[sumo-user] Netconvert command and Error: Cannot import network data without PROJ-Library

[mima L. <dja...@gm...>]

Hello SUMO-users

I have please a small question about NETCONVERT command

I want to map-match a GPS dataset so and according to my previous posts you
advice me to use use SUMOpy

To do that I have first to have the ".net.xml" network file, I have the OSM
file of the area

So I have to convert OSM file to .net.xml

I have written

* netconvert --osm Desktop/Beijing.osm*

But I get this error

Error: Cannot import network data without PROJ-Library. Please install
packages proj before building sumo Quitting (on error).

I try to install  PROJ-Library with this command

sudo apt-get install libproj-dev

but I still get the same error and even I tried the following commands

sudo apt-get install libproj-java
sudo apt-get install libproj9
sudo apt-get install proj
sudo apt-get install proj-data

but I always see that the packages are installed with newest version

such as the following

Reading package lists... Done
Building dependency tree
Reading state information... Done
proj-bin is already the newest version.
0 upgraded, 0 newly installed, 0 to remove and 426 not upgraded.


I really don't know what to do in order to resolve this problem and get
".net.xml" file from OSM file

Thank you in advance for any help in this topic

Best regards
