[Sicks3c]

Hello

I'm using Kali Os in virtualbox

I get this weird error

Hi @amiralkizaru ,

Can you, please, do $ vim --version and post output here?

Thanks,
Roman

There might be two reasons why this issue appears:

• either your vim does not support Python 3;
• or you are using Python2 as an interpreter.

Does vim support Python 3?

To check this, run vim --version | grep python, and you should see something like:

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

Meaning Python3 but no Python 2 support. As of 2020, this seems to be the outcome of most vim binaries provided by various package managers.

Is your Python interpreter Python 3?

As of 2020, Python2 is the default interpreter on most Linux distros. Vim, however, requires a Python3 environment.
You can check this by running python --version:

$ python --version
Python 2.7.15+

If you use conda or similar Python installations, make sure to call the system's default, and not your shell's (eg. /usr/bin/python)

If indeed your interpreter is Python2, check that you have Python3 available:

$ python3 --version
Python 3.7.6

If so, you're set to resolve the issue by changing the vimrc, lines 154 and 155 to:

" python executables for different plugins                                                                                                                           
let g:pymode_python='python3'
let g:syntastic_python_python_exec='python3'

You should then be set :)

I'm not sure what the Python is on various systems, so I'm not sure whether to open a PR to fix these lines.

@cydanil

Hi, I set vimrc as you suggested. But I still met the problem. My error message is

Exit code: 1
Error detected while processing BufEnter Autocommands for "*.py"..function tagbar#autoopen[9]..<SNR>116_IsValidFile:
line   29:
E121: Undefined variable: s:known_types
E116: Invalid arguments for function has_key(s:known_types, a:ftype)

Do you know the reason?

My OS is MacOS Big Sur and my vim version is

+comments          +libcall           -python            +visual
+conceal           +linebreak         +python3           +visualextra

Thanks!
