Docker：如何运行cython_extensions？

FROM ubuntu:14.04.2 RUN rm /bin/sh && ln -s /bin/bash /bin/sh RUN apt-get -y update && apt-get upgrade -y RUN apt-get install python build-essential python-dev python-pip python-setuptools -y RUN apt-get install libxml2-dev libxslt1-dev python-dev -y RUN apt-get install libpq-dev postgresql-common postgresql-client -y RUN apt-get install openssl openssl-blacklist openssl-blacklist-extra -y RUN apt-get install nginx -y RUN pip install "pip>=7.0" RUN pip install virtualenv uwsgi ADD canonicaliser_api /home/ubuntu/canonicaliser_api RUN virtualenv /home/ubuntu/canonicaliser_api/venv RUN source /home/ubuntu/canonicaliser_api/venv/bin/activate && pip install -r /home/ubuntu/canonicaliser_api/requirements.txt RUN export CFLAGS=-I/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/numpy/core/include/ RUN source /home/ubuntu/canonicaliser_api/venv/bin/activate && \ python /home/ubuntu/canonicaliser_api/canonicaliser/cython_extensions/setup.py \ build_ext --inplace 

最后一行崩溃：

  Traceback (most recent call last): File "/home/ubuntu/canonicaliser_api/canonicaliser/cython_extensions/setup.py", line 5, in <module> ext_modules = cythonize("*.pyx") File "/home/ubuntu/canonicaliser_api/venv/local/lib/python2.7/site-packages/Cython/Build/Dependencies.py", line 754, in cythonize aliases=aliases) File "/home/ubuntu/canonicaliser_api/venv/local/lib/python2.7/site-packages/Cython/Build/Dependencies.py", line 649, in create_extension_list for file in nonempty(extended_iglob(filepattern), "'%s' doesn't match any files" % filepattern): File "/home/ubuntu/canonicaliser_api/venv/local/lib/python2.7/site-packages/Cython/Build/Dependencies.py", line 103, in nonempty raise ValueError(error_msg) ValueError: '*.pyx' doesn't match any files ... 

请问我错过了什么？

Answer 1

我发现了这个问题。

1. 我不得不降级到Cython 0.21（这是错误的主要原因）

2. 之后我又遇到了另一个问题，因为脚本没有产生任何东西，尽pipe没有发生任何错误。 解决scheme是在执行之前在该目录中。

例如：

 RUN source /home/ubuntu/canonicaliser_api/venv/bin/activate && cd /home/ubuntu/canonicaliser_api/canonicaliser/cython_extensions/ && python setup.py build_ext --inplace 

关于Docker的痛苦部分似乎是你必须链接所有的命令，因为它似乎是无状态的。
