在命令前键入 SUDO。

您遇到权限错误。

尽管 运行 sudo bundle install 应该按照@ProperSharp 的建议提供帮助,但它并没有解决问题的根源。问题的原因是您当前的用户没有权限。最有可能到 rvmrvm 的 gemset 文件夹。 RVM 期望当前用户拥有 gem 目录。

您需要找到该文件夹​​并chown它。或者,使用以下 RVM 命令为您执行此操作:

# General environment repairs
rvm repair

# Fixes issues with folder/file permissions
rvm fix-permissions

第二个命令应该有帮助。
