Issue Details

Provide a clear description of the problem, including the following key
questions:

• What did you do?

Include steps to reproduce here.

1. Do a fresh install of YCM on my system via Vundle, as per the README. ./install.py completes with no errors. I used --clang-completer and --rust-completer. This completed without errors.

2. Open a C or Rust file in Vim.

3. Almost immediately, I get the following message:

The ycmd server SHUT DOWN (restart with ':YcmRestartServer'). Unexpected exit code 1. Type ':YcmToggleLogs ycmd_41096_stderr_g94lju2q.log' to check the logs.

Include description of a minimal test case, including any actual code required
to reproduce the issue.

Open any C or Rust file (I have tried a few)...

• What did you expect to happen?

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

• What actually happened?

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

Include link to a gist containing the invocation and entire output of
install.py if reporting an installation issue.

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...

[micbou]

Thanks for the report. If the ycmd logfiles are empties, this means that the server crashed before redirecting its standard streams to the logfiles. You should try to start ycmd manually. Run these commands in a terminal:

cd ~/.vim/bundle/YouCompleteMe/third/ycmd
cp ycmd/default_settings.json .
python ycmd --options_file default_settings.json

and paste the output.

[mark-i-m]

@micbou Thanks for your response... Is there some dependency on a particular version of OpenSSL?

[micbou]

Seems related to issue https://github.com/Valloric/YouCompleteMe/issues/2765. Could you try the suggestion in that comment?

sudo apt purge python-openssl
sudo apt install python-openssl

[mark-i-m]

Hey! That worked 🎉

Thanks @micbou!

[micbou]

Happy to help.

[DShivansh]

@mark-i-m
in this same situation i am getting
can't find '__main__' module in 'ycmd'

[DShivansh]

please help

[puremourning]

@DShivansh please see CONTRIBUTING.md

[mark-i-m]

@DShivansh I wish I could help, but I am not really that familiar with the internals of YCM... I just followed the suggestion in the post above.

[puremourning]

can't find 'main' module in 'ycmd'
in this same situation i am getting

No, they are totally different and unrelated. @DShivansh make sure that you have run git submodule update --init --recursive and that you're using python 2.7.2 or later (or python 3.4.0 or later)

[kirykr]

worked for me: Just run /usr/bin/python install.py in ~/.vim/plugged/YouCompleteMe

[idopshik]

I've spent one hour trying to resolve and finally found it. Thanks kirykr

[rednatto]

For me the an issue looking like the original issue (on opening rust file) was due to having a corrupt PYTHONPATH set. After unsetting it I could run the ycmd without issue!

[yanchina]

in this same situation , i find in third_party/waitress/waitress/server.py at line 206，then function self.socketmod.gethostbyaddr(server_name)[0] is run error if your computer name contains Chinese characters

[Peppershaker]

had anaconda installed and using python3 install.py worked for me

[supr3m3]

$ cd ~/.vim/bundle/YouComepleteMe
$ /usr/bin/python install.py

[alclol]

For me the an issue looking like the original issue (on opening rust file) was due to having a corrupt PYTHONPATH set. After unsetting it I could run the ycmd without issue!

Could you please elaborate on how to set PYTHONPATH for ycmd to work? I had no problem with using python elsewhere but not able to get away with the server shut down error with YCM

[DirtySoc]

I also ran into this issue. To fix it I had to:

$ sudo apt install cmake
$ cd ~/.vim/bundle/YouComepleteMe
$ python3 install.py
