环境：

Bundler 1.12.3
Rubygems 2.4.8
Ruby 2.2.3p173 (2015-08-18 revision 51636) [x86_64-linux]

Answer 1

我做了之后才工作......

sudo chmod 1777 -R /home/rbtlong/.bundle/cache/compact_index

和

sudo chmod 1777 -R /tmp

Answer 2

对我来说，它只适用于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参数可以执行相同操作的文件（这意味着递归）。

Answer 3

我不知道你是否用上述答案之一弄清楚了你的问题，但我有同样的问题，并从this question发现Dir.foreach返回'.'和'..'作为可枚举的一部分，你不能也不应该删除当前和父目录
