命令“ python setup.py egg_info”在/ tmp / pip-install-jsegcbha / mysqlclient /中失败，错误代码为1

Question

MacOS High Sierra

Python 3.6.3

docker-compose.yml

version: '3'
services:
  celery:
    container_name: "cache_bot"
    build:
      context: .
      dockerfile: docker/celery/Dockerfile
    command: "celery -A cache_bot.app worker --loglevel=info"
    volumes:
      - ./src:/www

Dockerfile

FROM python:3.6-alpine

RUN apk --update add --no-cache bash gcc libc-dev unixodbc-dev python3-dev

ADD ./src /www
ADD ./requirements.txt /home

WORKDIR /www

RUN pip install -r /home/requirements.txt

requirements.txt

mysqlclient==1.3.12
...

When I run command 'docker-compose build' I get the error:

Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-install-jsegcbha/mysqlclient/

ERROR: Service 'celery' failed to build: The command '/bin/sh -c pip install -r /home/requirements.txt' returned a non-zero code: 1

Full traceback:

Collecting mysqlclient==1.3.12 (from -r /home/requirements.txt (line 8))

Complete output from command python setup.py egg_info:

/bin/sh: mysql_config: not found

Traceback (most recent call last):

File "/tmp/pip-install-jsegcbha/mysqlclient/setup.py", line 17, in metadata, options = get_config()

File "/tmp/pip-install-jsegcbha/mysqlclient/setup_posix.py", line 44, in get_config libs = mysql_config("libs_r")

File "/tmp/pip-install-jsegcbha/mysqlclient/setup_posix.py", line 26, in mysql_config

raise EnvironmentError("%s not found" % (mysql_config.path,))

OSError: mysql_config not found

Actually, mysql_config is by path /usr/local/bin and this path is set up in $PATH

I've tried - RUN pip install --upgrade setuptools - in my Dockerfile. It did not help.

ENV PATH /usr/local/bin:$PATH in Dockerfile did not help as well.

Thanks a lot!!!!!!!!!!!!!

Answer 1

I had the same issue try this on the command line

brew install mysql-connector-c
brew install mysql
brew unlink mysql-connector-c
sudo pip install pymysql
sudo pip install mysqlclient

Answer 2

The problem is in your Dockerfile the python:3.6-alpine is a reduced version of Python and the mysqlclient is looking for a development headers and libraries.

It is the official page Pypi: mysqlclient

Prerequisites: You may need to install the Python and MySQL development headers and libraries...

My solution:

In my case I had the slim version and I changed to a Python 3 (3.7) and it works.

#FROM python:3-slim
FROM python:3
