Error when I try to install plugins on Windows

[jdhao]

I am using vim-plug to manage my plugins both on Windows and Linux. But on Windows, I encounter errors sometimes when I try to install new plugins using PlugInstall command. The error is shown blow:

|| Error detected while processing function
C:\Users\Administrator\AppData\Local\nvim\autoload\plug.vim|604| <SNR>2_install[1]

|| E171: Missing :endif

This error seems random and only appear after I have used nvim-qt for some time. If I quit nvim-qt and restart, I can use PlugInstall without any error.

Neovim doesn't support DOS short filenames (see https://en.wikipedia.org/wiki/8.3_filename). fzf.vim uses a workaround for this junegunn/fzf.vim@7e92b73#diff-7274b7c6c87526542ef9087f2e997dfaR40. It can be ported to vim-plug for tempname() but Neovim should handle this internally.

[janlazo]

neovim/neovim#11250 (comment) suggests that it's likely not a DOS shortpath issue but it's up to Neovim to improve tempname. In the meantime, the error should be caught and hidden from the user with a try/catch.

I wanted to share my experience. This problem cropped up about a month ago or so? Same thing here, except I am in Vim/GVim and using Powershell.

In my experience, this is not random, and happens whenever any Plug* command is used. It does seem to install the plugins called for, I've gone through and downloaded the plug script a couple of times and cleared the plugged directory. No such luck.

This is also happening to me on GVim, whenever any Plug command is used. I'm using GVim 8.2 on Windows 10. The exact error message is:

The same thing happened to me using Gvim on Windows 10.
