错误：在结构 1.2 中找不到模块'cors'

Question

我收到错误：找不到模块"fabric-client"错误，然后手动运行"npm install"fabric-client@1.0.5'在node_module内，则我得到错误以下

[root@ip-172-31-61-27 controller]# node app.js module.js:538
throw err;
^
Error: Cannot find module 'cors'

at Function.Module._load (module.js:489:3)

我们已经在package.json文件中有一个"cors"条目，但它仍然给出了上面的错误。下面是package.json文件：-

{
"name": "awsnodeapp",
"version": "1.0.0",
"description": "",
"main": "index.js",
"scripts": {
"test": "echo "Error: no test specified" && exit 1"
},
"author": "",
"license": "ISC",
"dependencies": {
"aws-sdk": "^2.538.0",
"body-parser": "^1.17.1",
"cors": "^2.8.3",
"express": "^4.15.2",
"express-session": "^1.15.2",
"fabric-ca-client": "1.3.0",
"fabric-client": "1.3.0",
"fs-extra": "^2.0.0",
"log4js": "^3.0.6",
"uuid": "^3.3.2",
"ws": "^6.1.0"
}
}

Answer 1

由于app.js需要cors模块，因此需要安装并添加到package.json中。

npm install cors --save

你可以从这篇旧帖子中找到答案：错误：找不到模块'；cors'；
