npm安装后npm缺less的包
我决定在远程机器上部署我的软件，但是当我开始“npm install”添加package.json的每个包时，不可能添加“supertest”包。 我尝试了很多方法来解决问题，删除node_modules并重新启动npm install两次，或者使用Yarn代替NPM。
$ npm install supertest + supertest@2.0.1 removed 13 packages and updated 3 packages in 2.28s api-http@remotemachine:~/api-http$ npm test > api-http@0.0.1 test /home/api-http/api-http > NODE_ENV=test mocha --recursive test module.js:487 throw err; ^ Error: Cannot find module 'supertest' at Function.Module._resolveFilename (module.js:485:15) at Function.Module._load (module.js:437:25) at Module.require (module.js:513:17) at require (internal/module.js:11:18) at Object.<anonymous> (/home/api-http/api-http/test/app/controllers/crop.js:3:17) at Module._compile (module.js:569:30) at Object.Module._extensions..js (module.js:580:10) at Module.load (module.js:503:32) at tryModuleLoad (module.js:466:12) at Function.Module._load (module.js:458:3) at Module.require (module.js:513:17) at require (internal/module.js:11:18) at /home/api-http/api-http/node_modules/mocha/lib/mocha.js:230:27 at Array.forEach (native) at Mocha.loadFiles (/home/api-http/api-http/node_modules/mocha/lib/mocha.js:227:14) at Mocha.run (/home/api-http/api-http/node_modules/mocha/lib/mocha.js:513:10) at Object.<anonymous> (/home/api-http/api-http/node_modules/mocha/bin/_mocha:480:18) at Module._compile (module.js:569:30) at Object.Module._extensions..js (module.js:580:10) at Module.load (module.js:503:32) at tryModuleLoad (module.js:466:12) at Function.Module._load (module.js:458:3) at Function.Module.runMain (module.js:605:10) at startup (bootstrap_node.js:158:16) at bootstrap_node.js:575:3 npm ERR!

devDependencies在devDependencies ，如果你用标志运行npm install --production或者NODE_ENV等于production它不会被安装。 您可以将其移至dependencies或更改您的NODE_ENV 。 你可以在文档中find更多关于它的信息
