syntastic: error: checker python/python returned abnormal status 1

[baif666]

When I use syntastic I meet this problem

Flake8 found issues
syntastic: error: checker output:
Traceback (most recent call last):

IOError: [Errno 2] No such file or directory: ''
syntastic: error: checker python/python returned abnormal status 1

Could anyone help me solve this problem?

Please open your test file, set g:syntastic_debug to 33, run :SyntasticCheck python, run :mes, and post the output. Please use cut & paste rather than screenshots.

I run :mes after :SyntasticCheck python

Thanks for your answer

I'm having the same issue. The output per your request is

@mattamizer Unless you did set syntastic_python_python_fname to an empty string, this looks like a Neovim issue. As I said elsewhere, syntastic should work with Neovim, but that combination is not supported. Can you reproduce the problem with plain Vim? Can you reproduce it with all other plugins disabled?

[mattamizer]

It is reproducible with plain VIM:

With all plugins save syntastic disabled everything seems to work fine, so I think this issue can safely be closed. I'll dig and figure out what the conflict is. Thanks!

EDIT: Seems the conflict was with the vim-flake8 plugin. Removing that plugin has fixed the errors for both nvim and vim.

[lcd047]

@mattamizer You could try something like binary search to isolate the conflicting plugin. It's always useful to understand how and why these problems happen.

[mattamizer]

I edited my comment above but I'll add the same here for clarity; the conflict was with vim-flake8. Not really sure why I had that installed as well as syntastic but there you have it. Thanks for the assistance @lcd047!

[lcd047]

@mattamizer There seem to be several plugins named vim-flake8. Which one did you have installed?

[mattamizer]

@lcd047 nvie/vim-flake8

[lcd047]

@mattamizer Looking at the sources it seems vim-flake8 shouldn't be incompatible with syntastic, provided that you don't run both at the same time. So you could in principle either remove the autocmd on BufWritePost for vim-flake8, or configure syntastic_mode_map to be passive for python. But syntastic has a flake8 checker, so there doesn't seem to be much point in running both vim-flake8 and syntastic against the same file anyway.

On the other hand, detecting autocmd conflicts like this is not possible because of limitations of Vim's API, so syntastic couldn't really do anything better here. That's just about all there is to it, I think.
