Node.js使用python安装ws错误

Question

安装了python 3.5.0版本（感谢Hiren S.），因为我没有安装它。 现在，当我尝试安装ws（Web套接字）时遇到此错误。仍然不知道我遇到了什么错误或这意味着什么。

Answer 1

您没有安装Python或未设置PYTHON环境变量。

您必须从此处下载python： https : //www.python.org/downloads/

Answer 2

Python 2.7版可与Node js（而非3.xx版）一起使用。 尝试安装此版本：2.7.11。 然后检查Python的路径：C：\\ Python27 \\和C：\\ Python27 \\ Scripts

然后以管理员身份在命令中运行npm install --global --production Windows-build-tools
