这似乎是我们在Update 6中引入的错误，如果您的npm安装目录（通常在您的AppData文件夹中）的路径在路径中有空格，则会导致npm install错误。简单的解决方法是更改​​您的npm安装目录：

This appears to be a bug that we introduced in Update 6 that causes npm install errors if the path to your npm install directory (usually in your AppData folder) has a space in the path. The simple workaround is to change your npm install directory:

npm config set prefixC：\Folder\With\No\Spaces

npm config set prefix "C:\Folder\With\No\Spaces"

然后在VS中再次构建。我们会尽快解决问题，并在更新7中发布。

And then build again in VS. We will get this fixed up and released in Update 7 as soon as we can.

对不便之处，不便之处，敬请见谅。

Sorry for the inconvenience.
