尝试运行捆绑安装时出现权限被拒绝错误

Question

我最近从 Linux 切换到 Mac，在尝试在我之前的一个项目上运行 bundle 时，我收到以下错误：

System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0/rubygems/specification.rb:959:in `read': Permission denied - /Library/Ruby/Gems/2.0.0/specifications/puma-2.14.0.gemspec (Errno::EACCES)

我尝试重新安装bundler、rbenv 和ruby，但我一直收到同样的错误。我用sudo 运行命令，它可以工作，我怎样才能设置权限而不必使用sudo

Answer 1

我现在用 sudo 重试，它可以工作。没有 sudo 你怎么能让它工作

要让捆绑器在没有 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 git，请确保将 vendor 添加到您的 .gitignore 以避免将所有 gem 库都包含在“新文件”列表中。
