-bash:导出:`=':不是有效的标识符 [英] -bash: export: `=': not a valid identifier

问题描述

每次打开终端时，都会出现以下错误:

Every time I open my terminal I get the error below:

Last login: Sun Aug  4 17:23:05 on ttys000
-bash: export: `=': not a valid identifier
-bash: export: `/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/local/mysql/bin': not a valid identifier
-bash: export: `=': not a valid identifier
-bash: export: `/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/local/mysql/bin': not a valid identifier

这是我的export输出:

推荐答案

这样做时，您不能在=符号周围放置空格:

You cannot put spaces around the = sign when you do:

export foo=bar

删除您拥有的空间，您应该会很好.

Remove the spaces you have and you should be good to go.

如果您输入:

export foo = bar

外壳程序会将其解释为输出三个名称的请求:foo，=和bar. =不是有效的变量名，因此命令失败.变量名称，等号，其值不能用空格分隔，以便将它们作为同时赋值和导出处理.

the shell will interpret that as a request to export three names: foo, = and bar. = isn't a valid variable name, so the command fails. The variable name, equals sign and it's value must not be separated by spaces for them to be processed as a simultaneous assignment and export.
