docker - Jenkins构建无法安装pngquant

Question

我正在Docker中运行此Jenkins Image。

在我的其中一个版本中，我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，在尝试安装pngquant-bin@4.0.0时，构建始终失败:

> node-sass@4.8.3 install /var/jenkins_home/workspace/crypto-coaster/node_modules/node-sass
> 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)，并继续遇到相同的错误。

不知道如何解决使 pngquant-bin在此版本上工作。

任何帮助将不胜感激。

根据此问题https://github.com/imagemin/pngquant-bin/issues/78。
我使用此dockerfile创建一个新镜像，并且工作正常。

FROM jenkins/jenkins:lts
USER root
RUN apt-get update && apt-get install -y gcc make libpng-dev
USER jenkins
