node.js - 无法在节点上构建 node-re2：12.18.1-alpine docker 映像

问题描述

我尝试在最新的节点 12.18.1 lts alpine 上构建 node-re2，以便以后可以将二进制文件复制到生产映像中。不幸的是，它无法编译。我错过了什么？即使 ld-linux-x86-64.so.2 文件应该在包中，安装 libc6-compat 或 gcompatRUN apk add --no-cache gcompat也无济于事。RUN apk add --no-cache libc6-compat

我的 dockerfile 是

FROM node:12.18.1-alpine as re2-builder

WORKDIR /opt

RUN apk add python make g++ \
    && npm install re2@1.15.0

构建时我得到这个：

Writing to build/Release/re2.node ...

> re2@1.15.0 verify-build /opt/node_modules/re2
> node scripts/verify-build.js

internal/modules/cjs/loader.js:1188
  return process.dlopen(module, path.toNamespacedPath(filename));
                 ^

解决方案

Alpine 使用musl libc，它的共享库加载器名称ld-musl-x86_64.so.1位于/lib目录中。ld-linux-x86-64.so.2是在 Ubuntu 或其他标准发行版中使用的 glibc 共享库加载器。有兼容层包名称libc6-compat尝试添加。

apk add libc6-compat

或尝试符号链接原始文件

ln -s /lib/ld-musl-x86_64.so.1 /lib/ld-linux-x86-64.so.2

那应该解决。

Error loading shared library ld-linux-x86-64.so.2: No such file or directory
