爲什麼RVM試圖用'rvm install'命令來安裝Rubygems而不是Ruby？

Question

我試圖在我的Debian服務器上安裝Ruby 2.0，並決定通過RVM來做到這一點。我下載它使用：

~$ \curl -L https://get.rvm.io | bash -s stable 

但是，當我嘗試安裝Ruby，它看起來像RVM試圖安裝Rubygems代替。

~$ rvm install 2.0.0 
=> 'ruby' was not found, cannot install rubygems unless ruby is present (Do you have an RVM ruby installed & selected?) 

我檢查了RVM文件和rvm install <ruby version>絕對是安裝Ruby，RubyGems的不是命令。那麼爲什麼會出現上述問題？謝謝！

我不知道我理解你如何到達這一情況，但如果你想通過RVM安裝ruby 2.0，那麼我會建議如下：

rvm implode 
\curl -L https://get.rvm.io | bash -s stable --ruby 

然後確保您的源〜/ .bash_profile（如安裝輸出中所述）在每個新shell中加載RVM。
