如何在 Mac 上恢复 .bash_profile?我的 unix 终端都没有工作

我在尝试将 Playframework 添加到我的路径时向我的 bash_profile 添加了一些东西，但有些东西搞砸了.

I added something to my bash_profile while trying to add Playframework to my path and something got messed up badly.

我将以下行添加到我的 .bash_profile

I added the following line to my .bash_profile

export PATH=$PATH:the path to my play excitable 

然后我保存了所有内容并重新启动了我的终端.我不能再从我的终端做任何事情.我无法 cd 进入任何目录，我再也找不到 java，我无法打开 vi 或 nano.我发现 这个 SuperUser 上的帖子建议打开一个不同的终端并更改 bash 配置文件.

then I saved everything and restarted my terminal. I can no longer do anything from my terminal. I can't cd into any directory, I can no longer find java, I can't open vi or nano. I found this thread on SuperUser that suggested opening a different terminal and changing the bash profile.

我尝试通过键入打开 bash

I tried opening bash by typing

/bin/bash

我成功地打开了另一个终端，但我仍然无法访问任何常规的 unix 命令.我仍然无法打开 vi 或 nano 来删除导致问题的行.

and I was successfully able to open another terminal but I still don't have access to any of the regular unix commands. I still wasn't able to open vi or nano to remove the line that is causing the problem.

我尝试下载新的终端应用程序，但没有成功.

I tried downloading a new terminal application without any luck.

我尝试打开隐藏文件，以便我可以通过运行以下命令使用文本编辑器更改文件:

I tried turning on hidden files so that I can just change the file with a text editor by running the following command:

defaults write com.apple.finder AppleShowAllFiles TRUE

但由于我的终端不工作，所以也不起作用.

but since my terminal isn't working that didn't work either.

我该如何修理我的电脑.
