在MAC的终端窗口中加载MySql会引发错误“无效标识符”

Question

在Mac上安装并启动MySQL之后，尽管我键入以下代码以使系统知道其保存位置，但我无法使终端识别mysql：

$ echo 'export PATH=/usr/local/mysql/bin:$PATH' >> ~/.bash_profile

$ . ~/.bash_profile

-bash: export: `=': not a valid identifier
-bash: export: `/usr/local/mysql/bin:/usr/local/mysql/bin:/usr/local/mysql/bin:/usr/local/mysql/bin:/local/mysql/bin:/usr/local/mysql/bin:/usr/local/mysql/bin:/usr/local/mysql/bin:/usr/local/mysql/bin:PATH:/usr/local/mysql/bin': not a valid identifier
-bash: export: `=': not a valid identifier
-bash: export: `/usr/local/mysql/bin:/usr/local/mysql/bin:/usr/local/mysql/bin:/usr/local/mysql/bin:/local/mysql/bin:/usr/local/mysql/bin:/usr/local/mysql/bin:/usr/local/mysql/bin:/usr/local/mysql/bin:PATH:/usr/local/mysql/bin': not a valid identifier
-bash: export: `=': not a valid identifier
-bash: export: `/usr/local/mysql/bin:/usr/local/mysql/bin:/usr/local/mysql/bin:/usr/local/mysql/bin:/local/mysql/bin:/usr/local/mysql/bin:/usr/local/mysql/bin:/usr/local/mysql/bin:/usr/local/mysql/bin:PATH:/usr/local/mysql/bin': not a valid identifier
-bash: export: `=': not a valid identifier
-bash: export: `/usr/local/mysql/bin:/usr/local/mysql/bin:/usr/local/mysql/bin:/usr/local/mysql/bin:/local/mysql/bin:/usr/local/mysql/bin:/usr/local/mysql/bin:/usr/local/mysql/bin:/usr/local/mysql/bin:PATH:/usr/local/mysql/bin': not a valid identifier

我会很想念我，
