Docker节点:8.16.0-alpine错误:未找到:python2

我需要跑步 npm rebuild node-sass --force 在我的docker容器里

但我犯了一个错误(即使我已经安装了python)

Error: Can't find Python executable "python", you can set the PYTHON env variable.

这是我的Dockerfile

FROM node:8.16.0-alpine

RUN mkdir /app
WORKDIR /app

# --no-cache: download package index on-the-fly, no need to cleanup afterwards
# --virtual: bundle packages, remove whole bundle at once, when done
RUN apk --no-cache --virtual build-dependencies add \
    python \
    make \
    g++ \
    bash \
    && npm install \
    && apk del build-dependencies

RUN npm install -g nodemon

COPY package.json package.json
COPY client/package.json client/package.json

RUN npm install
RUN npm run install:client
RUN npm uninstall node-sass && npm install node-sass
RUN npm rebuild node-sass --force

COPY . .

LABEL maintainer="Varis Darasirikul"

VOLUME ["/app/public"]

CMD npm run dev

这是我的码头工人写的

version: '3'

services:
  web:
      build: '.'
      container_name: node-web
      # env_file:
        # - '.env'
      ports:
        - '80:8000'
        - '5000:5000'
        - '3000:3000'
      volumes:
        - '.:/app'
      networks:
        - front-tier
        - back-tier
      # depends_on:
        # - redis
        # - db

networks:
  front-tier:
  back-tier:

即使我跑的时候

docker-compose up --build --force-recreate

还是不行

如何解决这个问题?

谢谢
