尝试在Windows

Question

我在Windows上，正在尝试按照http://yeoman.io/learning/index.html的说明操作。到目前为止，我已经成功安装了grunt-cli和bower但是当我尝试使用以下命令安装你时...

npm install -g yo

...命令提示符返回：

> node postinstall

有谁知道这到底意味着什么以及如何解决它？

Answer 1

您可以尝试使用此功能：https://github.com/npm/npm/issues/7781

我认为这有助于您解决问题。

获得节点＆amp; npm in cmd。您可以在Windows环境变量中设置节点位置。然后重启你的cmd＆amp;再试一次。

Answer 2

尝试使用功能npm软件包管理器重新安装安装程序，然后返回到npm安装。
