Installing extension modules can be an issue with pip. This is why conda exists. conda is an open-source BSD-licensed cross-platform package manager. It can easily install NumPy.
安装扩展模块可能是 pip 的问题。这就是 conda 存在的原因。conda 是一个开源的 BSD 许可的跨平台包管理器。它可以轻松安装 NumPy。
Two options:
两种选择：
- Install Anaconda (http://www.continuum.io/downloads)
- Install Miniconda (http://repo.continuum.io/miniconda/index.html) and then go to a command-line and type
conda install numpy(make sure your PATH includes the location conda was installed to).
- 安装 Anaconda ( http://www.continuum.io/downloads)
- 安装 Miniconda ( http://repo.continuum.io/miniconda/index.html)，然后转到命令行并键入
conda install numpy（确保您的 PATH 包含安装 conda的位置）。

Make sure you have python-dev installed (as you'll definitely see this same error if you don't).
确保你已经安装了 python-dev（如果你不安装，你肯定会看到同样的错误）。
dpkg -l python-dev

Some File can not be installed with pip and need to be installed from your platform's packages.
有些文件不能用 pip 安装，需要从你平台的包中安装。

I downloaded python 37, and I customized install location. Then I tried to install numpy using pip: failed error code 1. Then I deleted python 37, downloaded python 36 without customizing install location. Then I installed numpy using pip: successful. Perhaps customizing install location caused the error.
我下载了 python 37，并自定义了安装位置。然后我尝试使用 pip: failed error code 1 安装 numpy。然后我删除了 python 37，下载了 python 36 而不自定义安装位置。然后我使用 pip: 成功安装了 numpy。也许自定义安装位置导致了错误。
