无法在模拟器中启动AVD. sh:grep:找不到命令 [英] Cannot launch AVD in emulator. sh: grep: command not found
问题描述
在Android Studio中，启动AVD Manager，选择一个虚拟设备，然后单击播放"按钮将其启动.
In Android Studio, launch AVD Manager, I choose one of my virtual device and click Play button to start it.
然后我收到此错误消息
"Cannot launch AVD in emulator.
sh: file: command not found
sh: grep: command not found
... "
Then I get this error message
"Cannot launch AVD in emulator.
sh: file: command not found
sh: grep: command not found
... "
这一直很好，我想我可以通过运行以下命令弄乱PATH变量.
It's fine all the while and I think I mess up with the PATH variable by running the following command.
echo 'export PATH=/Users/xxx/Library/Android/sdk/tools' >> ~/.bash_profile
echo 'export PATH=/Users/xxx/Library/Android/sdk/platform-tools' >> ~/.bash_profile
执行完这些命令后，我也无法在终端中找到像ls这样的简单命令.
然后我通过运行来修复它
After executing these, I couldn't find simple command like ls in Terminal too.
Then I fixed it by running
PATH=/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin
之后，ls，grep等再次正常运行.
我在终端窗口中检查它，它显示相同的错误之前，运行上面的命令将其修复.
After that, ls, grep etc are working fine again.
I check it in the Terminal windows, it is showing the same error before, running the above command fixed it.
但是，当我尝试启动AVD时，它仍然失败，并显示上述错误消息. 尝试重新启动，使cahce无效，无济于事.
However, when I try to launch AVD, it still failed with the error message above. Try to restart, invalidate cahce, nothing help.
推荐答案
您设置的路径错误.实际上，您只是在替换它.您需要做的是添加到路径.像这样:
You are setting your path wrong. In fact you are just replacing it. What you need to do is to add to path. Like this:
echo 'export PATH=$PATH:/Users/xxx/Library/Android/sdk/platform-tools' >> ~/.bash_profile
确保在编辑器中查看〜/.bash_profile并删除以前的PATH条目.
Be sure to view ~/.bash_profile in editor and remove previous PATH entries.
请注意添加的$ PATH.这样，它将采用先前的路径并追加新的路径.
Note the added $PATH. This way it takes the previous path and appends the new one.
PATH=$PATH:your_path_here
