Rails - 用json捆绑安装问题

Question

我正在使用Rails 3.2.12运行OS X Mavericks.当我尝试使用rails new project时,它会在bundle install中遇到困难.

Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.

/usr/local/rvm/rubies/ruby-1.9.3-p392/bin/ruby extconf.rb 
creating Makefile

make
compiling generator.c
make: gcc-4.2: No such file or directory
make: *** [generator.o] Error 1


Gem files will remain installed in /usr/local/rvm/gems/ruby-1.9.3-p392/gems/json-1.8.1 for inspection.
Results logged to /usr/local/rvm/gems/ruby-1.9.3-p392/gems/json-1.8.1/ext/json/ext/generator/gem_make.out
An error occurred while installing json (1.8.1), and Bundler cannot continue.
Make sure that `gem install json -v '1.8.1'` succeeds before bundling.

当我做'gem install json ....'时,我得到同样的错误.我已经使用命令行工具安装了最新版本的Xcode.当我做:

which gcc

我明白了:

/usr/bin/gcc

我真的很喜欢这些东西,所以请尽量保持简单.

Answer 1

因此,在XCode 5之前,有一个gcc-4.2二进制文件,它在升级中被删除了.

我发现本教程有助于恢复gcc-4.2并使用ruby运行.它假设您使用自制软件来管理Mac上的软件包.
