Rvm 进行gem安装时必须输入密码Your user account isn't allowed to install to the system RubyGems 解决方案

Posted 2021-01-31 lwh-note

今天开发过程中，从master拉下代码后重启项目，想用控制台时，却发现需要密码？？并且三次密码确认后还是疯狂报错。

当时第一想到是rvm版本不一致，随即则检查了版本跟gem生成，当确认rvm版本无误时，且强制使用sudo安装却需要一条条执行gem install ***安装gem包时，就令我抓狂了。

 

警告提示如下:

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.

或者如下：

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 https://rvm.io/integration/gnome-terminal/ for an example.

 

猜测原因：

     rbenv 要往你系统的自带Ruby里面安装gem，但是你的用户帐户不允许系统安装RubyGems，所以要你输入密码赋予权限

 

解决方案（控制台依次输入）：

1 echo ‘[[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm"‘ >>~/.bashrc
2 
3 source ~/.bashrc
4 
5 ruby -v

然后就解决了，可以继续嗨皮开发了！！
