如题：名字无所谓啦！
具体就是在项目升级到Ionic3之后，通过命令行安装插件，例如：
cordova plugin add https://github.com/xxxxxx or ionic
cordova plugin add https://github.com/xxxxxx
时候报错信息如下：
0 info it worked if it ends with ok 1 verbose cli [ 'E:\\Program Files\\nodejs\\node.exe', 1 verbose cli 'C:\\Users\\xxx\\AppData\\Roaming\\npm\\node_modules\\npm\\bin\\npm-cli.js', 1 verbose cli 'install', 1 verbose cli 'https://github.com/xxx', 1 verbose cli '--save' ] 2 info using [email protected] 3 info using [email protected] 4 verbose npm-session e0c46567e228ed06 5 silly install loadCurrentTree 6 silly install readLocalPackageData 7 silly fetchPackageMetaData error for git+https://github.com/hewz/cordova-baidu-location.git Error while executing: 7 silly fetchPackageMetaData C:\Program Files\Git\cmd\git.EXE ls-remote -h -t https://github.com/xxx.git 7 silly fetchPackageMetaData 7 silly fetchPackageMetaData fatal: Unable to find remote helper for 'https' 7 silly fetchPackageMetaData 7 silly fetchPackageMetaData exited with error code: 128 8 verbose stack Error: exited with error code: 128 8 verbose stack at ChildProcess.onexit (C:\Users\Roronoazoro\AppData\Roaming\npm\node_modules\npm\node_modules\mississippi\node_modules\end-of-stream\index.js:39:36) 8 verbose stack at emitTwo (events.js:125:13) 8 verbose stack at ChildProcess.emit (events.js:213:7) 8 verbose stack at Process.ChildProcess._handle.onexit (internal/child_process.js:200:12) 9 verbose cwd C:\Users\Roronoazoro\lj3\node_modules 10 verbose Windows_NT 10.0.15063 11 verbose argv "E:\\Program Files\\nodejs\\node.exe" "C:\\Users\\Roronoazoro\\AppData\\Roaming\\npm\\node_modules\\npm\\bin\\npm-cli.js" "install" "https://github.com/hewz/cordova-baidu-location" "--save" 12 verbose node v8.2.1 13 verbose npm v5.3.0 14 error Error while executing: 14 error C:\Program Files\Git\cmd\git.EXE ls-remote -h -t https://github.com/hewz/cordova-baidu-location.git 14 error 14 error fatal: Unable to find remote helper for 'https' 14 error 14 error exited with error code: 128 15 verbose exit [ 1, true ]
大致意思呢就是不支持或者找不到“https”这个协议；
解决方案为：设置GIT环境变量，
特此说明：GIT安装后默认会在PATH下面设置环境变量，但是默认的是git目录下的cmd目录，此时安装插件就会报错如上信息，把环境变量 重置为git目录下的bin目录即可。问题解决！
