无法安装 rails
Cant install rails
我进行了新设置，但在尝试安装时总是出现错误 rails。我已经使用 RVM 使用 ruby 2.2.2，并且检查了配置文件。
我已经学习了各种教程。我已经卸载了 gcc（尽管我可能会重新安装 xcode）
并且我已经阅读了各种关于如何安装它的教程

IMPORTANT NOTICE:
Building Nokogiri with a packaged version of libxml2-2.9.2
with the following patches applied:
- 0001-Revert-Missing-initialization-for-the-catalog-module.patch
- 0002-Fix-missing-entities-after-CVE-2014-3660-fix.patch
Team Nokogiri will keep on doing their best to provide security
updates in a timely manner, but if this is a concern for you and want
to use the system library instead; abort this installation process and
reinstall nokogiri as follows:
gem install nokogiri -- --use-system-libraries
[--with-xml2-config=/path/to/xml2-config]
[--with-xslt-config=/path/to/xslt-config]
If you are using Bundler, tell it to use the option:
bundle config build.nokogiri --use-system-libraries
bundle install
Note, however, that nokogiri is not fully compatible with arbitrary
versions of libxml2 provided by OS/package vendors.

手动安装 nokogiri
gem install nokogiri -v VERSION_YOU_WANT -- --use-system-libraries
查看“nokogiri gem installation error”。
我会推荐运行
brew doctor
rvm reinstall
rvm reinstall (ruby version here)
gem pristine all
sudo gem install rails
在你之前 运行 bundle install, 运行:
bundle config build.nokogiri --use-system-libraries
或
gem install nokogiri -- --use-system-libraries
之后你可以运行:
bundle install
对于其他错误，请阅读 Nokogiri install documentation。
我浏览了各种教程，我的输出如下所示：

An error occurred while installing byebug (5.0.0), and Bundler cannot continue.
Make sure that `gem install byebug -v '5.0.0'` succeeds before bundling.
重要的部分是
make: /usr/bin/gcc-4.2: No such file or directory
之后我问：
$which gcc
/usr/bin/gcc
关注“OS X Mountain Lion: gcc-4.2 No such file or directory”，之后一切都应该正常。
如果遇到很多错误，最好的办法是完全删除 rails 和 ruby
首先输入这个
tarun@tarun:~$ which ruby
/home/tarun/.rbenv/shims/ruby
tarun@tarun:~$ which rails
/home/tarun/.rbenv/shims/rails
然后复制路径并使用此命令删除文件
rm -rf /home/tarun/.rbenv/shims/ruby
rm -rf /home/tarun/.rbenv/shims/rails
同样，您可以使用相同的方法检查哪个 rbenv 和哪个 rvm 并删除。
并使用
grep -rl rails
grep -rl ruby
这将显示所有具有 rails keyword.So 的文件的路径，您可以知道您是否已完全删除 rails 和 ruby。
并按照此处给出的步骤重新安装它
