我想这个答案有点迟了.

I guess this answer is a tad late.

您的问题是vscode在您的react-native的PATH引用上找不到.

Your problem is that vscode could not find on your PATH references of react-native.

如果您是使用npm安装的，请尝试以下操作:

If you installed it using npm try the following:

npm install react-native --global

npm install react-native --global

这应该将其安装在您的路径中.重新启动vscode，您应该一切顺利.

This should install it in your path. Restart vscode and you should be good to go.
