compiled with python2 support the keyword await but python3 can't? #2852

Closed nullscc closed 6 years ago

nullscc commented 6 years ago

platform: mac os x 10.13

for some reason, i must use python2 and python3 on same machine, so i installed two vim, the only different is the python support.

one vim:

hoodeMacBook-Pro:~ null$ vim --version | grep python
+comments          +libcall           -python            +vreplace
+conceal           +linebreak         +python3           +wildignore

the other:

hoodeMacBook-Pro:~ null$ vim2 --version | grep python
+comments          +libcall           +python            +vreplace
+conceal           +linebreak         -python3           +wildignore

and then i compiled ycm use the two python version defferent:

# for python2, i use
python install.py

# for python3, i use
python3 install.py 

and then, the corresponding .vimrc:

if has('python')
    Plugin 'Valloric/YouCompleteMe'
endif

if has('python3')
    Plugin 'nullscc/PCompleteMe'
endif

if has('python3')
    let g:ycm_python_binary_path = '/Library/Frameworks/Python.framework/Versions/3.6/bin/python3'
    let g:ycm_global_ycm_extra_conf = "~/.vim/bundle/PCompleteMe/third_party/ycmd/examples/.ycm_extra_conf.py"
endif
if has('python')
    let g:ycm_python_binary_path = '/usr/bin/python'
    let g:ycm_global_ycm_extra_conf = "~/.vim/bundle/YouCompleteMe/third_party/ycmd/examples/.ycm_extra_conf.py"
endif

function! PyImports()
Py << EOF

import os.path
import sys
import vim
if 'VIRTUA_ENV' in os.environ:
  project_base_dir = os.environ['VIRTUAL_ENV']
  sys.path.insert(0, project_base_dir)
  activate_this = os.path.join(project_base_dir,'bin/activate_this.py')
  execfile(activate_this, dict(__file__=activate_this))
EOF
endfunction

if has('python')
  command! -nargs=* Py python <args>
  call PyImports()
elseif has('python3')
  command! -nargs=* Py python3 <args>
  call PyImports()
endif

ok, every thing is fine, but the only bad thing is when i use vim(with python3 support) it just can't GoToDefinitionElseDeclaration with the following sample code:

return await self.fetch(request)

what werid is when using vim2(with python2 support) it just work as expect.

micbou commented 6 years ago

Could you give the full code of your example and the position of the cursor where you are running the GoTo command (GoToDefinitionElseDeclaration is deprecated in favor of GoTo)? This way we can try to reproduce your issue with Python 3. Also, could you paste the contents of the :YcmDebugInfo command and attach the ycmd and JediHTTP logfiles (use the :YcmToggleLogs command to open the logfiles in Vim)?

aquatix commented 6 years ago

Just noticed that there's an L missing in your config: if 'VIRTUA_ENV' in os.environ: Not sure if it's related, but it might break things :)

nullscc commented 6 years ago

@aquatix thanks for your reminding. for it's just work as my expect,i don't take notice of it. but i change it like this

function! PyImports()
Py << EOF

import os.path
import sys
import vim
if 'VIRTUAL_ENV' in os.environ:
  project_base_dir = os.environ['VIRTUAL_ENV']
  sys.path.insert(0, project_base_dir)
  activate_this = os.path.join(project_base_dir,'bin/activate_this.py')
  try:
    execfile(activate_this, dict(__file__=activate_this))
  except:
    exec(open(activate_this, encoding = 'utf-8').read(), dict(__file__=activate_this))
EOF
endfunction

it remains not ok for await keywords of GoTo command. so i guess the problem is not the VIRTUAL_ENV. thanks for your reply anyway.

nullscc commented 6 years ago

@micbou ,thanks for your reply, after i put the following code into .vimrc

let g:ycm_log_level = 'debug'

the output of :YcmDebugInfo:

it seems like the problem is the ycm client can't connect to ycm server? and how can i solve the problem?

micbou commented 6 years ago

Thanks for all that info.

it seems like the problem is the ycm client can't connect to ycm server?

These errors occur because the server is not ready yet. That's not the problem here. The issue is that Jedi (the semantic engine used by YCM for Python) returns an error when trying to jump to the fetch method in your example:

This is the same issue as https://github.com/davidhalter/jedi/issues/797 and it's apparently fixed in the latest version of Jedi. So, we need to update Jedi. See PR https://github.com/Valloric/ycmd/pull/888.

micbou commented 6 years ago

Keeping it open until we update ycmd submodule.

nullscc commented 6 years ago

@micbou the issue of jedi i have see it already. i just guess it has update already. so what i can do now is just waiting ycmd submodule to be updated?

micbou commented 6 years ago

Yes. If you don't want to wait, go to the ~/.vim/bundle/YouCompleteMe/third_party/ycmd folder and run the commands:

git checkout master
git pull
git submodule update --init --recursive
puremourning commented 6 years ago

Probably git fetch origin; git checkout origin/master ?

micbou commented 6 years ago

Right. I edited my comment.

nullscc commented 6 years ago

@micbou wow, it just worked, thanks very much.
