配置 npm 国内镜像仓库
$ yarn config set registry https://registry.npm.taobao.org --global
yarn config v1.22.4
success Set "registry" to "https://registry.npm.taobao.org".
Done in 0.04s.
$ yarn config set disturl https://npm.taobao.org/mirrors/node --global
yarn config v1.22.4
success Set "disturl" to "https://npm.taobao.org/mirrors/node".
Done in 0.03s.
$ yarn config get registry
https://registry.npm.taobao.org
$ yarn config get disturl
https://npm.taobao.org/mirrors/node
配置 node-sass 等使用国内镜像
$ vi .npmrc
sass_binary_site=https://npm.taobao.org/mirrors/node-sass/
phantomjs_cdnurl=https://npm.taobao.org/mirrors/phantomjs/
electron_mirror=https://npm.taobao.org/mirrors/electron/
sharp_dist_base_url=https://npm.taobao.org/mirrors/sharp-libvips/v8.9.1/
使用 yalc 发布本地版本
安装 yalc：
$ sudo yarn global add yalc
从 github 克隆相应的 npm 包到本地，并使用 yalc 进行本地发布：
$ ls
cwebp-bin mozjpeg-bin pngquant-bin
$ cd cwebp-bin/
$ yalc publish
cwebp-bin@5.1.0-dce829b8 published in store.
$ cd ../mozjpeg-bin/
$ yalc publish
mozjpeg@6.0.1-10b1648e published in store.
$ cd ../pngquant-bin/
$ yalc publish
pngquant-bin@5.0.2-f80f7246 published in store.
yalc 实际上是将 npm 包拷贝到了 ~/.yalc 目录：
$ yalc dir
/home/runsisi/.yalc
$ tree -L 4 $(yalc dir)
/home/runsisi/.yalc
└── packages
├── cwebp-bin

11 directories, 18 files
注意拷贝相应的可执行文件到 vendor 目录，否则仍然会连接 github 进行下载（阅读 lib 目录下的源码可知）：
$ cd ..
$ mkdir ~/.yalc/packages/cwebp-bin/5.1.0/vendor
$ cp cwebp-bin/vendor/linux/x64/cwebp ~/.yalc/packages/cwebp-bin/5.1.0/vendor/
$ mkdir ~/.yalc/packages/mozjpeg/6.0.1/vendor
$ cp mozjpeg-bin/vendor/linux/cjpeg ~/.yalc/packages/mozjpeg/6.0.1/vendor/
$ cp pngquant-bin/vendor/linux/x64/pngquant ~/.yalc/packages/pngquant-bin/5.0.2/vendor/
在实际的工程中添加 yalc 发布的本地 npm 包：
$ cd runsisi.github.io/
$ yalc add cwebp-bin mozjpeg pngquant-bin
Package mozjpeg@6.0.1-10b1648e added ==> /home/runsisi/working/src/runsisi.github.io/node_modules/mozjpeg.
Package pngquant-bin@5.0.2-f80f7246 added ==> /home/runsisi/working/src/runsisi.github.io/node_modules/pngquant-bin.
Package cwebp-bin@5.1.0-dce829b8 added ==> /home/runsisi/working/src/runsisi.github.io/node_modules/cwebp-bin.
Don't forget you may need to run yarn after adding packages with yalc to install/update dependencies/bin scripts.
$ yalc installations show
Installations of package cwebp-bin:
/home/runsisi/working/src/runsisi.github.io
Installations of package mozjpeg:
/home/runsisi/working/src/runsisi.github.io
Installations of package pngquant-bin:
/home/runsisi/working/src/runsisi.github.io
$ yalc check
Yalc dependencies found: [ 'cwebp-bin', 'mozjpeg', 'pngquant-bin' ]
查看 yalc 为工程添加的内容：
$ git st

注意添加 yarn 的 resolutions 处理，让依赖也使用 yalc 本地发布的版本：
$ vi package.json
...
"resolutions": {
"cwebp-bin": "file:.yalc/cwebp-bin",
"mozjpeg": "file:.yalc/mozjpeg",
"pngquant-bin": "file:.yalc/pngquant-bin"
},
...
$ yarn install
yarn install v1.22.4
[1/4] Resolving packages...
[2/4] Fetching packages...
...
需要移除 yalc 添加的 npm 包的话可以使用相应的 remove 命令：
$ yalc remove cwebp-bin mozjpeg pngquant-bin
或者手工移除相关的信息即可。
