你如何防止安装“devDependencies"?Node.js (package.json) 的 NPM 模块? [英] How do you prevent install of "devDependencies" NPM modules for Node.js (package.json)?

问题描述

我的 package.json 文件中有这个(缩短版):

I have this in my package.json file (shortened version):

{
  "name": "a-module",
  "version": "0.0.1",
  "dependencies": {
    "coffee-script":      ">= 1.1.3"
  },
  "devDependencies": {
    "stylus":             ">= 0.17.0"
  }
}

我在 Mac 10.6.8 上使用 NPM 版本 1.1.1.

I am using NPM version 1.1.1 on Mac 10.6.8.

当我从项目根目录运行以下命令时，它会安装 dependencies 和 devDependencies:

When I run the following command from the project root, it installs both the dependencies and devDependencies:

npm install

我的印象是这个命令安装了devDependencies:

I was under the impression that this command installed the devDependencies:

npm install --dev

我如何做到这样 npm install 只安装 dependencies(所以生产环境只安装那些模块)，而像 npm install --dev 安装 dependencies 和 devDependencies?

How do I make it so npm install only installs dependencies (so production environment only gets those modules), while something like npm install --dev installs both dependencies and devDependencies?

推荐答案

npm install 命令将安装 devDependencies 和其他 dependencies在包目录中运行，在开发环境中(默认).

The npm install command will install the devDependencies along other dependencies when run inside a package directory, in a development environment (the default).

使用npm install --only=prod(或--only=production)安装only dependencies，而不是 devDependencies，无论 NODE_ENV 环境变量的值如何.

Use npm install --only=prod (or --only=production) to install only dependencies, and not devDependencies, regardless of the value of the NODE_ENV environment variable.

注意:您可能还需要--no-optional

注意:在npm (2015-08-13) v3.3.0之前，该选项被称为--production，即npm install --production.

Note: Before v3.3.0 of npm (2015-08-13), the option was called --production, i.e. npm install --production.
