$USER != whoami

我正在尝试在我的 mac 上重新安装 homebrew。

我收到此错误：

michaels-1856:~ michael.snowden$ ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

michaels-1856:~ michael.snowden$

正是这一行让我烦恼：

chown: tomcat: illegal user name

我用谷歌搜索homebrew "the following directories will have their owner set to"，只找到一个搜索结果，那就是自制安装脚本

据我所知，我的用户名不是 tomcat。

具体来说，这是给我带来麻烦的脚本行：

"The following directories will have their owner set to #{Tty.underline 39}#{ENV['USER']}#{Tty.reset}:"

据我所知，问题是$USER=tomcat，但是whoami=michael.snowden

michaels-1856:~ michael.snowden$ whoami
michael.snowden
michaels-1856:~ michael.snowden$ echo $USER
tomcat

编辑 我在文件中发现的唯一引用~/.bash*“tomcat”的内容是我在创建这篇文章后查看 tomcat 是否是有效用户的操作。

michaels-1856:~ michael.snowden$ cat ~/.bash* | grep tomcat
chown tomcat test.txt

编辑 这个问题得到了解决，但该解决方案确实特定于我的计算机设置，并且需要进行大量挖掘。

显然，某些东西覆盖了 $USER 变量。您可以花几个小时尝试追溯可能导致此问题的原因，或者按顺序运行以下命令。

export USER=`whoami`
bash -x -c ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

如果再次发生这种情况，-x 标志将显示运行了哪些命令以及它们做了​​什么，包括初始化或修改的任何变量。它不会具体告诉您是什么原因导致这种情况发生，但它将有助于缩小范围，确定是源文件还是正在执行的 Ruby 文件的某些部分导致了这种情况。一路上会进行一些 grep 操作。
