Liferay 7.1 主题创建：命令失败：C:\Windows\system32\cmd.exe /s /c "yo "--version""

问题描述

我正在尝试在 Lifray 7.1 上使用 yo 主题生成器生成主题。我按照以下链接中的步骤操作，我的问题是在运行此命令“npm install -g yo”时无法正确安装 yo。不知道为什么？！但这就是我得到的：

    C:\Windows\system32>npm install --global yo

解决方法

看起来你已经在 APPData 文件夹下安装了 node 和 npm。确保不要将其安装在 admin 或其他用户许可的文件夹或任何临时文件夹下。建议您将所有这些安装在特定的自定义文件夹路径中，其中 npm 依赖项安装命令不需要任何可能在您的情况下出现问题的权限。
