Node-GYP 构建 Docker 镜像时找不到 Python

Question

当我尝试构建我的 docker 镜像时，我不断收到此错误。我通过自制软件安装了Python，并且可以将它用于所有内容。VSC / PyCharm 等

但似乎node-gyp似乎无法找到可执行文件，该可执行文件位于/opt/homebrew/bin/python3

这是我的 Dockerfile

我已经尝试了回溯错误中 99.9% 的指令...但似乎无法弄清楚...任何帮助将不胜感激。

我已经使用新的 Dockerfile 和额外的一行解决了该问题

FROM node:lts-alpine

ENV NODE_ENV=production

WORKDIR /usr/src/app

COPY ["package.json", "package-lock.json*", "npm-shrinkwrap.json*", "./"]

RUN apk add --update --no-cache python3 build-base gcc && ln -sf /usr/bin/python3 /usr/bin/python

RUN npm install -g npm@8.19.1
RUN npm install --production && mv node_modules ../

COPY . .

EXPOSE 3000

RUN chown -R node /usr/src/app

USER node

CMD ["node", "./src/index.js"]

有了这条线。

RUN apk add --update --no-cache python3 build-base gcc && ln -sf /usr/bin/python3 /usr/bin/python

这解决了这个问题。
