我试图将cocoapods安装到运行OSX 10.9.1(新Mavericks)的MacBook Pro上,键入gem install cocoapods后,我得到以下错误:

当前回答

以前的解决方案对我都没用。

我的情况是一个新的干净安装的macOS Catalina + XCODE;

碰巧在安装可可豆之前,我必须首先运行Xcode(在第一次运行中,Xcode设置机器与工具);

在那之后,可可豆荚就正常了。

其他回答

我的配置中有多个环境,这导致了问题,因为rvm会干扰安装。曾经的红宝石2。检测到X,安装正常。

对于我的环境,我做了以下工作: 1. xcode-select——安装 2. rvm implode(注意-太激烈了-你可能不需要这样做,我对旧的ruby安装没有任何用途,我通过rvm uninstall逐个删除它们,然后使用rvm implode 3.Gem安装cocoapods

这一次,最后一个命令运行正常,没有任何问题。

如果您通过Brew安装它,您可以使用一个简单的命令来解决它。

brew update

brew upgrade

首先,检查您正在使用的Ruby版本。

$ruby -v
ruby 2.7.1p83 (2020-03-31 revision a0c7c23c9c) [x86_64-darwin18]
$ which ruby
usr/bin/ruby

现在使用Homebrew安装最新的Ruby。

$ brew install ruby
==> ruby
By default, binaries installed by gem will be placed into:
/usr/local/lib/ruby/gems/2.7.0/bin

You may want to add this to your PATH.

ruby is keg-only, which means it was not symlinked into /usr/local,
because macOS already provides this software and installing another version in
parallel can cause all kinds of trouble.

如果你需要在PATH运行中先使用ruby:

$ echo 'export PATH="/usr/local/opt/ruby/bin:$PATH"' >> /Users/xxx/.bash_profile

为了让编译器找到ruby,你可能需要设置:

$ export LDFLAGS="-L/usr/local/opt/ruby/lib"
$ export CPPFLAGS="-I/usr/local/opt/ruby/include"

按照说明设置PATH。现在您将看到已安装的Ruby。确保将“xxx”替换为您的用户名。

$ echo 'export PATH="/usr/local/opt/ruby/bin:$PATH"' >> /Users/xxx/.bash_profile
$ echo 'export LDFLAGS="-L/usr/local/opt/ruby/lib"' >> ~/.bash_profile
$ echo 'export CPPFLAGS="-I/usr/local/opt/ruby/include"' >> ~/.bash_profile

$ source ~/.bash_profile

最后,确保PATH已经就位。

$ ruby -v
ruby 2.7.1p83 (2020-03-31 revision a0c7c23c9c) [x86_64-darwin18]
$ which ruby
/usr/local/opt/ruby/bin/ruby

你可以开始了!确保按照如下方式指定保存目的地进行安装。

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

执行以下命令

 brew cleanup -d -v 

然后运行以下命令

brew install cocoapods 

注意:如果你看到链接失败,那么运行brew link cocoapods

如果链接失败,则运行

酿造链接——覆盖cocoapods

这就是我解决问题的方法

对于拥有m1芯片系统的人来说,他们需要通过罗塞塔运行这个

选择“终端”并按cmd(⌘)+I,并检查“使用Rosetta打开”选项。(适用于基于m1芯片的mac)

brew reinstall ruby

将以下内容添加到您的路径中

export PATH="/usr/local/opt/ruby/bin:$PATH"

如果需要,添加这些标志。

export LDFLAGS="-L/usr/local/opt/ruby/lib"
export CPPFLAGS="-I/usr/local/opt/ruby/include"
