在我做完之后它起作用了......
sudo chmod 1777 -R /home/rbtlong/.bundle/cache/compact_index
和
sudo chmod 1777 -R /tmp
答案 1 :(得分：3)
对我而言，它仅适用于777模式。所以我做了
sudo chmod 777 -R /home/<username>/.bundle/cache/compact_index
和
sudo chmod 777 -R /tmp
解释原因：它与Unix权限有关。您不能以超级用户（root）身份运行bundle，但bundle正在尝试写入用户必须是超级用户才能在其上写入的文件夹。 chmod 777 -R是一个命令，基本上说任何人（不仅是超级用户）都可以读取或写入该文件夹，对于没有-R参数的文件，你可以做同样的事情（这意味着递归）。

我必须先运行：
sudo rm -rf /home/<username>/.bundle/cache/compact_index/*
然后
sudo chmod 1777 -R /home/rbtlong/.bundle/cache/compact_index
sudo chmod 1777 -R /tmp

我不知道您是否通过以上某个答案找出了问题，但我遇到了同样的问题，并从this question发现Dir.foreach返回'.'和{ {1}}作为可枚举的一部分，您不能也不应该删除当前和父目录
答案 4 :(得分：0)
我通过关闭以管理员身份打开的Docker终端并在普通用户终端中运行服务器来解决了我的问题。不需要运行任何命令。
我在docker启用的Linux环境中运行此程序，因此，该解决方案可能对使用linux或docker的人有所帮助。
