解決方案
1.安裝node-gyp
npm install -g node-gyp
2.安裝python
推薦安裝2.7版本（自行選擇32位或者64位安裝）：
https://www.python.org/downlo...
如果官網下載速度很慢，可以使用另一種安裝方式
以管理員身份執行
npm install --global --production windows-build-tools
安裝完成后會在C:WindowsSystem32里找到一個名為.windows-build-tools的文件夾
可以直接按照這個目錄配置環境，為了方便，我選擇將python27重裝到D盤，點擊python-2.7.15.amd64.msi選擇
移除之后再點擊setup程序，這次可以直接安裝
安裝成功后，在命令行界面輸入python測試是否安裝成功
3.配置環境變量
環境變量->系統環境變量->Path
4.npm 配置
npm config set python "D:\Python27\python.exe" npm config set node_gyp "D:\nodejs\node_modules\npm\node_modules\node-gyp\bin\node-gyp.js"
配置成功后，再次運行npm install就不會報錯了
