You are using the wrong syntax. Drop the spaces:
您使用了错误的语法。删除空格：
export PATH=$PATH:/home/username/foo
Regarding /etc/login.defsor any other global configuration: Well, it is global configuration, so probably a bad idea to add paths within your $HOMEdirectory there. ;)
关于/etc/login.defs或任何其他全局配置：嗯，这是全局配置，因此在您的$HOME目录中添加路径可能是个坏主意。;)

There are differences in syntax between the one used on mac and CentOS, however on CentOS and RedHat the following syntax is being used.
在 mac 和 CentOS 上使用的语法之间存在差异，但是在 CentOS 和 RedHat 上使用以下语法。
export PATH="/path/directory:$PATH"then do
source .bashrc
export PATH="/path/directory:$PATH"然后做
source .bashrc
I am not sure about other distributions of Linux but it will work on CentOS and RedHat.
我不确定 Linux 的其他发行版，但它可以在 CentOS 和 RedHat 上运行。
