Developer install - ImportError: cannot import name NetworkManager, introspection typelib not found

[michaelmcandrew]

Hello there,

I'm trying to get a development environment set up to write a small plugin.

Installing from master on ubuntu 15,04 and following the instructions here: https://github.com/getting-things-gnome/gtg I get to this instruction.

RUN: In order to run GTG from this Developers repository, you need to launch the debug.sh script:

$ ./gtg.sh

But I get an error.

10:29:24 michael@xps13:~/gtg$ ./gtg.sh 
Setting XDG vars to use default dataset.
Traceback (most recent call last):
  File "<frozen importlib._bootstrap>", line 2158, in _find_spec
AttributeError: 'DynamicImporter' object has no attribute 'find_spec'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "./GTG/gtg", line 62, in <module>
    from GTG.gtk.manager import Manager
  File "/home/michael/gtg/GTG/gtk/manager.py", line 26, in <module>

  File "/usr/lib/python3/dist-packages/gi/importer.py", line 53, in find_module
    'introspection typelib not found' % namespace)
ImportError: cannot import name NetworkManager, introspection typelib not found

Am I missing a step?

Thanks!

You may need to install the gobject-introspection and gir1.2-gtk3.0 packages as well as gir1.2-networkmanager-1.0.

I'm getting the same error, but can't find those packages in Fedora 31. Is there any way to try gtg with a current fedora?

Hi @diegogangl you can use the Flatpak package mentioned in #210 (comment) for now (at least until we bring things back in order)...

I suspect this would have been fixed by @ploum's commit 83324a8 ? Reopen otherwise.

I'm getting the same error with master, except in my case it is "NM" instead of "NetworkManager", and line 133 instead of 53:

File "/usr/lib64/python3.7/site-packages/gi/importer.py", line 133, in load_module 'introspection typelib not found' % namespace)
ImportError: cannot import name NM, introspection typelib not found

Trying to build it on Fedora Silverblue 31 inside a Fedora Toolbox container. I've installed python-pip3, the requirements.txt dependencies, python3-pyxdg, python3-dbus, and python3-gobject in the container, all of which were necessary to get past other errors. I am unsure how to deal with this error.

[JaneSmith]

Sorry for the spam. I managed to solve it by installing NetworkManager-libnm-devel. In case it helps anyone else, here is a full list of steps to get a development environment set up on Fedora Silverblue / Fedora Toolbox.

To create a development environment:

git clone https://github.com/getting-things-gnome/gtg.git ~/Projects/gtg
toolbox create -c gtg
toolbox enter -c gtg
sudo dnf install python-pip3 python3-pyxdg python3-dbus python3-gobject NetworkManager-libnm-devel
cd ~/Projects/gtg
pip3 install -r requirements.txt
exit

To enter the development environment and run the software:

toolbox enter -c gtg
cd ~/Projects/gtg
./gtg.sh

To exit the development environment:

exit

To discard the development environment:

toolbox rm -f gtg
rm -r ~/Projects/gtg

Thank you Jane! I'll try to remember to integrate your findings into the scattered developer documentation/instructions/etc. as I review those to see if I can make it easier for people to get started for contributing (ticket #200).
