Question

我正在尝试运行在python中创建的程序，我收到错误：

“ImportError：无模块名称多边形”

我使用的是ubuntu，python 2.7和EPD 7.3-1。

如何下载python的模块Polygon的包和C扩展名？

我试过了：

sudo apt-get install python-polygon
sudo apt-get install python-polygon2

没有任何事情发生。

我从autor的页面下载了zip文件：“Polygon2-2.0.6.rar”。之后，我将Polygon2-2.0.6.rar提取到Polygon2-2.0.6，然后我去那个文件夹并运行python setup.py install

给我：

jose@jose-Satellite-L845:~/Descargas/Polygon2-2.0.6$ python setup.py install

Using NumPy extension!

请帮忙。提前谢谢。

Answer 1

下载zip文件，解压缩文件，cd进入该文件夹，运行python setup.py build和python setup.py install。

编辑：根据你的回答，你需要安装python-dev。

命令是：sudo apt-get install python-dev
