just starting a few months back. I'm looking
for some validation on whether I'm on the right track here. My scenario:

I've got some Linux servers running in VMs. These servers have various python
projects that I need to edit/debug, etc... Ordinarily I'd just run Eclipse/Pydev
locally and life would be good. However, when working from home via VPN, X-Windows
is completely unusable - The latency is just too high.

To remedy this, I've installed Eclipse/Pydev on my workstation (Mac OS Snow
Leopard). I've also installed the Remote System Explorer Plugin and using the
SSH connector can see and edit projects remotely on the Linux VMs. So far, so
good.

However, remote debugging on the Linux systems has proved to be more or a challenge.
I understand and accept that I need to add a reference and use pydevd from my
source. I've had some limited success in that I can see in my Mac Eclipse instance
that the process has debug-attached, and that I can step/run the remote app
- just not with source debugging. Each time I step, the Eclipse debugger indicates
that it can't find the source file. Thus the first question:

1) How do I get the Eclipse debugger to point at the remote machine sources?
I can obviously see and edit these sources via RSE, it's just that the debugger
seems unaware of them. I've noticed that there's a Pydev "Debug | source locater"
dialog, but it implies that the sources are in both locations. I don't have
the source locally - They're only on the remote system. What's the preferred
way of working with this situation?

Question 2: When starting/restarting a new process instance for debugging, is
there a way to launch the python app *easily* from within the IDE, or do I need
to switch to a shell on the remote machine and launch it manually?

Thanks much for any help. I've searched long and hard for answers and while
I see some related answers, none seem to address my specific questions.

Since I updated PyDev the Code analysis shows error on valid Python lines like
def (a, *b):

It breaks on parsing the "*" saying "Expected :)" . Actually it doesn't always
do that and copy-pasting the same text into a new file may not show an error
in the new file. The program works.

Moreover PyDev started complaining about "from a import b" (Unresolved import)
where "b" actually does really exist and the Python program runs fine.

I tried refreshing the projects, but I don't know what else to try.

Any suggestions?

Having been two days with this problem, I solved it in less than an

In my computer this problem was resolved doing this:

$ ln -s _sqlite3.cpython-32mu.so _sqlite3.so #as superuser or sudo'ed

Another way: (seems a workaround to me, but not sure)
adding _sqlite3 to the forced built-in list.

Thanks, and I hope it's useful for somebody.

[Pydev-users] Import problem with sqlite3

[Alex B. <ale...@gm...>]

Hello, it was a while since I last used PyDev and now I see that it's
so much better!

I was checking some already working code I had and have a problem with
sqlite3. I'm on a Ubuntu 11.04 and python3.2. Running Eclipse 3.5.2
with PyDev 2.2.1

PyDev says "Undefined variable from import: connect" when I do a
harmless sqlite3.connect
The program works fine, simply that messages appear there and it's
very annoying (provided that it's an *Error*, not a warning...)

If I use the same code for python2.7 then PyDev do not complain. Works
fine in both versions.

The path and folders are the same in both Python configurations (some
/usr/lib/python* and some /usr/local/lib/python*).

Somebody has the same problem? I haven't tried it in other systems or
python/eclipse configurations (yet).
