ruby - 通过 Ruby 安装 Cocoapods 会导致错误

问题描述

我尝试像这样安装 Cocoapods

sudo gem install cocoapods

这是我得到的输出：

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

To see why this extension failed to compile, please check the mkmf.log which can be found here:

extconf failed, exit code 1

Gem files will remain installed in /Library/Ruby/Gems/2.6.0/gems/ffi-1.14.2 for inspection.

基本上就是这个

/System/Library/Frameworks/Ruby.framework/Versions/2.6/usr/lib/ruby/2.6.0/mkmf.rb:467:in `try_do'：编译器无法生成可执行文件。(RuntimeError) 你必须先安装开发工具。

我必须先安装哪些开发工具？xCode 以及 Xcode 命令行工具已安装。我在 OS X 10.15.7 上，Xcode 是最新的。

解决方案

几个小时后终于收到了。我按照这个说明做了一些改动

  1. 确保brew已安装。如果不 /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"

  2. 将外壳设置为zsh curl -L http://install.ohmyz.sh | sh

或者，设置 PATH

  1. eval "$(rbenv init -)"

  2. 安装 Ruby 版本管理器 brew update brew install rbenv ruby-build

  3. 安装 Ruby rbenv install 2.6# 我使用我的系统默认版本号，因为我不确定它是否与我的 OS X 系统版本混淆。 rbenv global 2.6 rbenv rehash

  4. 将其添加到您的 zsh echo 'eval "$(rbenv init -)"' >> ~/.zshrc source ~/.zshrc

那是为我做的。所有其他的东西，比如安装 Xcode，接受 Xcode 许可证，Xcode 命令行工具都没有这样做。
