System Info

Distributor ID: Ubuntu
Description:    Ubuntu 16.04 LTS
Release:    16.04
Codename:   xenial

I cloned the repo and installed by running python3 install.py. I also tried setting let g:ycm_server_python_interpreter = '/usr/bin/python3'. I also tried using python2 to compile and setting the value. But none of the combinations work.

I get the below error

YouCompleteMe unavailable: This package should not be accessible on Python 3. Either you are trying to run from the python-future src folder or your installation of python-future is corrupted.

What is the output of the command:

:py3 import pprint; pprint.pprint( sys.path )

in Vim?

[daniel-dsouza]

I am (unfortunately) able to duplicate this issue.

There is something wrong with your Python path. Those two paths:

/home/dadsouza/catkin_ws/devel/lib/python2.7/dist-packages
/opt/ros/kinetic/lib/python2.7/dist-packages

should not be in sys.path on Python 3. Could you check that they are not defined in your PYTHONPATH environment variable?

[daniel-dsouza]

$ echo $PYTHONPATH
/home/dadsouza/catkin_ws/devel/lib/python2.7/dist-packages:/opt/ros/kinetic/lib/python2.7/dist-packages

They are defined there. I am pretty sure that they are required for ROS though, as python in ROS is primarily 2.7.

[nikhilkalige]

@daniel-dsouza I don't have my pc to check the path, but I think I may have the problem as you, as I am a ROS user like you..:)

[daniel-dsouza]

it seems that ROS adds those paths to the PYTHONPATH, as I don't remember doing it.

since sys.path concatenates PYTHONPATH along with other sources, it seems that that is the source of the problem.

I guess the conclusion is that this is a ROS issue, and not a YCM issue. I am not very experienced with managing multiple python configurations, but is there a way we can use virtualenv, or is there a simpler solution?

In the short term, I might try recompiling vim with the python vs the python3 flag

UPDATE: recompiling vim with python (not python3) support fixes the problem.

[puremourning]

As this is an error with your configuration/environment and not a YCM bug, I'm closing this.

[DXist]

I'm reproducing the same issue on Ubuntu 16.04 when I run Vim inside python2 virtualenv. There is vim-nox-py2 vim version that works in such configuration.

[mraxilus]

Same as DXist here, but I'd very much like to use Python 3 or at least disable that message from popping up.

[Kwpolska]

I’m having the same issue on OS X with MacVim (installed with brew install macvim --with-python3). The error pops up when using any virtualenv.

[micbou]

I am reopening the issue as it seems to affect a lot of users and because I think we can prevent it by improving the way we are adding the python-future module to sys.path. For everyone having the error, could you paste the output of the command:

:py3 import pprint; pprint.pprint( sys.path )

in Vim?

@Kwpolska @mraxilus @radzak Thanks, that's really helpful. I've sent PR https://github.com/Valloric/ycmd/pull/578 that should fix the issue. Feel free to try it out.

[mraxilus]

Thanks, that fixes the issue. I just had to update the submodules using git submodule update --remote --merge.

[roachsinai]

I get same error on a virtual python environment created by virtualenv, today.

YouCompleteMe unavailable: This package should not be accessible on Python 3. Either you are trying to run from the python
-future src folder or your installation of python-future is corrupted.

Casue Ycm unavailable, I can't use YcmToggleLogs command, etc.

Have tried use /home/roach/.vim/plugged/YouCompleteMe/install.py --clang-completer --system-libclang on virtual env get same error.

[micbou]

@roachsinai This should be fixed by PR #3285. Could you give it a try and report back?

[remusao]

@micbou I seem to have the same issue reported here and tried with your PR, and I think it did not solve the issue. At least the symptoms are still present. Does anyone know what caused the issue to appear again all of a sudden? It was working fine for me until very recently, I'm not sure if I updated something and it caused a breakage, but I was surprised.

[micbou]

@remusao I made a mistake in the PR. Could you try again?

It looks like one of these two might have triggered the issue: 1e37efe648e86378d026131f327c0321a891b561 or c209cdbbfcc90c9ab8fa078beb2fe668743b4d0e. If I use this commit b0f18804f3c85eab6bb2912ee3f2f3d2b238404a, things seem to work as usual.

It's commit https://github.com/Valloric/YouCompleteMe/commit/1e37efe648e86378d026131f327c0321a891b561 for sure.

After merge the pull request now, the error is corrected. @micbou thank you very much.

I was just about to post here the same issue, but then noticed the last commit, updated YCM, and the issue seems to be fixed. Great work guys! :)
