node-serialport 在高山 linux 上失败

Question

我正在开发一个小型 nodejs (nodejs v4.3) 项目，该项目使用 node-serialport https://github.com/voodootikigod/node-serialport. I wrapped it in a docker image. First I successfully used debian as a base image but it had a total size of about 600MB. Then I switched to 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 作为基础图像。以下是一些日志：

安装节点串口日志：

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

└── 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，以 debian 作为基础映像它工作正常。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，但我不确定这是节点串口问题还是 alpine linux 问题。我在 alpine/busybox 上了解到 node-pre-gyp 有问题。

Answer 1

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），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

我测试过了。它解决了这个问题。

Answer 2

这对我有用，运行 Alpine Linux 在 Docker 容器中：

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