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

Question

我正在尝试使用 Lifray 7.1 上的 yo 主题生成器生成主题。我按照下面链接上的步骤操作，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

Answer 1

我已经解决了这个问题。需要安装老版本的yoaman，

我相信命令是这样的：

npm install -g yo@3.x

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管理员或其他用户许可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的权限。
