#664 problem while installing PyTango 8.1.1 with pip (using pip 1.4.1)

[Zbigniew Reszela]

I encountered a tiny problem while installing PyTango with pip (easy_install seems to work without problems).

I'm not sure if it's a problem with my environment or a PyTango "bug".

I use the following command to install it:

pip install PyTango --egg

(I need to use --egg, otherwise I get an exception)

Well actually package seems to get installed correctly:

pc255:~ # pip show PyTango
---
Name: PyTango
Version: 8.1.1
Location: /usr/lib64/python2.7/site-packages
Requires:

However at the end of installation I get:

(...)

copying /tmp/pip_build_root/PyTango/build/sphinx/html/_static/basic.css -> /usr/share/doc/PyTango/html/_static

Hi Zbigniew,

Sorry to take so much time to answer.

If the exception resulting from not using --egg is:
error: option --single-version-externally-managed not recognized
then the solution seems to be either (from stackoverflow):

1. use --egg
2. upgrade setuptools

Regarding the errors: they both seem to be inside python 2.7 distutils.
The first is a call to get_outputs which doesn't seem to exist.
The second is during the clean up due to the first error.

Can you try to install/upgrade setuptools and try without --egg?

Thanks in advance

Seems that it is not related with PyTango.
I will close this ticket
