我写了我的第一个node.js应用程序,但它找不到快递库:

C:\ChatServer\Server>node server.js

module.js:340
    throw err;
          ^
Error: Cannot find module 'express'
    at Function.Module._resolveFilename (module.js:338:15)
    at Function.Module._load (module.js:280:25)
    at Module.require (module.js:364:17)
    at require (module.js:380:17)
    at Object.<anonymous> (C:\ChatServer\Server\server.js:6:9)
    at Object.<anonymous> (C:\ChatServer\Server\server.js:25:4)
    at Module._compile (module.js:456:26)
    at Object.Module._extensions..js (module.js:474:10)
    at Module.load (module.js:356:32)
    at Function.Module._load (module.js:312:12)

但快递被挂了(带-g钥匙):

C:\ChatServer\Server>npm install -g express
npm http GET https://registry.npmjs.org/express
npm http 304 https://registry.npmjs.org/express

我已经使用此帖子中的说明为node.js安装了NVM:

当我在节点版本之间切换然后使用npm来安装模块时,所有模块都放在同一个'node_modules'文件夹(〜/ node_modules /)中,而不是放在特定于该节点版本的'node_modules'目录中？

关于如何解决这个问题的任何想法？

当我试图运行nodeJS文件时,我的Ubuntu机器出现以下错误

node.js:201
        throw e; // process.nextTick error, or 'error' event on first tick
              ^
Error: Cannot find module 'mkdirp'
    at Function._resolveFilename (module.js:332:11)
    at Function._load (module.js:279:25)

    at require (module.js:370:17)

    at Module.load (module.js:348:31)
    at Function._load (module.js:308:12)
    at Module.require (module.js:354:17)

所以我试过 npm install mkdirp

npm http GET https://registry.npmjs.org/mkdirp

npm ERR! Error: failed to fetch from registry: mkdirp

我有一个 API，它发送具有以下标头的响应：

我想下载附件文件'Report.Csv'

谁能建议我如何通过脚本或纽曼做到这一点
