在OS X上安装Cocoapods El Capitan错误

Question

首先.由于iOS 9.3,我更新了El Capitan,它只支持xCode 7.3.

更新后,我发现该pod命令无法正常工作.我执行了:

sudo gem install cocoapods
ERROR:  Error installing cocoapods:
    activesupport requires Ruby version >= 2.2.2.

所以我的问题是我无法安装cocoapods.我对宝石和红宝石的东西一无所知.有人知道如何处理这个问题吗？

我有El Capitan 10.11.4的第二个OS X,一切都很好,所以我不知道这个问题来自哪里.

我在终端上执行了几个命令以获取更多信息:

当我试图用rvm安装Ruby时

Kapucha:local kapucha$ rvm install 2.2.2
Searching for binary rubies, this might take some time.
Found remote file https://rvm_io.global.ssl.fastly.net/binaries/osx/10.11/x86_64/ruby-2.2.2.tar.bz2

...
ERROR: '/bin' is not writable - it is required for Homebrew, try 'brew doctor' to fix it!

尝试酿造医生的结果相同:

Kapucha:local kapucha$ brew doctor

Answer 1

这是一个比其他'安装自制软件/使用rvm'建议更简单的解决方案 - 首先安装旧版本的'activesupport'(它与ruby 2.0和cocoapods兼容),然后安装cocoapods.

sudo gem install activesupport -v 4.2.6
sudo gem install cocoapods

这是cocoapods错误报告,提出了这种解决方法.

Answer 2

1. 使用此命令安装Homebrew

   ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
   

2. 现在我们已经安装了Homebrew,我们可以用它来安装Ruby.我们将使用rbenv来安装和管理我们的Ruby版本.为此,请在终端中运行以下命令:

   brew install rbenv ruby-build
   

3. 现在安装ruby

   echo 'if which rbenv > /dev/null;
   
   then eval "$(rbenv init -)";
   
   fi' >> ~/.bash_profilesource ~/.bash_profile
   
   rbenv install 2.3.1
   
   rbenv global 2.3.1 
   
   ruby -v
   

4. 安装cocoapods

   sudo gem install cocoapods
   

Answer 3

最后我解决了这个问题。

目标是安装 cocoapods，但出现错误，我需要 ruby​​ >= 2.2.2。

由于错误，安装rvm install 2.2未完成：

/System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0/fileutils.rb:245:in `mkdir': Permission denied - /Library/Ruby/Gems/2.0.0/extensions/universal-darwin-15 (Errno::EACCES)

运行brew 会导致相同的错误。所以我决定先修复brew。通过卸载并重新安装已修复。这并不容易。卸载脚本不起作用，因为我.git在/usr/local.

我决定提供 .git 文件夹。

我克隆git clone https://github.com/Homebrew/homebrew.git到一些临时文件夹，然后cp -r .git /usr/local/最后.git我的brew文件夹中有文件夹/usr/local。此后我能够在 El Capitan 上卸载并安装新鲜的酿造。请查看此链接的第 2 部分。

/usr/local根据此，通过工作brew和El Capitan的固定权限，我可以使用rvm安装ruby：

rvm install 2.2
rvm use 2.2

最后为 El Capitan 安装 cocapods：

sudo gem install -n /usr/local/bin cocoapods
