问题描述

我有 npm v 1.2.32

I have npm v 1.2.32

当我运行时:$npm install mongo-migrate

When I run: $npm install mongo-migrate

它不安装 mongodb，这是一个 devDependency.

it does not install mongodb which is a devDependency.

我做错了什么?

推荐答案

当您从 NPM 存储库安装包时，不会自动安装开发依赖项(因为这些依赖项不是获取主要的依赖项所必需的)包工作正常).

When you install a package from the NPM repository, dev dependencies won't automatically be installed as well (because those dependencies shouldn't be necessary to get the main package working properly).

您还需要明确指示 npm 安装开发依赖项:

You need to explicitly instruct npm to install dev dependencies too:

npm install mongo-migrate --dev

更新

--dev 命令已被弃用.

npm WARN install 不推荐使用 --dev 选项.改用 --only=dev.

npm WARN install Usage of the --dev option is deprecated. Use --only=dev instead.

npm install mongo-migrate --only=dev
