Node.JS：由于 node-sass 和 node-gyp，尝试使用 docker-compose up 退出运行 docker 项目答案

【问题标题】：Node.JS: Trying to run docker project with docker-compose up exits due to node-sass and node-gypNode.JS：由于 node-sass 和 node-gyp，尝试使用 docker-compose up 退出运行 docker 项目
【发布时间】：2021-12-30 23:27:01
【问题描述】：

我正在尝试从 MacBook Air M1 运行我的一个 Docker 工作项目，但在执行 docker-compose up 时出现以下错误。显然 它找不到 python 安装，即使我可以从终端同时执行 python --version 和 python3 --version。我对 Docker 比较陌生，但我尝试对所有可能的事情进行故障排除以解决此错误

我尝试了错误提示的所有事情 - 设置 python 的路径变量，并尝试将 NPM 的配置设置为 python 的路径但没有运气......

我也尝试将 node 降级到 v16，因为 node-sass 6.0.1 与 node v17 according to the docs 不兼容

我通过自制软件安装了 python 3.9.8，运行 which python3 输出 /opt/homebrew/bin/python3

node -v：v16.13.0

npm -v：v8.1.0

echo $PATH:/Library/Frameworks/Python.framework/Versions/3.10/bin /opt/homebrew/bin:/opt/homebrew/sbin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Library/Apple/usr/bin

npm config list:


prefix = "/opt/homebrew" 

; "global" config from /opt/homebrew/etc/npmrc

; python = "/opt/homebrew/opt/python@3.9/libexec/bin" ; overridden by user

; "user" config from /Users/**username**/.npmrc

python = "/opt/homebrew/opt/python@3.9/libexec/bin"

【问题讨论】：

您已经在您的计算机中安装了 python，但它不存在于运行 npm 的 docker 容器中……您需要在同一容器内的 npm 安装过程之前将 python 安装在容器中。 ..
或者我不确定是否有任何方法可以使用 python 的容器并将其在 docker compose 中链接到另一个容器.. 但总的来说.. python 安装在你的 Mac 上但没有在 docker 环境中，所以你需要解决这个问题。

标签： python node.js npm docker-compose node-sass

【解决方案1】：

问题：

python 本地安装在你的 macbook 上，但不在 docker 容器内（这是一个独立的虚拟操作系统）。

解决方案

您需要在运行 nodejs 脚本或 npm 命令的同一容器中安装 python。

在 dockerFile 中拉取你的 nodejs 图像后尝试添加这个

RUN apt-get update || : && apt-get install python -y

这适用于基于 debian 或基于 debian 的 linux 发行版 ...（如果您有基于 debian 的官方 Node 映像，那么在拉取映像运行后上一行应该可以正常工作，您需要在同一个容器中安装 python )。

【讨论】：

就我而言，在 dockerFile 中的 yarn 之前添加 RUN apk add --update python3 make g++\ && rm -rf /var/cache/apk/* 解决了这个问题。仍然好奇相同的容器如何在没有这个的其他机器上正常工作......
@Stepan 您使用的是 alphine 版本......如果没有安装 python，任何地方都会出现同样的问题......因为 node-sass 需要 node-gyp 进行本机编译和 node-gyp需要 python 来解释.. :) toturial 的人可能错过了它，或者他可能没有使用 node-sass 或任何本机模块。
