使用 rails 的捆绑器问题（mac 用户）

Question

当我尝试运行我的应用程序时，出现以下错误：

Could not find racc-1.5.2 in any of the sources
Run `bundle install` to install missing gems.

我跑：

$ bundle install

回复：

Your user account isn't allowed to install to the system RubyGems.
  You can cancel this installation and run:

      bundle config set --local path 'vendor/bundle'
      bundle install

$两次输入密码（系统询问两次）

回复：

ruby 2.6.3p62 (2019-04-16 revision 67580) [universal.x86_64-darwin20]

Bundler 版本 2.2.12（2021-03-01 提交 1de3f8de73）（这是我开始遇到问题的时候）

rails -v
Rails 6.1.3

Answer 1

确保您已授予开发人员工具访问终端的权限，没有它，无论您执行多少次xcode-select --install 都将无法正常工作

Answer 2

我自己也遇到过这个问题。您只需更新适用于 Mac 的 CommandLineTools。

在我的根目录中运行此代码已修复它：

xcode-select --install

Answer 3

您很可能缺少ruby-dev 源库。您也很可能使用系统提供的 ruby​​，而不是安装在您自己的主目录中的 ruby​​。

我强烈建议您安装 rvm 或 rbenv 并使用其中任何一个来配置您的系统。

这里有一些非常完整的 MacOS 安装说明，用于安装和配置 ruby​​ 2.7.1 开发环境。
