npm安装显示最新，而不是安装包

npm install package-name工作完美，但是当我在package.json文件中手动添加一个新的依赖（由通过git的拉动），然后尝试npm install只，它返回

up to date in 4.2 sec

而且不安装包。

仅供参考：我正在使用git来提取package.json文件。所以包名中没有任何问题。它只是不起作用，当我拉，并尝试仅与npm install安装它。

我的package.json是：

我遇到过这个问题，当我的立足之本 “现代的JavaScript” 跑export NODE_ENV=production。删除node_modules，的package.json，并清除缓存NPM没有解决这个问题后，我发现从这个计算器进入了答案：npm install won't install devDependencies

为了解决这个问题，我跑export NODE_ENV=可以除去生产标志。一旦我这样做了，我可以再次安装开发依赖项。希望这可以帮助。

我会检查并通知您。 – Aslam

正如@ j7an所说，问题必须取决于环境。我有同样的问题，我不知道我的NODE_ENV如何设置为生产。无论如何，我这样做：（在this answer解释）

删除package-lock.json
删除node_modules

之后：

npm install 
npm install --only=dev

这必须解决的问题。
