Problem with MacVim #254

Closed ssbanerje closed 10 years ago

ssbanerje commented 11 years ago

I am trying to use powerline with MacVim (from homebrew). I had successfully got it working about a month (or more) ago. However I just pulled the latest changes a few days ago and I get this error - 

Error detected while processing function Powerline:
line    3:
E858: Eval did not return a valid python object

I have cloned powerline to ~/.powerline and run ./setup.py build && ./setup.py install --user (on the master branch) And the relevant portions of my vimrc file are -

"Powerline {
    set rtp+=~/.powerline/powerline/bindings/vim
    set laststatus=2 " Always display the statusline in all windows
    set noshowmode
    if has('gui_running')
        if has("gui_gtk2")
            set guifont=Monaco\ for\ Powerline\ 10
        else
                set guifont=Monaco\ for\ Powerline:h12
        endif
    else
        set t_Co=256
    endif
"}

However, I am also using the very same steps on my Linux box, and it seems to be working fine.

This is the stacktrace --

Probably related to #180

After the commits in the last few hours, the problem seems partially resolved.

When I launch MacVim from the GUI icon. Powerline seems to work properly!

However, I am getting some very weird behaviour, when I launch the editor from the terminal (either as vim or mvim), I get the same error.

I am attacting a screenshot.

I am attacting a screenshot.

Attach right screenshot. “Eval did not return a valid python object” is not informative. It is strange you need to be told this twice, after you successfully posted required text.

Also post :scriptnames output here. It looks like if you are using powerline.vim from the wrong powerline version (assuming that problem is actually the same and you just attached wrong screeshots, but had tested using right methods).

ssbanerje commented 11 years ago

The screenshot and error are the same. I am still getting the same error --

Error detected while processing function Powerline..<SNR>94_pyeval:
line    1:

line    1:

However, if I dont run it with the debug flags (g:powerline_debugging_pyeval=1), I get this (as in the sceenshot) -

Error detected while processing function Powerline:
line    3:
E858: Eval did not return a valid python object

As for the version, I am using the powerline.vim file which comes along with 3c62e06

:scriptnames output from both cases, where error is shown and where it is not. I am suspecting you run different powerline.vim versions. Though I am likely false and you actually run different powerline versions somehow.

ZyX-I commented 11 years ago

To check for powerline location use

py import powerline as pl;print pl.__file__
ssbanerje commented 11 years ago

The output is /Users/Subho/Library/Python/2.7/lib/python/site-packages/Powerline-beta-py2.7.eg g/powerline/__init__.pyc

ZyX-I commented 11 years ago

@subszero In both cases? I do not care about your powerline location, I need the answer whether this location is the same for both failing and not failing case. Same for :scriptnames.

ssbanerje commented 11 years ago

Ya... Its the same in both cases

ZyX-I commented 11 years ago

Your powerline.vim script is located in ~/.powerline/powerline/bindings/vim/plugin/powerline.vim, but actually used powerline is located in another directory. Fix this. If you installed via pip remove powerline and reinstall using

pip install --user -e ~/.powerline
