npm 安装多个包名

Question

当我运行这个命令时它做了什么：

npm install --save-dev package1 package2

绝对不是安装多个包，但看起来是必不可少的。（例如https://www.browsersync.io/docs/gulp）

对我来说，它抛出以下错误：

Answer 1

It is definitely not installing multiple packages

为什么？您正在安装 package1 和 package2 并将它们标记为 devDependencies 和 --save-dev.

如the documentation所述，您可以组合多个参数，甚至多种类型的参数。在您的例子中，您组合了在注册表中发布的 2 个包名称。

Answer 2

另存为依赖项：

npm i package1 package2

另存为开发依赖项：

npm i -D package1 package2

npm i --save-dev package1 package2

Answer 3

npm install -save module1 module2

示例： npm install -save morgan chalk errorhandler lusca dotenv 路径 mongoose

以上命令将安装最新版本的 morgan、chalk、errorhandler、lusca、dotenv、path 和 mongoose。

Answer 4

此处的其他答案似乎没有回答问题。具体来说，执行 npm install --save-dev p1 p2 p3 不会导致 p2 和 p3 存储在我的 package.json 文件中。

以下行为我安装所有包+将其保存在开发依赖项中：

for i in 'package1' 'package2'; do npm install --save-dev "$i"; done

我在 Windows 上使用 Cygwin，但这也适用于 *nix 系统。

有点不相关，但如果使用 Cygwin 则非常重要：如果你使用 Cygwin，you need to add noacl 到你的挂载选项，否则它会弄乱你的模块权限并导致 Windows吓坏了。
