在docker中的python中安装pandas失败

Question

我已经尝试让 docker 文件运行三天了，但始终无法安装 pandas。

在这里你可以看到我的 Dockerfile：

# pull official base image
FROM python:3.6.5-alpine

# set work directory
WORKDIR /usr/src/app

# set environment variables
ENV PYTHONDONTWRITEBYTECODE 1
ENV PYTHONUNBUFFERED 1

RUN apk update
RUN apk add postgresql-dev cargo gcc python3-dev libffi-dev musl-dev zlib-dev jpeg-dev #--(5.2)

COPY . /usr/src/app/
# install dependencies
RUN pip install --upgrade pip
RUN pip install -r requirements.txt

我的requirement.txt是：

wheel==0.36.2
asgiref==3.2.10
backcall==0.2.0
beautifulsoup4==4.9.1
certifi==2020.6.20

我正在尝试 python 3.6.5、3.7、3.8、3.8.5，但无法安装 pandas 要求已满足，但轮子显示：

gcc -Wno-unused-result -Wsign-compare -DNDEBUG -g -fwrapv -O3 -Wall -DTHREAD_STACK_SIZE=0x100000 -fPIC -DNPY_NO_DEPRECATED_API=0 -Ipandas/_libs/window -I./pandas/_libs -I/tmp/pip-build-env-e3sdep4m/overlay/lib/python3.7/site-packages/numpy/core/include -I/usr/local/include/python3.7m -c pandas/_libs/window/aggregations.cpp -o build/temp.linux-x86_64-3.7/pandas/_libs/window/aggregations.o

  gcc: fatal error: cannot execute 'cc1plus': execvp: No such file or directory
command gcc failed with exit status 1
"failed building wheel for pandas 
pep517 err

所以我用：

# pull official base image
FROM python:3.6.5-alpine

# set work directory
WORKDIR /usr/src/app

# set environment variables
ENV PYTHONDONTWRITEBYTECODE 1
ENV PYTHONUNBUFFERED 1

RUN apk update
RUN apk add postgresql-dev cargo gcc python3-dev libffi-dev musl-dev zlib-dev jpeg-dev #--(5.2)

COPY . /usr/src/app/
# install dependencies
RUN pip install --upgrade pip
RUN pip install -r requirements.txt

但它不起作用，显示相同的错误。

如何在Python中安装pandas？

你需要g++经历这个。

尝试更新 Dockerfile 中的安装命令：

RUN apk add g++ postgresql-dev cargo gcc python3-dev libffi-dev musl-dev zlib-dev jpeg-dev
