我在安装 cocoapods 时遇到了一些问题

Question

我正在尝试将 cocoapods 安装到我的 MacBook，在我将此代码运行到终端后，gem install cocoapods我收到以下错误：

****** ~ % sudo gem install cocoapods

    Password:
    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 ./siteconf20200413-663-1dklrnl.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.

Answer 1

看起来您还没有安装 Ruby 开发头文件。

您可以通过执行以下两个命令来安装 Xcode 命令行工具来解决此问题：

xcode-select --install
sudo xcodebuild -license

更改将在计算机重新启动后应用。

Answer 2

转到 Xcode 首选项，然后单击 Locations -> Command Line Tools -> 单击下拉列表并检查是否有任何可用。如果是，则选择并设置它。然后尝试安装可可豆荚，它按预期工作。

如果命令行工具的下拉菜单中没有可用选项，则使用以下命令

xcode-select --install
sudo xcodebuild -license
