为什么不能在OS X 10.8上安装json 1.7.4 gem？ [英] Why won't bundler install the json 1.7.4 gem on OS X 10.8?

问题描述

当我从git复制我的rails项目并运行时：

我使用XCode 4.4，Ruby 1.9.3和Rails 3.2在OS X 10.8上。 / p>

 捆绑安装
  

我得到：

安装json（1.7.4）
Errno :: EPERM：不允许操作 - /Users/myuser/.rvm/ gems / ruby​​-1.9.3-p0 / gems / json-1.7.4 / .gitignore
安装json（1.7.4）时发生错误，并且Bundler无法继续。
确保 gem install json -v'1.7.4'在捆绑之前成功。

然后，

然后我试试：

  gem install json -v'1.7.4'
  

并获得：
$ b 错误：执行gem时（Errno :: EPERM）
操作不允许 - /Users/scalessec/.rvm/gems/ruby-1.9.3-p0/gems/json-1.7.4/.gitignore

好的。权限问题，对吗？让我们试试：

  sudo gem install json -v'1.7.4'
  

不行。这是我得到的：

构建原生扩展。这可能需要一段时间...
错误：安装json时出错：
错误：无法构建gem原生扩展。

<用户名> / users /.rvm/rubies/ruby-1.9.3-p0/bin/ruby extconf.rb

编译generator.c

我的导轨配置工作正常）。
和我有相同的json 1.7.4问题。

最后，我通过注意到Xcode的命令行工具没有安装（但它们在OS X 10.7！）。 我只是在Xcode中重新安装了CLI工具，并且json 1.7.4问题消失了。 =http://robots.thoughtbot.com/post/27985816073/the-hitchhikers-guide-to-riding-a-mountain-lion =nofollow> http://robots.thoughtbot.com/post/ 27985816073 / the-hitchhikers-guide-to-riding-a-mountain-lion

I'm on OS X 10.8 with XCode 4.4, Ruby 1.9.3, and Rails 3.2.

When I clone my rails project from git and run:

bundle install

I get:

Installing json (1.7.4) Errno::EPERM: Operation not permitted - /Users/myuser/.rvm/gems/ruby-1.9.3-p0/gems/json-1.7.4/.gitignore An error occurred while installing json (1.7.4), and Bundler cannot continue. Make sure that gem install json -v '1.7.4' succeeds before bundling.

Then I try:

gem install json -v '1.7.4'

and get:

ERROR: While executing gem ... (Errno::EPERM) Operation not permitted - /Users/scalessec/.rvm/gems/ruby-1.9.3-p0/gems/json-1.7.4/.gitignore

Okay. Permissions issue, right? Let's try:

sudo gem install json -v '1.7.4'

No go. Here's what I get:

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

/Users/myuser/.rvm/rubies/ruby-1.9.3-p0/bin/ruby extconf.rb creating Makefile

make compiling generator.c make: /usr/bin/gcc-4.2: Permission denied make: * [generator.o] Error 1

What the heck?

解决方案

I am not sure, but i upgraded to OS X 10.8 2 days ago (from Lion where my rails configuration worked fine). And i had the same json 1.7.4 issue.

Eventually i solved the problem by noticing that Xcode's command line tools where NOT installed (but they were on OS X 10.7!). I just reinstalled CLI tools in Xcode and that json 1.7.4 issue dissappeared.
