Cannot install plugins on Windows

[sryze]

I installed Vim 8.0 on Windows 10 but can't get vundle to install the plugins listed in .vimrc, each time I run :PluginInstall I get this error:

C:\Program' is not recognized as an internal or external command,

and a lot of other errors, but I think this is the main one.

Vim was installed to C:\Vim.

@sryze can you post a minimal vimrc ?

Have you looked into the Windows Setup?

@sryze I'm experiencing this with current 64 bit nightly VIM - Vi IMproved 8.0 (2016 Sep 12, compiled Apr 23 2017 22:02:16:

I have bundle/Vundle.Vim and bundle/YouCompleteMe folders, I do not have a bundle/vim-go folder. Vundle.vim folder contains up-to-date clone of this repo. I have manually deleted some folders from bundle/ while trying to start my config fresh. But now I'm stuck because I can't find where Vundle.Vim is storing the state.

:PluginList shows Vundle.Vim and vim-go. I have tried running :PluginClean, it warns that it will remove YouCompleteMe, flashes an error for an instant, then shows error 'C:\Program' is not recognized as an internal or external command, operable program or batch file.

The instantaneous error is

Processing 'YouCompleteMe'
Error detected while processing function vundle#installer#clean[25]..<SNR>20_process[11]..vundle#installer#run[8]..vundle#installer#delete[9]..<SNR>20_system:

My $/_vimrc is this with some commented lines:

The YouCompleteMe errors and incorrect :PluginList output persists after removing everything in $VIM/bundle and re-cloning Vundle.Vim

I failed to mention I'm on windows 10 running git bash in hyper, with recent vim binaries

attn @sryze , xposting workarounds from vim-plug#539:

:PlugInstall works fine if i start gvim from the windows start menu.

I discovered i'm able to get it working by changing &shell in .vimrc to 'cmd.exe'. I'm not sure how that effects other things i may try to do, but it makes PlugInstall work!

"let &shell='/usr/bin/bash'
let &shell='cmd.exe'

The second workaround fixed it for me

[therealplato]

perhaps @janlazo's fix is portable to vundle? https://github.com/junegunn/vim-plug/pull/676

[janlazo]

Vim picks up SHELL and if it is not cmd.exe, Vim will use the default values for shell-related options so the user has to revert all of those options themselves. Windows Vim does not work well with shells other than cmd.exe. For any command requiring the shell, after set shell=cmd.exe, there are at least 2 options:

1. Revert all shell-related options to work with cmd.exe (best done by the user in their vimrc)
2. Put the command in a temporary batchfile (make sure this batchfile has the bat or cmd extension)

junegunn/vim-plug#676 opts for the batchfile because it is already tested in the Vim plugin of fzf and fzf.vim. Note that the escape code for option 1 is different from option 2 because %% is a literal % in a batchfile only. Also, literal escaping is used in vim-plug.

I am experience the same issue. PluginList shows the plugins as installed but they are not as the commands don't show up and when I search for the plugin name system wide (using the Everything search plugin), there are no files related to it.

EDIT: I tried the let &shell='cmd.exe' fix posted above but it didn't work :(

Is there any way to keep using bash while having Vundle work? Can I instruct vundle to use cmd.exe but keep using bash myself?
