Shapely loads geos via ctypes.
Try this in your python and see if you get anything:
在你的 python 中试试这个，看看你是否得到了什么：
from ctypes.util import find_library
find_library('geos_c')
If it doesn't work, then your geos installation is probably messed up. According to this, your geos should be in /usr/lib/libgeos_c.so.1. Is your library actually there?
如果它不起作用，那么您的 geos 安装可能搞砸了。根据这个，你GEOS应该是/usr/lib/libgeos_c.so.1。你的图书馆真的在那里吗？

Installed shapely using pip, and had the same problem. So I went ahead and installed it like so:
使用 pip 安装整齐，并有同样的问题。所以我继续安装它，如下所示：
sudo apt-get install libgeos-dev
And it worked. I'm running Ubuntu, so if you're on Fedora, you should run:
它奏效了。我正在运行 Ubuntu，所以如果你在 Fedora 上，你应该运行：
sudo yum install geos-devel

set the LD_LIBRARY_PATH, then run python
设置LD_LIBRARY_PATH，然后运行python
export LD_LIBRARY_PATH=/path_to/geos/lib:$LD_LIBRARY_PATH
python mytest.py

If you're using Anaconda like I am and ran into this, copy the libgeos* files from /usr/lib to the anaconda/lib directory and try again... :) Hopefully this saves someone else, cause I have spent hours on this.
如果您像我一样使用 Anaconda 并且遇到了这个问题，请将 libgeos* 文件从 /usr/lib 复制到 anaconda/lib 目录并重试... :) 希望这可以拯救其他人，因为我已经花了几个小时这个。

I had the same problem, and to solve it, you need to add the lib path to ld.so.conf file.
我遇到了同样的问题，要解决它，您需要将 lib 路径添加到 ld.so.conf 文件中。
To do this, Open the file:
为此，请打开文件：
sudo vi /etc/ld.so.conf
add this line
添加这一行
/usr/local/lib
And then
进而
sudo /sbin/ldconfig

In ubuntu, the following commands should take care of it. It all goes down to the following packages.
在 ubuntu 中，以下命令应该处理它。这一切都归结为以下软件包。

I had no problem on Jupyter Notebook but when I used PyCharm I encountered this issue. Tried multiple things windows on machine and the below troubleshooting steps fixed the issue
我在 Jupyter Notebook 上没有问题，但是当我使用 PyCharm 时我遇到了这个问题。在机器上尝试了多个窗口，以下故障排除步骤解决了该问题
pip install geos
Go to PyCharm, File->Settings->Project->Project Interpreter(Check you have the right path where your python.exe file is there)->Add 
转到 PyCharm，文件->设置->项目->项目解释器（检查您的 python.exe 文件所在的路径是否正确）->添加
Check that, on Virtualenv Environment -> Base Interpreter pointing to the right location where you have the python.exe
检查一下，在 Virtualenv Environment -> Base Interpreter 指向正确的位置，你有 python.exe
Same for System Interpreter->Interpreter And also Pipenv Environment -> Base Interpreter
System Interpreter->Interpreter 以及 Pipenv Environment -> Base Interpreter 相同
Make sure all are pointing to the right path. I encountered this problem as I have multiple IDE and hence multiple directories where python.exe is available.They were pointing to incorrect directories.
确保所有人都指向正确的路径。我遇到了这个问题，因为我有多个 IDE，因此有多个目录，其中 python.exe 可用。他们指向不正确的目录。
During the troubleshooting I also uninstalled and re installed conda install shapelyas I am pointing to Anaconda directory from PyCharm. Hope it helps.
在故障排除期间，我还卸载并重新安装， conda install shapely因为我从 PyCharm 指向 Anaconda 目录。希望能帮助到你。
