ModuleNotFoundError:没有名为“Versioner”的模块

Question

我正在使用下面的dockerfile构建一个图像

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构建时，它给了我以下错误

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Versioner，但没有成功。 我错过了什么

Answer 1

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

生成numpy时会发生错误，这表示您需要升级pip以使其正常工作：

pip install  upgrade pip

此外，您还需要安装编译器，以便使用下一步进行生成：

apk add build-base

在上面的示例中，下面是一个可用的Dockerfile：

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 .
