不久前我创建了一个 Rails 模型“模型”，现在我正在尝试运行服务器。在 bundle install 之后，我得到:

There was an error while trying to write to Gemfile.lock. It is likely that you need to allow write permissions for the file at path: /home/thiago/model/Gemfile.lock

试过 rails s 看看会发生什么，然后:

/home/thiago/.rvm/gems/ruby-1.9.3-p429/gems/bundler-1.3.5/lib/bundler/definition.rb:235:in `rescue in lock': There was an error while trying to write to Gemfile.lock. It is likely that  (Bundler::InstallError)
you need to allow write permissions for the file at path:

我可以设置 Gemfile.lock 的权限，以便我可以 bundle 和运行服务器吗？

模型文件创建不正确？

最佳答案

您的应用根目录(其权限控制文件创建)和文件都归 root 而不是您的用户所有(可能是因为您使用了 sudo rails new——不要使用 sudo 为此)。您可以通过以下方式更改权限:

sudo chown -R $(whoami):$(whoami) myappfolder

其中“myappfolder”是 Rails 应用的根目录。

顺便说一句，关于 sudo 的一个好技巧是总是先尝试没有它的命令，然后，如果在运行时出现权限错误，您可能需要 sudo。不要默认使用 sudo。
