Question

我正在为数据科学项目构建operator<图像。

我通过node安装核心依赖项。

Dockerfile-dev

docker

一切都累积到RUN apk add <package>，此时出现此错误：

FROM python:3.6-alpine

# add and install requirements
COPY ./requirements.txt /usr/src/app/requirements.txt
RUN pip install -r requirements.txt

但是pandas已预先安装：

运行numpy的setup.py安装：状态为“完成”

尚未击败，我将Complete output from command python setup.py egg_info: Traceback (most recent call last): File "/usr/local/lib/python3.6/site-packages/pkg_resources/__init__.py", line 359, in get_provider module = sys.modules[moduleOrReq] KeyError: 'numpy' During handling of the above exception, another exception occurred: Traceback (most recent call last): File "<string>", line 1, in <module> File "/tmp/pip-install-v7gyw8y_/pandas/setup.py", line 732, in <module> ext_modules=maybe_cythonize(extensions, compiler_directives=directives), File "/tmp/pip-install-v7gyw8y_/pandas/setup.py", line 475, in maybe_cythonize numpy_incl = pkg_resources.resource_filename('numpy', 'core/include') File "/usr/local/lib/python3.6/site-packages/pkg_resources/__init__.py", line 1144, in resource_filename return get_provider(package_or_requirement).get_resource_filename( File "/usr/local/lib/python3.6/site-packages/pkg_resources/__init__.py", line 361, in get_provider __import__(moduleOrReq) ModuleNotFoundError: No module named 'numpy' ---------------------------------------- Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-install-v7gyw8y_/pandas/（此版本在我的conda numpy环境中使用）移至pandas==0.20.3，并安装了它，日志显示：

py36

但是，在构建时间之后，运行容器会记录以下错误：

requirements.txt

所以它是由Successfully built: pandas Installing collected packages: pandas Successfully installed: pandas-0.20.3安装的，但是找不到吗？

如何通过users_1 | File "/usr/src/app/project/api/classifiers/metadata/learn.py", line 14, in <module> users_1 | import pandas as pd users_1 | ModuleNotFoundError: No module named 'pandas'安装pip，以保持我的数据科学项目的构建一致性？

Answer 1

在Dockerfile-dev中添加以下行对我有用：

&& pip install --no-cache-dir $PYTHON_PACKAGES \
&& pip3 install 'pandas<0.21.0' \ # <-------------------- new line
&& apk del build-runtime \
&& apk add --no-cache --virtual build-dependencies $PACKAGES \

我必须明确指定pandas版本。
