方式一：安裝python解決(正确配置系統環境變量)，python(v2.7 recommended, v3.x.x is not supported) - 推薦
下載下傳：http://www.python.org/ftp/python/2.7.3/python-2.7.3.msi
自行下載下傳
npm install --python=python2.7 #先下載下傳
npm config set python python2.7 #再設定環境
方式二：先用管理者身份打開cmd - 推薦
清除npm緩存 npm cache clean --force
1.安裝 npm install -g node-gyp
2.安裝 npm install --global --production windows-build-tools
-報錯加版本号
2.1 npm install --global --production [email protected]
預設安裝路徑npm install --python=python2.7npm config set python python2.7 如果不是預設安裝需要指定python位置：npm config set python phthon安裝路徑如npm config set python 'D:/python/python.exe' 
.windows-build-tools檔案夾中多了一些東西
解決
①執行npm指令npm install --global --production [email protected]
②當指令行界面開始不動時，打開任務管理器，把Build Tools結束任務（因為我沒有找到BuildTolls_Full.exe）。
③再打開.windows-build-tools檔案夾中的build-tools-log.txt，添加Variable: IsInstalled = 1，儲存，關閉。
再看PowerShell界面
