osx – -bash：export：`=’：不是有效的标识符

每次我打开我的终端，我会得到bellow错误：

-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

这里是我的出口产出：

当您执行以下操作时，不能在空格周围放置空格：

export foo=bar

删除你拥有的空间，你应该很好去。

如果输入：

export foo = bar

shell将解释为导出三个名称的请求：foo，=和bar。 =不是有效的变量名，所以命令失败。变量名称等号，它的值不能由空格分隔，以便作为同时分配和导出处理。
