• 今天在進行renren-fast前端部署的時候，執行npm install後失敗，出錯如下：

• 從上面看這句話Can't find Python executable "python", you can set the PYTHON env variable.，看了部落格知道是少了python2.7這個環境，所以下載python2.7，並且配置了環境變數，下載和安裝python2.7我是看了這位老哥的部落格。https://blog.csdn.net/u013925378/article/details/83210779
• 安裝完後，我開心地又執行了一遍npm install，果然事情沒有這麼簡單，又報了下面的錯誤。

• 看了上述的報錯，簡單地看（

F:\vscode\workrome\renren\renren-fast-vue\node_modules\node-sass\build\src\libsass.vcxproj(20,3): error MSB4019: 未找到匯入的專案“F:\Microsoft.Cpp.Default.props”。
請確認 <Imp

），就是少了這個檔案，裂開了，我的資料夾根本就沒有這個檔案，怎麼搞，有查了一下部落格，明白了，這個是因為被牆了，檔案下載不下來，還就直接報錯，所以整了一下，就決定用cnpm install來安裝依賴，安裝cnpm百度一堆部落格，我這裡就不講了，我直接就cnpm install,大功告成。

• 以上問題就是我自己遇到的，可能並不適合每一個人，希望對需要的人有幫助。
