YouCompleteMe unavailable: No JSON object could be decoded #2413

Closed yanyan33333 closed 7 years ago

yanyan33333 commented 7 years ago

I installed YCM successfully ,but when I start vim the info show YouCompleteMe unavailable: No JSON object could be decoded My .vimrc setting

let g:ycm_global_ycm_extra_conf = '$HOME/.vim/bundle/YouCompleteMe/third_party/ycmd/cpp/ycm/.ycm_extra_conf.py' let g:ycm_collect_identifiers_from_tags_files = 1 let g:ycm_seed_identifiers_with_syntax = 1 set completeopt-=preview let g:ycm_confirm_extra_conf=1 let g:ycm_cache_omnifunc=0 let g:ycm_complete_in_comments=1 let g:ycm_min_num_of_chars_for_completion=1 let g:ycm_use_ultisnips_completer=0 let g:ycm_collect_identifiers_from_tags_files=1
let g:ycm_min_num_of_chars_for_completion=2 let g:ycm_cache_omnifunc=0 let g:ycm_seed_identifiers_with_syntax=1

Maybe something wrong with .ycm_extra_conf.py? but I didn`t modify anything I read from vim :messages

the code is 

def DefaultOptions(): 
    settings_path = os.path.join(
        os.path.dirname( os.path.abspath( __file__ ) ), 'default_settings.json' )
    options = json.loads( ReadFile( settings_path )                                                                     
    options.pop( 'hmac_secret', None )
    return options

but the file default_settings.json I found is JSON format

micbou commented 7 years ago

Thanks for the report. Do you get the same error when trying to load the default_settings.json file in the Python interpreter?

>>> import json
>>> json.loads( open( 'default_settings.json' ).read() )
yanyan33333 commented 7 years ago

No,it runs no error

micbou commented 7 years ago

Does the error still occur when starting Vim with the following minimal vimrc

set nocompatible

set rtp+=~/.vim/bundle/YouCompleteMe

filetype plugin indent on

?

yanyan33333 commented 7 years ago

No,it doesn`t work My python version is 2.7.12 I do some test in here

def DefaultOptions():
    settings_path = os.path.join(                  
        os.path.dirname( os.path.abspath( __file__ ) ), 'default_settings.json' )
    ### test #####
    f = ReadFile( settings_path )
    pprint.pprint(f)  
    #f = f.encode('utf8')
    #pprint.pprint(f)
    options = json.loads(f )
    pprint.pprint(options)
    #### test end ######
    #options = json.loads( ReadFile( settings_path ))
    options.pop( 'hmac_secret', None )
    return options

when I encode to utf8 like

def DefaultOptions():   
    settings_path = os.path.join(       
        os.path.dirname( os.path.abspath( __file__ ) ), 'default_settings.json' )

    print("########## utf8 ##############")

    pprint.pprint(f)
    options = json.loads(f )
    print("########## json ##############")

    pprint.pprint(options)
    #### test end ######
    #options = json.loads( ReadFile( settings_path ))
    options.pop( 'hmac_secret', None )
    return options

the json.loads works but occur other error , output in vim :messages

micbou commented 7 years ago

I don't understand why json.loads is inserting all these null characters \x00 in the result.

Using simplejson instead of json could help debug further the issue. Could you install it with pip (pip install simplejson) then change the DefaultOptions function to:

def DefaultOptions(): 
    settings_path = os.path.join(
        os.path.dirname( os.path.abspath( __file__ ) ), 'default_settings.json' )
    import simplejson
    options = simplejson.loads( ReadFile( settings_path )                                                                     
    options.pop( 'hmac_secret', None )
    return options

and try again?

yanyan33333 commented 7 years ago

I try it again but still not working I need to encode the string to utf8 but other error ocurred

def DefaultOptions(): 
    settings_path = os.path.join(
        os.path.dirname( os.path.abspath( __file__ ) ), 'default_settings.json' )
    import simplejson
    options = simplejson.loads( ReadFile( settings_path ).encode('utf8') )

Maybe something wrong with my python env??

micbou commented 7 years ago

Did you build yourself Python? Could you try with system Python? And you forgot to mention your OS and your Vim version (vim --version).

It`s a long story you know ......... The default glibc version of CentOS6.5 is 2.12.x, which not supported by YCM, so I build a chaintools env with high version glibc (2.21.x) following the LFS . In other words I build almost everything , so far eveything runs well expect YCM..... Maybe something wrong with the python I built, I will revert the code and try again Thanks your helping @micbou

vheon commented 7 years ago

@yanyan33333 I would recommend http://linuxbrew.sh/ instead of doing it by hand, I use it for building YCM and other tools on a RHEL 6 without problems.

micbou commented 7 years ago

The default glibc version of CentOS6.5 is 2.12.x, which not supported by YCM, so I build a chaintools env with high version glibc (2.21.x) following the LFS .

Did you try with Devtoolset installed?

yanyan33333 commented 7 years ago

thank you @vheon I will try it later

yanyan33333 commented 7 years ago

not yet@micbou ,can it run on glibc 2.12.x after install by devtoolset?

puremourning commented 7 years ago

The default glibc version of CentOS6.5 is 2.12.x, which not supported by YCM

If centos 6.5 is the same as RedHat 6.5. then YCM works fine. I use it every day...

vheon commented 7 years ago

@puremourning I believe that it works fine because you have the devtoolset-2 RHEL 6.5 without the devtoolset-2 is not compatible with the libclang binaries that we use on linux

puremourning commented 7 years ago

devtoolset changes the libc version ._0 ? blinks I should look into that :).

I don't use the stock libclangs because of deus ex firewall, so you could be right. :p

yanyan33333 commented 7 years ago

Thanks guys I solved the problem. I run the booting script python __main__.py --options_file ./default_settings.json in ~/.vim/bundle/YouCompleteMe/thirdparty/ycmd/ycmd The script runs successfully , it turns out that the python env is no problem but the using vim I built depends on lower version of glibc(2.12.x),so I rebuild vim with the same glibc version(2.21.x) of python and YCM. Finally, YCM runs no problem I think it`s some strange compat problems on different version of glibc After all , thank you very much ^^
