Answer 1

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

(npm list用于本地软件包）或npm list -g用于全局安装的软件包）。)

You can find the version of a specific package by passing its name as an argument.

(您可以通过传递特定软件包的名称作为参数来查找其版本。)

For example, npm list grunt will result in:

(例如， npm list grunt将导致：)

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

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

(另外，您可以只运行npm list而不传递软件包名称作为参数来查看所有软件包的版本：)

├─┬ 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 

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

(您也可以添加--depth = 0以列出已安装的软件包，而无需依赖它们。)
