Gemfile.lock写错误,权限？

Question

我不久前创建了一个Rails模型"模型",现在我正在尝试运行服务器.之后bundle install,我得到:

尝试写入Gemfile.lock时出错.您可能需要在路径中允许对文件的写权限:/home/thiago/model/Gemfile.lock

试图rails s看看会发生什么,并:

/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,以便捆绑和运行服务器吗？

模型文件创建错误？

Answer 1

您的应用程序根目录(其权限管理文件创建)和文件都由root而不是您的用户拥有(可能是因为您没有sudo rails new使用sudo它).您可以通过执行以下操作更改权限:

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

"myappfolder"是你的Rails应用程序的根目录.

顺便说一句,关于的一个好的提示sudo是总是在没有它的情况下首先尝试命令,然后,如果运行时存在权限错误,则可能需要sudo.不要默认使用sudo.

Answer 2

有时上面的答案是：

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

会给你错误：

chown: ifeegoo: illegal group name

你也可以试试这样的命令：

sudo chown -R ifeegoo: /Users/ifeegoo/workspace/rails/Test
