在rails安装Ubuntu 12.04期间出错

Question

我在Ubuntu机器上安装rails,到目前为止我在阅读以下教程时没有遇到任何问题:

但是当我尝试安装rails时:

宝石安装导轨

我收到以下错误:

Building native extensions.  This could take a while...
ERROR:  Error installing rails:

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

显然我已经检查过make是否可用,并且它已经在PATH上了.事实上,哪个和哪个rvm给出了以下结果:/ usr/bin/make/usr/local/rvm/bin/rvm

所以......我不认为这与PATH有关.

有任何想法吗？？我该怎么办？

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

我遇到了同样的问题...在'sudo apt-get install build-essentials'之后运行'rvm reinstall 1.9.3'为我修复了它.我想也许红宝石没有注意到我安装gcc时,仍然相信我没有它.
