如何本地 npm 安装从 github 上面下载的开源包。

npm install username/reponame

可以用镜像

npm install <folder>:

Install the package in the directory as a symlink in the current project. Its dependencies will be installed before it's linked. If <folder> sits inside the root of your project, its dependencies may be hoisted to the toplevel node_modules as they would for other types of dependencies.

npm install <tarball file>:

Install a package that is sitting on the filesystem. Note: if you just want to link a dev directory into your npm root, you can do this more easily by using npm link.

Tarball requirements:

The filename must use .tar, .tar.gz, or .tgz as the extension.
The package contents should reside in a subfolder inside the tarball (usually it is called package/). npm strips one directory layer when installing the package (an equivalent of tar x --strip-components=1 is run).
The package must contain a package.json file with name and version properties.

Example:

npm install ./package.tgz

package.json 文件中可以使用 file: 前缀的方式加载本地的包，第三方包就是这样开发测试的

@Jirajine 谢谢回复,我试一下

@yuang 谢谢回复,我试一下

@wisunny 这个要具体怎么操作呢?

@Rhianu 看不懂

@ZhouWenhao529 https://developer.aliyun.com/mirror/NPM

package.json 也可以加载 github 的文件，推荐的应该是用阿里的镜像

@renmu123 谢谢回答,我试试

npm install github:Medium/phantomjs-prebuilt

这样可以嘛？
不过好像这个库已经处于废弃状态了

@retanoj 是的,这是一个旧的代码

直接复制或链接到你的 node_modules 里就可以了。

在你项目目录里
```
# 确保下载的包目录名字为 phantomjs-prebuilt
# 直接复制到 node_modules 里
cp -r 你下载包的位置 /phantomjs-prebuilt ./node_modules/

# 安装依赖
npm i
```

不过有可能其他包也下不下来，这种情况要么挂代理，要么用 cnpm （淘宝源）吧。
