Question

我已经尝试过这个步骤：

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
一个。 $ sudo gem uninstall cocoapods安装xcodeproj
一个。 $ sudo gem install
xcodeproj安装cocoapods
一个。 $ sudo gem install cocoapods
运行pod --version以验证其是否有效

但是当我进行pod安装或pod --version时，我仍然会这样做：

/System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0/rubygems/core_ext/kernel_require.rb:55:in `require': cannot load such file -- xcodeproj/prebuilt/universal.x86_64-darwin14-2.0.0/xcodeproj_ext (LoadError)

Answer 1

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 update --system
已卸载xcodeproj

sudo gem uninstall xcodeproj
确保选择所有版本
卸载Cocoapods

sudo gem uninstall cocoapods
安装xcodeproj

sudo gem install xcodeproj
安装cocoapods

sudo gem install cocoapods
运行

pod --version to test.

Answer 2

运行这两行将解决您的问题

sudo gem update --system

sudo gem install cocoapods

Answer 3

我必须卸载cocoapods的整个依赖关系链才能使它工作。

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

Answer 4

许多问题都是因为系统范围内的ruby安装，它迫使开发人员一直使用“sudo”（好吧，我们做了多少次“ sudo gem install cocoapods --pre “）。我最近有同样的问题试图安装预发布版本的cocoapods（权限搞砸了）。所以这是一个适合我的方法。

$ 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

（关闭并打开终端窗口有时会有帮助）

$ which ruby

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

现在你应该可以在不使用“sudo”的情况下安装xcodeproj和cocoapods：

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

（我正在使用预发布版本，如果你想使用版本，只需删除--pre。）

错误'require': cannot load such file表示您有一些丢失或损坏的gem包。您可以通过重新安装cocoapods来修复它：

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

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安装它：

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

Answer 6

您必须先执行此命令：

sudo gem install cocoapods

这将更新所有过时的宝石

无法上班CocoaPods和Yosemite
