英文:
Cannot edit .profile on Mac OS Catalina
问题
我想在Mac的/etc文件夹中的.profile中声明$JAVA_HOME。我使用chmod 777 profile赋予了它权限，但它仍然不允许我进行编辑。
我对在Mac上进行开发还不熟悉。
以下是我收到的错误信息：
英文:
I wanted to declare $JAVA_HOME in .profile in /etc folder for Mac. I gave it permission using chmod 777 profile still it doesn't let me edit it.
I am new to development in mac.
Following is the error I get

尝试从您的用户中编辑.profile文件，而不是在/etc目录下编辑（要编辑后者，您需要sudo权限，即使您编辑了它，很可能也不会被正确读取）。
因此，作为常规用户（非sudo），打开您的用户中的.profile文件。使用open命令（如您的屏幕截图中所示，但我更推荐选择vim）。以下其中一个命令应该有效：
open ~/.profile
或者
open /Users/${your-username}/.profile
我猜${your-username}是divya，所以完整的路径应该是：
open /Users/divya/.profile
如果您收到错误消息说“文件/.../.profile不存在”，首先创建一个空文件：
touch ~./profile
在.profile文件中添加以下行：
export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_202.jdk/Contents/Home
（确保使用安装在您的机器上的Java版本）
然后，要使更改生效，重新启动终端窗口，或者输入：
source ~/.profile
为了验证是否正确设置了$JAVA_HOME：
echo $JAVA_HOME
接着输入：
java -version
英文:
Try to edit the .profile from your user, and not the one under /etc (to edit that one you need sudo rights, and even if you do edit it, most probably it won't be read correctly).
So, as a regular user (not sudo), open the one from your user. Using open (as in your screenshot, but I would rather choose vim). One of the below commands should work:
open ~/.profile
or
open /Users/${your-username}/.profile
I guess ${your-username} is divya, so the complete path would be:
open /Users/divya/.profile
If you get an error saying The File /.../.profile does not exist, first create an empty one:
touch ~./profile
Add in the .profile file, the following line:
export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_202.jdk/Contents/Home
(make sure to use the Java version installed on your machine)
Then, for the changes to take place, either restart your terminal window, or type:
source ~/.profile
And to validate that you've set the $JAVA_HOME correctly:
echo $JAVA_HOME
Followed by:
java -version
