RVM installation and use help

 

This plug-in is very convenient to install and switch ruby versions. It is strongly recommended that the ruby version of the Mac system is outdated. Therefore, you need a tool to manage it and install RVM.

Bash and git are required. The installation of these two tools is very simple.

Run the following command to install RVM:

Bash <(curl http://rvm.beginrescueend.com/releases/rvm-install-head)

 

Then modify the user configuration file/Users/username/. profile. You can also write it to other global configurations.

Add a line of code:

[[-S "$ HOME/. rvm/scripts/rvm"] &. "$ HOME/. rvm/scripts/rvm" # This loads RVM into a shell session.

 

Restart Terminal and RVM has been installed. sudo is not required during RVM usage, and gem is not required.

Then you can install ruby, for example:

Rvm install ruby-1.8.7 -- head -- docs

 

--docsIs automatically generated after compilation and installation,--headIs the latest version

Delete a specific version of ruby and delete both the document and gems. Then:

Rvm remove Ruby-1.8.7 -- docs -- gems

 

Select version:

Rvm use Ruby-1.8.7 -- default

 

Query the current version:

Rvm info

 

 

List versions:

Rvm list
