`/usr/lib/ruby/gems/3.0.0/cache`. It is likely that you need to grant write permissions for that path.

I am trying to execute `$ bundle install` in jekyll-generated folder, in Arch Linux. but I am having the following issue.
```
Bundler::PermissionError: There was an error while trying to write to `/usr/lib/ruby/gems/3.0.0/cache`. It is likely
that you need to grant write permissions for that path.
```
what I am missing.
