python - 安装 OR-tools 时没有版本属性

Question

我正在尝试在 Linux for Python 上安装 OR-tools，这是 Google 的一个优化库。
https://developers.google.com/optimization/introduction/installing.html#unix_binary

我正在使用新下载的虚拟机(操作系统盒中的 Ubuntu 16.10 Yakkety Yak)，所以我怀疑我的系统是否存在问题(除非我还没有安装我需要的东西)。

我也怀疑 OR-tools 是问题所在。除了:

sudo apt-get install python-setuptools
sudo apt-get install g++
下载的 Python—tar.gz，在 Downloads 中提取
进入下载后运行“make install”

我收到错误消息“您正在使用没有版本属性的 ortools 模块”。有谁知道这可能意味着什么？

我已经尝试了命令提示符建议的两个技巧:

运行/usr/bin/python setup.py install --user 工作，但错误“警告:install_lib:'build/lib.linux-x86_64-2.7'不存在 - 没有要安装的 Python 模块”弹出。

删除 init.pyc 文件告诉我删除 init.py 文件，然后它说 or-tools 没有找到。

非常感谢任何帮助，仍在学习 Linux，所以我确定我在做一些愚蠢的事情......

见troubleshooting page of the Google or-tools project ，详细说明此错误:

This occurs when you try to install a binary distribution, but the installer is unable to build the ortools package for your operating system. In this case, you can still install and run OR-Tools from source files, and even build the python package yourself. You can do so, by following these steps:

• Install and compile OR-Tools as described in Linux/Mac OS X source installation or Windows source installation.
• Don't forget to make sure that everything is working fine by running make test.
• Run make pypi_archive. You will find the package under a directory called temp.

就我个人而言，从我的 Ubuntu 16.04 VM 上的源文件构建也不起作用(可能是由于虚拟化引起的一些错误)。

但是，我发现 this Python .egg file on PyPi用于 Ubuntu 16.04 上的 or-tools，使用 easy_install <filename>.egg 安装相当容易(确保首先使用 pip install setuptools 下载 Python setuptools)。

他们有these easy to install versions available for other versions of Ubuntu比你的，比如 16.04 和 17.04。如果您即将升级，您可能想尝试其中之一。否则，您可以尝试easy_install一个与操作系统无关的版本 .egg 文件。
