Question

我正在尝试在全新的 Mac OS X 11.1 上安装 cocoapods。我已经运行了这些命令：

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

但是，当我运行最后一个命令时，出现此错误：

ERROR:  Error installing cocoapods:
    ERROR: Failed to build gem native extension.

    current directory: /Library/Ruby/Gems/2.6.0/gems/ffi-1.14.2/ext/ffi_c
/System/Library/Frameworks/Ruby.framework/Versions/2.6/usr/bin/ruby -I /Library/Ruby/Site/2.6.0 -r ./siteconf20201226-10485-158gl5m.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-1.14.2 for inspection.
Results logged to /Library/Ruby/Gems/2.6.0/extensions/universal-darwin-20/2.6.0/ffi-1.14.2/gem_make.out

我该怎么做？

Answer 1

sudo gem update --system

xcode-select --install

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

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

解决了我的问题

Answer 2

这里提出的解决方案都不适合我，我的解决方案是将 ruby 更新到这个版本：

rvm install ruby-2.6.3
rvm use ruby-2.6.3
rvm --default use 2.6.3

然后运行：

sudo gem install cocoapods

如何修复“错误：无法构建 gem 本机扩展。”安装 cocoapods 时出错？
