第一次安装 Cocoapods 时遇到问题

Question

我正在尝试使用以下方法安装 cocoapods：

sudo install cocoapods

这是我收到的回复

usage: install [-bCcpSsv] [-B suffix] [-f flags] [-g group] [-m mode]
               [-o owner] file1 file2
       install [-bCcpSsv] [-B suffix] [-f flags] [-g group] [-m mode]
               [-o owner] file1 ... fileN directory
       install -d [-v] [-g group] [-m mode] [-o owner] directory ...

这是我第二次尝试安装 cocoapods。第一次尝试安装失败，说我可能需要安装 ruby-dev？我尝试安装它，然后开始收到上述消息。

Answer 1

安装Cocoapods的正确命令是：

sudo gem install cocoapods

如他们的 Getting Started 页面所示。

Answer 2

谢谢！在使用 "gem" 我运行进入以下问题后：

    Building native extensions. This could take a while...
ERROR:  Error installing cocoapods:
    ERROR: Failed to build gem native extension.

    current directory: /Library/Ruby/Gems/2.6.0/gems/ffi-1.12.2/ext/ffi_c
/System/Library/Frameworks/Ruby.framework/Versions/2.6/usr/bin/ruby -I /System/Library/Frameworks/Ruby.framework/Versions/2.6/usr/lib/ruby/2.6.0 -r ./siteconf20200415-22388-129pjat.rb extconf.rb
mkmf.rb can't find header files for ruby at /System/Library/Frameworks/Ruby.framework/Versions/2.6/usr/lib/ruby/include/ruby.h

You might have to install separate package for the ruby development
environment, ruby-dev or ruby-devel for example.

extconf failed, exit code 1

Gem files will remain installed in /Library/Ruby/Gems/2.6.0/gems/ffi-1.12.2 for inspection.
Results logged to /Library/Ruby/Gems/2.6.0/extensions/universal-darwin-19/2.6.0/ffi-1.12.2/gem_make.out

我发现我需要使用 xcode 安装一些额外的项目：

xcode-select --install

安装并重新启动计算机大约 20 分钟后，我就可以使用了：

sudo gem install cocoapods
