npm 安装后 npm 缺少包

Question

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，无法添加 "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;
    ^

Answer 1

Supertest 在 devDependencies 中，如果你运行 npm install 带有标志 --production 或 NODE_ENV 等于 production 它不会被安装。您可以将其移动到 dependencies 或更改您的 NODE_ENV。您可以在 documentation
