无法导入 Shapely(Ubuntu、Python) [英] Cannot import Shapely (Ubuntu, Python)

问题描述

我下载了 Shapely 来做一些多边形工作(在 Ubuntu AWS 实例上).一切都安装得很好，我使用了 wget.当我第一次遇到我要解释的错误时，我也做了 pip，但它只是说一切都在那里，所以我认为下载不是问题.

I downloaded Shapely to do some polygon work (on a Ubuntu AWS instance). Everything installed just fine, I used wget. I also did pip when I first encountered the error I'm about to explain, but it just said everything was there, so I don't think the download is the issue.

无论如何，当我尝试导入任何from匀称的东西时，我得到这个错误:

Anyway, when I try to import anything from shapely, I get this error:

OSError: libgeos_c.so: cannot open shared object file: No such file or directory

当我只是说导入匀称"时，一切都很好.但是，当我需要从库的更深处导入任何内容时，它会崩溃.我首先用 from shapely.geometry import polygon 尝试了它，但对于包内的任何东西都是一样的.有没有人之前遇到过这个问题/知道解决方案?

When I just say "import shapely", it all goes fine. However, when I need to import anything from deeper in the library, it crashes. I first tried it with from shapely.geometry import polygon but it's the same for anything from within the package. Has anyone had this problem before/know the solution?

推荐答案

在 Ubuntu 上，显然你总是应该使用 sudo apt-get install 来获取库等.当我执行 wget 或 pip install 时，我只是将文件粘贴在一个随机位置，而不是我的实际路径中.

On Ubuntu, apparently you're always supposed to use sudo apt-get install to get libraries and such. When I did wget or pip install, I was just sticking the files in a random spot, not in my actual path.

所以，我想总是使用 sudo apt-get install...

So, I guess always use sudo apt-get install...
