yarn 安装进行时，显现错误 node_modules\gifsicle: Command failed.

错误详情如下

解决办法：

1. 在 package.json 文件中 配置忽略该错误

  "resolutions": {
    "//": "Used to install imagemin dependencies, because imagemin may not be installed in China. If it is abroad, you can delete it",
    "bin-wrapper": "npm:bin-wrapper-china",
    "rollup": "^2.72.0"
  }

2. yarn设置代理

yarn config list

// ID & Passなし
yarn config set proxy http://example.com:port -g

// ID & Passあり
yarn config set proxy http://username:password@host:port -g

// ID & Passなし
yarn config set https-proxy http://example.com:port -g

// ID & Passあり
yarn config set https-proxy http://username:password@host:port -g

// 设置proxy
yarn config set https-proxy http://127.0.0.1:7890
yarn config set proxy http://127.0.0.1:7890

// 查看proxy
yarn config get https-proxy 
yarn config get proxy 

配置代理没成功！！！
