npm 6.3.0 --only=prod install devDependencies also

Question

将npm版本从5.6.0升级到6.3.0后，--only=prod参数不起作用，npm也安装devDependencies中列出的软件包。 但是在 5.6.0 版本中，它按预期工作。安装继续，无需在根文件夹中package-lock.json

节点版本8.11.3npm 版本6.3.0

我正在从事Angular项目。这是package.json文件：

Answer 1

我遇到了同样的问题 - 运行

NODE_ENV=production npm install

为我工作。

Answer 2

来自 npmjs 文档：

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

因此，请使用NODE_ENV env var或 --production标志。

Answer 3

使用

--only=production

或

--omit=dev
