Your user account isn’t allowed to install to the system rubygems solution

In today’s development process, I pulled down the code from the master and restarted the project. When I wanted to use the console, I found that I needed a password??And three times after password confirmation or crazy error.

At that time, I first thought that the RVM version was inconsistent, and then I checked the version and gem generation. When I confirmed that the RVM version was correct, and the mandatory use of sudo installation required gem install * * to install the gem package one by one, I was crazy.

The warning is as follows:

Your user account isn't allowed to install to the system RubyGems.
You can cancel this installation and run:

bundle install --path vendor/bundle

to install the gems into ./vendor/bundle/, or you can enter your password
and install the bundled gems to RubyGems using sudo.

Or as follows:

RVM is not a function, selecting rubies with 'rvm use ...' will not work.

You need to change your terminal emulator preferences to allow login shell.
Sometimes it is required to use `/bin/bash --login` as the command.
Please visit for an example.

Guess why:

Rbenv wants to install gem into your system’s own ruby, but your user account does not allow the system to install rubygems, so you need to enter a password to give permission

Solution (input from the console in turn)

1 echo '[[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm"' &>&>~/.bashrc
3 source ~/.bashrc
5 ruby -v

Then it’s solved. We can continue to develop hi PI!!
