YCM error. The ycmd server SHUT DOWN (restart wit...the instructions in the documentation

Question

I installed YCM with vim plug, but I may have shut down before process finished. Now when I start vim I get this error "The ycmd server SHUT DOWN (restart wit...the instructions in the documentation."

I've googled but can not find workable solution. I don't see anything in the documentation that helps. But I am new to vim and coding in general so may be missing something.

:YcmDebugInfo comes back with "Server errored, no debug info from server".

I have tried :YcmRestartServer, but to no result -- it pauses then returns the same error. I have also run :PlugInstall and :PlugUpdate, and all plug ins, including YCM, are coming back as up to date.

it would be greatly helpful if you also give the log or debug info along with OS and other environment details. – Feudist

Answer 1

I ran into the same issue with Vundle and fixed it like this:
After installing cmake, I cd'd into ~.vim/bundle/YouCompleteMe and ran python install.py

Busman

I couldn't run it but after I installed python-devel packages then it works fine thanks. – Rosaleerosaleen

This fails on vim 8.2. Cmake seems to be expecting an olde r Python version and exits with an error. – Newsome

Answer 2

I was also facing the same problem with vim and I am using vim-plug plugin manager. To overcome this I did this:

cd ~/.vim/plugged/youcompleteme
python3 install.py

Done !!!

I use Vundle so for me it was cd ~/.vim/bundle/YouCompleteMe – Weakkneed

Answer 3

Another problem that may cause that error is conda, you should run install.py from the python's system and not the conda one, to do that use

/usr/bin/python ./install.py

from the youcompleteme folder inside vim

Quite similarly pyenv introduce shims which when invoking the python binary rely on static Python library instead of dynamic ones. Solution is to use the system Python with /usr/bin/python as suggested by Mike in his answer. – Virgule

Thanks, this worked for me in 2023 -- had the same issue with Anaconda. – Papaveraceous

Answer 4

I was also facing the same issue but I have solved by executing the following commands in the Ubuntu terminal

cd ~/.vim/bundle/YouCompleteMe/
sudo pip install cmake
python install.py

or

cd ~/.vim/bundle/YouCompleteMe/
sudo pip3 install cmake
python3 install.py

Exact

Thanks. I used your code with one modification:sudo pip3 install cmake. In most system, pip3 is used along with python3. – Girard

thanks for your update. when i have used at that time pip was working but now in new systems comes with pip3 as default. thanks for your comment – Exact

Here is how I have solved Mac OS Catalina 10.15.3 python 3.7 vim 8.2

Install ycm with 'Vim-plug' using Plug 'ycm-core/YouCompleteMe'

1. cd ~/.vim/plugged/YouCompleteMe
2. brew install cmake
3. python ./install.py

Answer 6

2023:

• macOS Monterey
• Anaconda
• Python installed with homebrew

Had to :

cd ~/.vim/bundle/YouCompleteMe/
# DONT use conda python in the following install step
/opt/homebrew/bin/python3 ./install.py

Papaveraceous

I was in the same situation. this helped. – Kallick

Answer 7

$ cd ~/.vim/plugged/youcompleteme
$ bash install.sh
(or)
$ python3 install.py

It will only work if you have installed the python3.7 version

Glorification

you may add some explanation that how this code is the answer of the question. – Myogenic

Answer 8

Here is how I did this recently with following environments

Mac OS Mojave 10.14.3

Vim 8.1.300

Python 3.7

Java version 1.8.0_40

$vim --version | grep python
+comments          +libcall           -python            +viminfo
+conceal           +linebreak         +python3           +vreplace

Installed ycm with Vundle using Plugin 'Valloric/YouCompleteMe' and then running :PluginInstall

The plugins in downloaded to ~/.vim/bundle/YouCompleteMe

$cd  ~/.vim/bundle/YouCompleteMe
$python3 installer.py --java-completer

This creates appropriate files under /.vim/bundle/YouCompleteMe/third_party/ycmd/third_party/eclipse.jdt.ls (make sure these and inner directories are not owned by root unless you always work as a root)

now open vim and execute :YcmRestartServer

You should be good to go.

Try :YcmDebugInfo to check if everything is fine

CentOS Linux release 7.6.1810 (Core)

Vim 8.1.1362

Python 3.7.3

Java openjdk version "1.8.0_191"

Overall process remains same, but I had couple of difficulties on Centos

• Vim was not compiled with Python support

sudo vi /etc/ld.so.conf

added /usr/local/lib to it which had libpython3.7m.so.1.0 file

sudo ldconfig
git clone https://github.com/vim/vim.git
cd vim
./configure --prefix=/usr/local/ --enable-python3interp=yes --with-python3-command=/usr/local/bin/python --with-python3-config-dir=

Rest of the procedure remains the same.

I had a very similar issue and fixed it today. Here's what I've done

• Install YCM's requirement in vundle

  cd ~/.vim/bundle/YouCompleteMe; python3 install.py

• Reproduce the problem, then check its log in vi mode. The error I had reads

  Traceback (most recent call last): File ImportAndCheckCore ycm_core = Import Core() File /.vim/bundle/YouCompleteMe/third_party/ycmd/ycmd/utils.py", line 493, in ImportCore import ycm_core as ycm_core ImportError: ~/miniconda3/lib/libstdc++.so.6: version 'GLIBCXX_3.4.30' not found

• Check whether libstdc++.so.6 contains GLIBCXX_3.4.30, but receive GLIBCXX_3.4.2x which apparently doesn't satisfy the dependency

  strings ~/miniconda3/lib/libstdc++.so.6 | grep GLIBCXX_3.4.30
  GLIBCXX_3.4.2x
  

• Then seek the correct libstdc++.so.6 that contains the expected GLIBCXX_3.4.30

  sudo find /usr -type f -name "libstdc++.so.6*"
  /usr/lib64/libstdc++.so.6.0.30
  
  strings /usr/lib64/libstdc++.so.6.0.30 | grep GLIBCXX_3.4.30
  GLIBCXX_3.4.30
  

• Copy /usr/lib64/libstdc++.so.6.0.30 and create a softlink to ~/miniconda3/lib/libstdc++.so.6

On 6.1.31-1-MANJARO, the same problem got fixed after running cd ~/.vim/bundle/YouCompleteMe; python3 install.py
