Issue Details

• What did you do?

Do a fresh install of YCM on my system via Vundle, as per the README. ./install.py completes with no errors. This completed without errors.

But when i start vi. I came out an error.

• What did you expect to happen?

I expected to see no error messages and be able to get completions.

• What actually happened?

The ycmd server SHUT DOWN (restart with ':YcmRestartServer'). Unexpected exit code -11.

I got the error message posted above pretty much immediately after starting vim, with no user interaction required to cause it.

Output of build/install commands

I didn't have any issues with building/installing, so I didn't save the output. But I can rerun ./install.py and post the output if you want

[bstaletic]

Does :py print('foo') or :py3 print('foo') work?

[liuli1735]

@bstaletic yeah, it can print foo, my default python environment is python 3.6 with anaconda.

[bstaletic]

There's an FAQ entry about Anaconda. So just build YCM outside Anaconda environment.

[mandeep]

I'm seeing this same error after upgrading YCM but my Python install is in a virtualenv using --system-site-packages. I built YCM outside of the virtualenv as well as inside but the error hasn't gone away. Both of the print commands @bstaletic gave work as well.

[bstaletic]

Does PYTHON_USED_DURING_BUILDING have an expected value?

[mandeep]

It looks like this error was resolved by installing again in the virtualenvs. Another plugin I updated had acted up as well which made it harder for me to debug everything.
