如何全局安装节点模块？

Question

I have zero experience with npm other than knowing it exists. I believe I have managed to install uglify, but I have no idea how to use it. I had until recently been using Yuicompressor which had a java cli. How can I do something similar with uglify on a Windows 7 environment?

Unless there is a step I skipped, the command line tools details the arguements, but my attempts to try such fail.

'uglify' is not recognized as an internal or external command,
operable program or batch file.

Anyone care to advise?

Answer 1

To run it from the command line, you have to install it globally

C:\Data\Websites\local\htdocs\b>npm install uglify-js -g

Also, the name of the executable is uglifyjs

C:\Data\Websites\local\htdocs\b>uglifyjs

Answer 2

Even though you installed the package uglify-js, to actually use it, it is: uglifyjs. So using your example, it would be something like:

C:\Data\Websites\local\htdocs\b>uglifyjs [ options... ] [ filename ]

Where options are parameters like: --compress , and a filename would be whatever JS file you want to uglify. eg uglifyjs --compress --mangle -- input.js

Answer 3

存储库的自述文件中有一个“用法”部分。

uglifyjs [ options... ] [ filename ]
