我正在开发一个使用 node-serialport https://github.com/voodootikigod/node-serialport的小型 nodejs (nodejs v4.3) 项目。我将它包装在 docker 图像中。首先,我成功地使用了 debian 作为基础镜像,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。然而,nodejs 项目停止使用 alpine 作为基础镜像。以下是一些日志:

安装节点串行端口日志:

> 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

├── debug@2.2.0 (ms@0.7.1)
├── nan@2.0.9
└── optimist@0.6.1 (wordwrap@0.0.3, minimist@0.0.10)

当我尝试打开串行端口时,出现错误:

正如我所说,使用 debian 作为基本映像它可以工作。我认为这可能与 alpine linux 缺少 node-serialport 所依赖的东西有关。我在https://github.com/voodootikigod/node-serialport/issues/682上创建了一个问题,但我不确定这是 node-serialport 还是 alpine linux 的问题。我读到关于 node-pre-gyp 在 alpine/busybox 上的错误。

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),因此它需要编译。

# 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。

这对我有用,在 Docker 容器中运行 Alpine Linux:

npm install serialport --unsafe-perm --build-from-source=serialport
