无法上班CocoaPods和Yosemite

Question

我已经尝试过这个步骤：

1. 打开Xcode 6打开首选项
2. 单击“位置”选项卡
3. 将命令行工具版本更改为Xcode 6.0
4. 卸载cocoapods
5. 一个。 $ sudo gem uninstall cocoapods安装xcodeproj
6. 一个。 $ sudo gem install
7. xcodeproj安装cocoapods
8. 一个。 $ sudo gem install cocoapods
9. 运行pod --version以验证它是否有效

但是当我进行pod安装或pod --version时，我仍然会这样做：

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：

1. 更新宝石 sudo gem update --system
2. 卸载xcodeproj sudo gem uninstall xcodeproj
3. 确保选择所有版本
4. 卸载了Cocoapods sudo gem uninstall cocoapods
5. 安装xcodeproj sudo gem install xcodeproj
6. 安装cocoapods sudo gem install cocoapods
7. 跑 pod --version to test.

Answer 2

运行这两行将解决您的问题

sudo gem update --system

sudo gem安装cocoapods

Answer 3

我不得不卸载cocoapods的整个依赖链，以使其工作。

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

Answer 4

许多问题是由于系统范围的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接近。

$ 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）

$ which ruby

应该显示/ usr / local / bin / ruby​​（现在应该指向“local”目录，而不是“/ usr / bin”，如果不适合你，请确保修改路径顺序）

现在你应该能够安装xcodeproj和cocoapods而不使用“sudo”：

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

（我正在使用预发布版本，如果你想使用发行版，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

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
