Nvim-tree.lua: attempt to call field 'win_open' (a nil value)

[GustavoPrietoP]

I don't know if this has to do with a recent update or not but I recently updated my nvim-tree and its giving me this error

[agibson-bluecat]

Looks like this function was moved to view.lua, and updated slightly (used to be in lib.lua). Changing the call at nvim-tree.lua line 165 from lib.win_open() to view.win_open() does the trick.

[agibson-bluecat]

Just a slight oversight from the most recent commit (ff814676), which was made today

I am experiencing the same issue after the update.

It seems like nvim-tree is using a new Neovim api.
Updating Neovim nightly build seems to fix the issue.

sorry, forgot to change this func call. It's fixed in d065927
