Installation Problem

[ghost]

I installed completor.vim with vim-plug as follows:

Plug 'maralla/completor.vim'
let g:completor_python_binary = '/home/dai/anaconda3/bin/python'
let g:completor_filetype_map = {'python.django': 'python'}

But the following error occured while editing python files.

I checked the log.

I have searched online, didn't find a solution. Any help is appreciated.

Could you please run the command :messages in you vim after the Error detected while processing function... error happened and post the result here?

@maralla Thank you for your reply.

The above is the first screen, the same error messages are repeated till the end of :messages.

[maralla]

Run this command in your terminal:

$ vim -c ":py import completor;print('ok')" -c "qall" -T dumb

and check whether ok is shown.

[ghost]

Nope, it said ImportError: No module named completor. Because of my python version? I'm using python anaconda version, but I have pointed that python binary.

[maralla]

Run vim and execute the command scriptnames to check the existence of <plug path>/completor.vim/plugin/completor.vim. If the plugin is missing, the installation of completor is failed. If not ls the content of <plug path>/completor.vim/pythonx and post the result.

[ghost]

@maralla Thank you for your reply. <plug-path>/completor.vim/plugin/completor.vim exists. I tried $ vim -c ":py import completor;print('ok')" -c "qall" -T dumb again. It gave me 'ok'. I listed the directories in <plug path>/completor.vim/pythonx. It gave me two directories, completers and completor. However, I still get the following error when i edit a python file;

Error detected while processing function <lambda>1[1]..completor#do[7]..completor#utils#get_completer:

The error is saying completor module not found and completor_api is not defined. I think somehow the installation is not successful with vim-plug. Is the completor module going to be installed in the python path? Or it's not okay with the other plugins I have installed. I have no idea. Please have a look when you have a little spare time. At the same time, I'm going to experiment your pack and see it works with pack installation. Thank you very much for your time. P.S: I'm on Solus GNU/Linux. I'm not sure it is the reason.

[maralla]

Could you please disable (comment out) all plugins except completor to see whether the problem still exists?

[ghost]

Yes, the problem still exists although I have disabled all plugins. I want to try pack, it looks cool and clean. I'll get back to you. Just for the reference, from :messages,

@maralla Hi Wei Zhang, I found the problem. It is because of python anaconda distribution. I removed anaconda. Now completor is working like charm. By the way, I like pack too. Thank you for that. My vimrc will be a lot cleaner. Let me close the issue.
