node.js – 在alpine linux上失败的node-serialport

我正在使用node-serialport https://github.com/voodootikigod/node-serialport的一个小nodejs(nodejs v4.3)项目.我将它包装在一个docker镜像中.首先,我成功使用debian作为基本图像,但它的总大小约为600MB.然后我切换到alpine linux https://hub.docker.com/_/alpine/并实现了100MB的图像大小.但是,nodejs项目停止使用alpine作为基本图像.这是一些日志：

安装node-serialport日志：

> serialport@2.0.6 install /app/node_modules/serialport
> node-pre-gyp install --fallback-to-build

[serialport] Success: "/app/node_modules/serialport/build/Release/node-v46-linux-x64/serialport.node" is installed via remote

└── optimist@0.6.1 (wordwrap@0.0.3,minimist@0.0.10)

当我尝试打开串口时出现错误：

正如我所说,以debian为基本图像,它起作用.我认为这可能与alpine linux缺少node-serialport所依赖的事实有关.我在https://github.com/voodootikigod/node-serialport/issues/682创建了一个问题,但我不确定这是node-serialport还是alpine linux的问题.我读到了关于node-pre-gyp在alpine / busyBox上出错的问题.


最佳答案
https://github.com/voodootikigod/node-serialport/pull/710
Alpine是一个(非常)小的发行版,但它使用musl标准库而不是glibc(大多数其他Linux发行版使用),所以它需要编译.

# If you don't have node/npm already,add that first
sudo apk add --no-cache nodejs

# Add the necessary build and runtime dependencies
sudo apk add --no-cache make gcc g++ python linux-headers udev

# Then we can install serialport,forcing it to compile
npm install serialport --build-from-source=serialport

我测试了它.它解决了这个问题.
