我試圖在我的amazon實例上安裝ruby gems時出現此錯誤。誰能解釋一下?rubygems錯誤安裝rails
[email protected]:~$ sudo apt-get install rubygems
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package rubygems is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
However the following packages replace it:
ruby
E: Package 'rubygems' has no installation candidate
我不明白那條消息。我從http://www.frontcoded.com/rails-on-amazon-ec2-ubuntu.html以下說,要做到這一點的方向。我也試過
which rubygems
然後就出來了。如果可能的話,我想回答這個問題來阻止反對票。謝謝。
您是否閱讀過apt-get的消息? –
