Answer 1

即使按照@ProperSharp 的建议运行sudo bundle install 应该有所帮助，但它并没有解决问题的原因。问题的原因是您当前的用户没有权限。最有可能到 rvm 或 rvm 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。
