Ruby Can'；CocoaPods和Yosemite不能上班

我已经尝试了以下步骤：

打开Xcode 6打开首选项

单击“位置”选项卡

将命令行工具版本更改为Xcode 6.0

卸载cocoapods

a$sudo gem卸载cocoapods安装xcodeproj

a、 美元sudogem安装

xcodeproj安装cocoapod

a、 美元sudogem安装cocoapod

运行pod--version以验证它是否工作

但当我安装pod或pod--版本时，我仍然会得到这些信息：

如果其他人遇到同样的问题，我这样做是为了解决我的问题：

更新宝石

sudo gem更新——系统

卸载的xcodeproj

sudo gem卸载xcodeproj

确保选择所有版本

卸载的Cocoapods

sudo gem卸载cocoapods

安装xcodeproj

sudo gem安装xcodeproj

安装cocoapod

sudo gem安装cocoapods

跑

pod——要测试的版本。

---

错误

'require'：无法加载此类文件

表明您丢失或损坏了一些gem包。您可能可以通过重新安装CoCoapod来修复此问题：

gem uninstall cocoapods # Follow by sudo if necessary
gem install cocoapods --verbose # Follow by sudo if necessary

并确保您的xcodeproj存在：

gem install xcodeproj --verbose # Follow by sudo if necessary

---

如果没有帮助，请尝试使用较旧的Ruby进行安装：

sudo ln -s /Library/Ruby/Gems/1.8/gems/rubygems-update-1.8.12/bin/gem /usr/bin/gem18
sudo gem18 install cocoapods

见：

---

我必须卸载CoCoapod的整个依赖链才能让它正常工作

for i in `gem list --no-versions`; do gem uninstall -aIx $i; done

---

请参见

在执行以下命令之前，您只需执行此命令：

sudo gem install cocoapods

---

这将更新所有过时的gems

运行这两行将解决您的问题

sudogem更新——系统

sudogem安装cocoapod

---

很多问题都是因为系统范围的ruby安装，它迫使开发人员一直使用“sudo”（好吧，我们使用了多少次“sudogem install cocoapods--pre”）。我最近在安装cocoapods的预发布版本时遇到了同样的问题（权限被搞乱了）。这是一个对我有效的方法

$ sudo gem uninstall xcodeproj 
$ sudo gem uninstall cocoapods

# Let's restore Apple's ruby installation, the following is for Yosemite that has 2.0 ruby by default 
$ cd /System/Library/Frameworks/Ruby.framework/Versions
$ sudo rm Current
$ sudo ln -s 2.0 Current 
$ brew install ruby

（关闭和打开终端窗口有时会有帮助）

应显示/usr/local/bin/ruby （现在应该指向“本地”目录，而不是“/usr/bin”，如果您不是这样，请确保修改路径顺序）

现在，您应该能够在不使用“sudo”的情况下安装xcodeproj和cocoapod了：

（我使用的是预发布版本，如果您想改用发布版本，只需删除--pre）

享受：）

如果这是您解决问题的方式，请务必将其作为您问题的答案进行检查。直到2天过去，我才可以选择答案。这不再有效。我需要使用0.33.1进行向后兼容。很棒的教程！非常感谢。小改动，应该是

sudo gem uninstall

谢谢AnthonyM，我打字太快了。

$ which ruby

$ gem install xcodeproj --pre
$ gem install cocoapods --pre
