遇到报错，如下

从报错信息来看是nasm缺失，怎么解决呢？还得去 issue 看，去这里 (opens new window)。

安装相应的包，就可以正常安装了。
```
# for macOS
brew install automake nasm zlib

# for Ubuntu
sudo apt-get install nasm zlib1g-dev
```

当然也有人这样安装也是可以的，不过我已经解决上述问题了，就没尝试，这里也贴出来，见issue (opens new window)。
```
brew install automake autoconf libtool
```

后话：

安装 png 插件时遇到类似的问题

yarn add imagemin-pngquant

报错如下

解决方式也类似，安装就好了。

brew install libpng

在 windows 上安装，又出幺蛾子了，所幸有前辈趟坑了，见issue (opens new window)。安装 VC runtime 后确实管用。

如果还是有问题，试试降低版本：

npm install imagemin-pngquant@5.0.1 --save
npm install pngquant-bin@4.0.0 --save
