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:

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

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

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
错误:错误安装cocoapods:错误:未能建立gem本地扩展
首先安装Ruby版本管理器rvm:
curl -L https://get.rvm.io | bash -s stable
然后使用
source ~/.rvm/scripts/rvm
然后安装最新版本的ruby:
rvm install ruby-2.7.2
然后流这个(你的终端)输出。
echo 'eval "$(/opt/homebrew/bin/brew shellenv)"' >> /Users/nec/.zprofile
然后使用
eval "$(/opt/homebrew/bin/brew shellenv)"
最后再次尝试安装cocoapods:
sudo gem install cocoapods
我的解决方法:
首先，我有新的mac os 10.15.7和Xcode
以前的解决方案对我也没用
我注意到pods安装在库2.6.0，并决定它需要更新:
步骤1
\curl -sSL https://get.rvm.io | bash -s stable --ruby
Ok!
然后我检查了版本:2.6.0 -为什么?
在安装ruby后的最后一个字符串中，我注意到:
要开始使用RVM，您需要运行source /Users/abazhanov/.rvm/scripts/ RVM
在所有打开的shell窗口中，在极少数情况下需要重新打开所有shell窗口。
好吧，我们开始吧:
步骤2
source /Users/abazhanov/.rvm/scripts/rvm
然后我检查了版本:2.7.0 -它是好的!
步骤3
sudo gem install cocoapods
结果是:安装了34个宝石
我知道新版本的Pods根本没有安装在旧版本的Ruby上
