Question

我最近从Linux切换到了Mac，在尝试在之前的某个项目中运行bundle时，我收到以下错误：

我尝试重新安装bundler，rbenv和ruby，但我仍然遇到同样的错误。我使用sudo运行命令并且它有效，如何设置权限而无需使用sudo

Answer 1

我现在用sudo重试了它的确有效。如何在没有sudo的情况下使其工作

要使bundler在没有sudo的情况下工作，您应该将所有gem依赖项安装在本地用户目录中（这是推荐的方式）

bundle install --path vendor/bundle

现在，当您运行程序时，bundle会在新位置找到您的所有库

bundle exec ruby app.rb

如果您使用的是git，请务必将vendor添加到.gitignore，以避免将所有宝石库放入“新文件”列表中。

尝试运行bundle install时，我得到权限被拒绝错误
