　　下载：http://www.python.org/ftp/python/2.7.3/python-2.7.3.msi
　　自行下载
　　npm install --python=python2.7 #先下载
　　npm config set python python2.7 #再设置环境方式二：先用管理员身份打开cmd - 推荐
　　清除npm缓存 npm cache clean --force
　　1.安装 npm install -g node-gyp
　　2.安装 npm install --global --production windows-build-tools
　　-报错加版本号
　　2.1 npm install --global --production windows-build-tools@4.0.0默认安装路径npm install --python=python2.7npm config set python python2.7  如果不是默认安装需要指定python位置：npm config set python phthon安装路径如npm config set python ＂D:/python/python.exe＂
　　.windows-build-tools文件夹中多了一些东西
　　解决
　　①执行npm命令npm install --global --production windows-build-tools@4.0.0
　　②当命令行界面开始不动时，打开任务管理器，把Build Tools结束任务（因为我没有找到BuildTolls_Full.exe）。
　　③再打开.windows-build-tools文件夹中的build-tools-log.txt，添加Variable: IsInstalled = 1，保存，关闭。
　　再看PowerShell界面
