npm install 报错 check python checking for Python executable python2 in the PATH

场景：在升级了node环境后项目发生了版本号不匹配报错，决定重新初始化后又有了一下报错

在网上搜索的解决方案是：

npm install --global windows-build-tools --save

但是在安装windows-build-tools时卡住了，于是解决方案如下

1、运行npm install -g windows-build-tools
2、在%temp%文件夹中找到最新的文件名类似于dd_installer_20210421124746.log的文件
3、查看此文件，确保日志中输出了Closing the installer with exit code 0
4、确保你安装了vscode
ps:其实可以直接跳过2–4步，因为你的python环境早就安装好了，重复的步骤安装程序早就执行完毕了
5、在%temp%目录下创建一个名为dd_client_.log的文件
6、编辑5中创建的文件，加入一行Closing installer. Return code: 3010.然后保存。
注：直接在资源管理器中粘贴%temp%即可打开你的Windows temp目录。

最终npm install安装成功
