在rails安裝Ubuntu 12.04期間出錯

Question

我在Ubuntu機器上安裝rails，到目前為止我在閱讀以下教程時沒有遇到任何問題：

但是當我嘗試安裝rails時：

寶石安裝導軌

我收到以下錯誤：

Building native extensions.  This could take a while...
ERROR:  Error installing rails:
ERROR: Failed to build gem native extension.

Gem files will remain installed in /usr/local/rvm/gems/ruby-1.9.3-p374/gems/json-1.7.6 for inspection.
 Results logged to /usr/local/rvm/gems/ruby-1.9.3-p374/gems/json-1.7.6/ext/json/ext/generator/gem_make.out

顯然我已經檢查過make是否可用，並且它已經在PATH上了。 事實上， 哪個和哪個rvm給出了以下結果：/ usr / bin / make / usr / local / rvm / bin / rvm

所以......我不認為這與PATH有關。

有任何想法嗎？？ 我該怎么辦？

Answer 1

你缺少必需的包裹：

rvm get head
rvm requirements run
rvm remove 1.9.3
rvm use 1.9.3 --install --default
gem install rails

Answer 2

我遇到了同樣的問題...在'sudo apt-get install build-essentials'之后運行'rvm reinstall 1.9.3'為我修復了它。 我想也許紅寶石沒有注意到我安裝gcc時，仍然相信我沒有它。
