Double requirement given when trying to use pip install pandas
提问by Stijn
I want to build a Docker container using a Dockerfile containing pip install -r requirements.txt. pandas==0.22.0 is included in this requirements.txt file. Untill two days ago, the Docker container was perfectly build. Starting from yesterday, I receive an error:
我想使用包含pip install -r requirements.txt. pandas==0.22.0 包含在这个 requirements.txt 文件中。直到两天前，Docker容器才完美构建。从昨天开始，我收到一个错误：

双重要求给出：从numpy的== 1.12.1 https://pypi.python.org/packages/02/64/c6c1c24ff4dbcd789fcfdb782e343ac23c074f6b8b03e818ff60eb0f937f/numpy-1.12.1-cp34-cp34m-manylinux1_x86_64.whl#md5=6288d4e9cfea859e03dc82879539d029（已经在numpy的== 1.9.3从 https://pypi.python.org/packages/fc/1b/a1717502572587c724858862fd9b98a66105f3a3443225bda9a1bd16ee14/numpy-1.9.3-cp34-cp34m-manylinux1_x86_64.whl#md5=e1130c8f540a759d79ba5e8960f6915a，名称= 'numpy的'）
This error occurs both on Mac (Docker version: 18.03.0-ce-mac58 (23607)) and Ubuntu 16.04.3 (Docker version: 17.12.0-ce, build c97c6d6).
此错误在 Mac（Docker 版本：18.03.0-ce-mac58 (23607)）和 Ubuntu 16.04.3（Docker 版本：17.12.0-ce，构建 c97c6d6）上都会发生。
I already tried to use different versions op pandas, to preinstall numpy, to remove pands from the requirements.txt file and install it seperately. As well as trying to install with apt-get install python-pandas. For the latter solution pandas v14 was installed, while I need at least v19.
我已经尝试使用不同版本的 op pandas，预安装 numpy，从 requirements.txt 文件中删除 pands 并单独安装。以及尝试使用apt-get install python-pandas. 对于后一种解决方案，安装了pandas v14，而我至少需要v19。
