我试图建立一个码头形象使用Visual Studio代码以下本教程“https://code.visualstudio.com/docs/python/tutorial-deploy-containers“。
我使用pyodbc包创建了一个django应用程序,它连接到Azure上的MSSQLserver。
在构建Docker映像期间,我收到以下错误消息:
unable to execute 'gcc': No such file or directory
error: command 'gcc' failed with exit status 1
----------------------------------------
Failed building wheel for pyodbc
以及
unable to execute 'gcc': No such file or directory
error: command 'gcc' failed with exit status 1
----------------------------------------
Failed building wheel for typed-ast
我读过linux系统的解决方案,其中应该安装python-dev,但由于我在windows机器上工作,这不是解决方案。
然后我读到在windows上所有需要的文件都在python安装的“include”目录中,但是在venv安装中这个目录是空的...所以我创建了一个到原始“include”的目录连接,错误仍然存在。
我的docker文件包含在下面。
# Python support can be specified down to the minor or micro version
# (e.g. 3.6 or 3.6.3).
# OS Support also exists for jessie & stretch (slim and full).
# See https://hub.docker.com/r/library/python/ for all supported Python

# Tell nginx where static files live (as typically collected using Django's
# collectstatic command.
ENV STATIC_URL /app/static_collected
# Copy the app files to a folder and run it from there
WORKDIR /app
ADD . /app
# Make app folder writable for the sake of db.sqlite3, and make that file also writable.
# RUN chmod g+w /app
# RUN chmod g+w /app/db.sqlite3
# If you prefer miniconda:
#FROM continuumio/miniconda3
LABEL Name=hello_django Version=0.0.1
EXPOSE 8000
# Using pip:
RUN python3 -m pip install -r requirements.txt
CMD ["python3", "-m", "hello_django"]
# Using pipenv:
#RUN python3 -m pip install pipenv
#RUN pipenv install --ignore-pipfile
#CMD ["pipenv", "run", "python3", "-m", "hello_django"]
# Using miniconda (make sure to replace 'myenv' w/ your environment name):
#RUN conda env create -f environment.yml
#CMD /bin/bash -c "source activate myenv && python3 -m hello_django"
我可以在没有错误的情况下使用一些帮助来构建图像。
基于2 ps的答案,我几乎在docker文件的顶部添加了这些行
FROM tiangolo/uwsgi-nginx:python3.6-alpine3.7
RUN apk update \
&& apk add apk add gcc libc-dev g++ \
&& apk add libffi-dev libxml2 libffi-dev \
&& apk add unixodbc-dev mariadb-dev python3-dev
并收到一个新错误...

发现添加
RUN echo "ipv6" >> /etc/modules
帮助解决上述错误。摘自:https://github.com/gliderlabs/docker-alpine/issues/55
应用程序现在可以工作了,除了预期的到MsSQL数据库的连接仍然不起作用。
Error at /
('01000', "[01000] [unixODBC][Driver Manager]Can't open lib 'ODBC Driver 13 for SQL Server' : file not found (0) (SQLDriverConnect)")
我想我应该去弄些 Docker 的文件。

我放弃了alpine的解决方案,转而使用debian
flvtvl502#
你需要使用
apk
来安装gcc
和其他需要构建pip
依赖项的本机依赖项,对于你列出的那些(typedast和pyodbc),我认为它们应该是:doinxwow3#
只是想把这个留给将来的任何人。我试图启动一个带有Spacy模型的Python-Flask应用程序到Docker容器中,但是使用pip安装包时遇到了问题。从这篇文章中可以看出,gcc没有正确安装,所以一些基本的依赖项失败了。
解决了我的问题:
还有其他几个失败的软件包谢谢!
