提问by sphaughton
recently on mac, i set an environment variable so that it is present in a new shell. today opening a shell it no longer appears in a new shell even when i set it. i have been using:
最近在 mac 上，我设置了一个环境变量，以便它出现在一个新的 shell 中。今天打开一个外壳，即使我设置了它，它也不再出现在新的外壳中。我一直在使用：
export "AVARIABLE=example" >>~/.bash_profile
which has worked fine until now when i run:
到目前为止，当我运行时一直运行良好：
echo $AVARIABLE
i just get a blank line as if it doesn't exist.
我只是得到一个空行，就好像它不存在一样。
this is happening any time i try to set an environment variable permanently now. i can't see what i'm doing wrong?
每当我尝试永久设置环境变量时，都会发生这种情况。我看不出我做错了什么？
thanks in advance

You are missing an echoin your command. Try this and and then source the ~/.bash_profile:
您echo的命令中缺少一个。试试这个，然后获取~/.bash_profile：
echo export "AVARIABLE=example" >> ~/.bash_profile
You also have to source the .profileafter you make changes to it.
您还必须.profile在对其进行更改后获取源。
source ~/.bash_profile
