问题描述

如何查找已安装的 node.js/npm 包的版本?

How to find the version of an installed node.js/npm package?

这会打印 npm 本身的版本:

This prints the version of npm itself:

npm -v <package-name>

这会打印一个神秘的错误:

This prints a cryptic error:

npm version <package-name>

这会在注册表上打印软件包版本(即可用的最新版本):

This prints the package version on the registry (i.e. the latest version available):

npm view <package-name> version

我如何获得安装版本?

推荐答案

npm list 用于本地包或 npm list -g 用于全局安装的包.

npm list for local packages or npm list -g for globally installed packages.

您可以通过将名称作为参数传递来查找特定包的版本.例如，npm list grunt 将导致:

You can find the version of a specific package by passing its name as an argument. For example, npm list grunt will result in:

projectName@projectVersion /path/to/project/folder
└── grunt@0.4.1

或者，您可以只运行 npm list 而不将包名称作为参数传递来查看所有包的版本:

Alternatively, you can just run npm list without passing a package name as an argument to see the versions of all your packages:

├─┬ cli-color@0.1.6 
│ └── es5-ext@0.7.1 
├── coffee-script@1.3.3 
├── less@1.3.0 
├─┬ sentry@0.1.2 
│ ├── file@0.2.1 
│ └── underscore@1.3.3 
└── uglify-js@1.2.6 

您还可以添加 --depth=0 参数以列出已安装的软件包，而无需它们的依赖项.

You can also add --depth=0 argument to list installed packages without their dependencies.
