ModuleNotFoundError:没有名为“versioneer"的模块

问题描述

我正在使用下面的 dockerfile 来构建图像.

I am using the below dockerfile to build an image .

FROM <custom registry>/python:alpine3.7
# Copy local code to the container image.
ENV APP_HOME app
WORKDIR $APP_HOME
COPY . .
#RUN pip install versioneer
RUN pip install Flask google-auth google-cloud-storage numpy datetime pandas sklearn
ENV PORT 8080
CMD ["python", "app_hello.py"]

当我尝试进行 docker build 时，它给了我以下错误

When I tried to do a docker build it gave me the below error

File "setup.py", line 37, in <module>
      import versioneer
  ModuleNotFoundError: No module named 'versioneer'
  
  ----------------------------------------
Command "/usr/local/bin/python /usr/local/lib/python3.7/site-packages/pip/_vendor/pep517/_in_process.py get_requires_for_build_wheel /tmp/tmp8gvrvde_" failed with error code 1 in /tmp/pip-install-s551_g8p/numpy

我也尝试安装 versioneer，但没有成功.我在这里错过了什么?

I tried to install versioneer as well , but it did not work. What am I missing here ?

推荐答案

命令/usr/local/bin/python/usr/local/lib/python3.7/site-packages/pip/_vendor/pep517/in_process.py get_requires_for_build_wheel/tmp/tmp8gvrvde"失败，错误代码 1 在/tmp/pip-install-s551_g8p/numpy

Command "/usr/local/bin/python /usr/local/lib/python3.7/site-packages/pip/_vendor/pep517/in_process.py get_requires_for_build_wheel /tmp/tmp8gvrvde" failed with error code 1 in /tmp/pip-install-s551_g8p/numpy

构建numpy时出现该错误，这表明您需要升级pip才能使其工作:

The error happens when build numpy, and this indicates you need to upgrade pip to make it work:

pip install --upgrade pip

另外，您需要安装编译器以使用 next 进行构建:

Additional, you need install compiler for build with next:

apk add build-base

有了上面的例子，接下来是一个可行的 Dockerfile 示例:

With above, a sample workable Dockerfile as next:

FROM python:alpine3.7
RUN pip install --upgrade pip; apk add build-base; pip install numpy
RUN python -c "import numpy; print(numpy.__version__)"

输出:

$ docker build -t abc:1 .
