在Linux 用的好好的  npm install truffle-hdwallet-provider 或是   npm install zeppelin-solidity 因為合作的關係在千百個不願意還是換到了windows,在Windows 卻發生很多問題 : 以下是確認步驟: 1.記得要先設定git的環境變數 ex: C:\Program Files\Git\cmd 2.發現錯誤 npm ERR! git fetch -a origin (https://github.com/debris/bignumber.js.git) fatal: unable to access 'https://github.com/debris/bignumber.js.git/': Couldn't connect to server 此時先去更新git的版本 3.發現錯物 gyp ERR! node-gyp -v v3.6.2 gyp ERR! not ok 此時要更新 node-gyp  npm install -g node-gyp@latest 4. 發現錯誤  Can't find Python executable "python", you can set the PYTHON env varia ble. 此時要去安裝python ,但是自己安裝除除非很懂python ,不然這裡推薦一個方法 用管理員身分 執行 利用windows的 powershell 去執行以下這段command npm install --global --production windows-build-tools 所有插件一次安裝到好
