【问题描述】：
我正在 Docker 中运行这个 Jenkins Image。
在我的一个构建中，我正在尝试安装以下软件包：
json
"devDependencies": {
"@babel/core": "^7.0.0-beta.40",
"@babel/preset-env": "^7.0.0-beta.40",
"babel-loader": "^8.0.0-beta.0",
"css-loader": "^0.28.11",
"file-loader": "^1.1.11",
"html-webpack-plugin": "^3.1.0",
"image-webpack-loader": "^4.2.0",
"node-sass": "^4.8.3",
"sass-loader": "^6.0.7",
"style-loader": "^0.20.3",
"webpack": "^4.0.1",
"webpack-cli": "^2.0.13",
"webpack-dev-server": "^3.1.1"
}
但是，尝试安装 pngquant-bin@4.0.0 时，构建一直失败：

> node scripts/install.js

我已经更新了 Docker 镜像，尝试了不同版本的 Node（7.9.0、8.11.1）并一直遇到同样的错误。
不知道如何解决让pngquant-bin 处理此版本的问题。
任何帮助将不胜感激。
