How to get QPixel bundle install working without sudo privileges on Debian? Question

−0

When I tried to install QPixel with bundle install I got the following message (on Debian 11):

~/qpixel$ bundle install
Bundler 2.3.15 is running, but your lockfile was generated with 2.4.13. Installing Bundler 2.4.13 and restarting using that version.
Fetching gem metadata from https://rubygems.org/.
Fetching bundler 2.4.13
Installing bundler 2.4.13

Then I am asked for the sudo password and afterwards a lot of orange warnings appear like this one (several for each "fetched" gem):

Retrying download gem from https://rubygems.org/ due to error (2/4): Bundler::PermissionError There was an error while trying to write to `/var/lib/gems/3.1.0/cache/erubi-1.11.0.gem`. It is likely that you need to grant write permissions for that path.

And then the installation stops with the following red error message (similar error messages are displayed):

Bundler::PermissionError: There was an error while trying to write to
`/var/lib/gems/3.1.0/cache/concurrent-ruby-1.1.10.gem`. It is likely that
you need to grant write permissions for that path.

An error occurred while installing minitest (5.16.3), and Bundler cannot continue.

[..] # Similar error messages apears after

So I have to run bundle with sudo: sudo bundle install and I got the following message (but the installation is successful):

~/qpixel$ sudo bundle install
Don't run Bundler as root. Bundler can ask for sudo if it is needed, and installing your bundle as root will break this application for all non-root users on this machine.
Bundler 2.3.15 is running, but your lockfile was generated with 2.4.13. Installing Bundler 2.4.13 and restarting using that version.

[..] # After, the installation proceeds correctly

It seems to work fine because I have not detected any problem when running the local instance of QPixel, even if I start it with rails s without sudo.

But my questions are:

What are the possible issues related to a QPixel bundle install with sudo?
How to avoid using sudo to obtain a successful QPixel bundle install?
I tried to install first the "good" version of bundle with sudo gem install bundler:2.4.13 but I got the same PermissionError messages during the bundle install... EDIT 1.1 after answer: If I try to install bundle WITHOUT sudo, I got the following error message:
```
~/qpixel$ gem install bundler
Fetching bundler-2.4.16.gem
ERROR:  While executing gem ... (Gem::FilePermissionError)
    You don't have write permissions for the /var/lib/gems/3.1.0 directory.
```

Set up

WSL2 Debian 11

I tried on a fresh Debian 11 bullseye on Windows Subsystem Linux Version 2 (WSL2), Windows 11 22H2 host and bundle installed with:

sudo apt install bundler

Ruby installed with:

curl -sSL https://get.rvm.io | bash -s stable

EDIT 1.2 after answer:

Output of gem env ("tyty" is the Debian user and "Rigal" is the Windows host user)

Debian 12 on VBox

Also tried with a fresh install of Debian 12 (iso image debian-12.0.0-amd64-netinst.iso) on Virtual Box (version 7.0.8) on Windows 11 22H2 Host.

Ruby installed with rbenv:

sudo apt install rbenv
rbenv install 3.1.2 # WITHOUT sudo!
sudo gem install bundler

The same errors occurs when trying the QPixel bundle install without sudo and if I tried to install bundle without sudo (i.e. with gem install bundler), see EDIT 1.1.

Output of gem env ("tyty" is the Debian user, and note that I tried to install first Ruby with rvm (but it fails) before to install it with rbenv...)
