npm 6.3.0--仅=产品安装开发依赖性

将npm版本从5.6.0升级到6.3.0后，

--only=prod

参数不起作用，并且npm安装软件包也在devdependences中列出。但在5.6.0版本中，其工作原理与预期一致。在根文件夹中没有

package lock.json

的情况下继续安装

节点版本

8.11.3

npm版本

6.3.0

我在做一个角度的项目。下面是package.json文件：

我也有同样的问题——跑步

NODE\u ENV=生产npm安装

为我工作。

来自：

因此，请使用节点\u ENV ENV var或--production标志

With the --production flag (or when the NODE_ENV environment variable
is set to production),npm will not install modules listed in devDependencies.

NOTE: The --production flag has no particular meaning when adding a dependency
to a project
