There was an error while trying to write to C:/Users/REMOTE~1/AppData/ on Bundle Install [Rails 5.1.3, Ruby 2.3.3]

Been scratching my heads for hours over this.

All of a sudden I am unable to run the commands bundle update and bundle install on my projects.

I receive the following errors:

There was an error while trying to write to C:/Users/REMOTE~1/AppData/Local/Temp/bundler-compact-index-20181216-9268-sd4t9f/versions. It is likely that you need to grant write permissions for that path.

1.) That path and user do not exist

2.) I have looked at env variables and they all point to my user

3.) This has nothing to do with my project as even if I try to create a new rails project, part of the rails new command runs 'bundle install' and so that fails too.

4.) I am an administrator so I don't understand why I wouldn't have full read/write access.

Solution

After 3 days of tinkering and trying to find a solution I came up with the following.

1.) As @anothermh mentioned, it is probably best to install Ruby on Windows Subsystem for Linux Installing Ruby on WSL (Windows Subsystem for Linux) to avoid these kind of situations.

2.) For people who still want to continue using Ruby on their windows systems.

This error occurs when your bundler rubygems copy is corrupted and gets cached into your system.

I solved this by deleted the folder .bundle in C:/users/my_user/.bundle

Re-install bundler and this error goes away and your gems compile and install as usual.
