[英]Shapely OSError: Could not find lib c or load any of its variants []
I'm just trying to use the demo code.我只是想使用演示代码。 I run the following in Jupyter Notebook:我在 Jupyter Notebook 中运行以下命令:
from shapely.geometry import shape
Which gives me the following:这给了我以下内容:
OSError Traceback (most recent call last)

OSError: Could not find lib c or load any of its variants [].
However, if I run from the interpreter, everything is fine.但是,如果我从解释器运行,一切都很好。
Any idea what's going on?知道发生了什么吗?
I simply uninstalled Shapely and re-installed it to fix the issue.我只是卸载了 Shapely 并重新安装它来解决这个问题。
python -m pip uninstall shapely
python -m pip install shapely
The way I fixed it:我修复它的方式:
apk add geos libc-dev musl-dev
pip install Shapely
For me, only works after installing Shapely from the shapely lib and executing the following command from Anaconda Prompt:对我来说,只有在从shapely lib安装 Shapely 并从 Anaconda Prompt 执行以下命令后才有效:
pip install Shapely-1.7.1-cp37-cp37m-win_amd64.whl --force-reinstall
This forces a re-install of shapely.这迫使重新安装匀称的。
@user2977865 and @anothernode are correct in their approach but it may not work for everyone. @user2977865 和 @anothernode 的方法是正确的,但它可能不适用于所有人。 By default, shapely
will look for libraries in the DYLD_PATH
.默认情况下, shapely
将在DYLD_PATH
查找库。
I had it set to DYLD_LIBRARY_PATH=/usr/local/lib/:/usr/local/mysql/lib/
我将它设置为DYLD_LIBRARY_PATH=/usr/local/lib/:/usr/local/mysql/lib/
But these libraries are placed in /usr/lib
.但是这些库被放置在/usr/lib
。
So I had to modify it as follows:所以我不得不修改它如下:
export DYLD_LIBRARY_PATH=/usr/lib/:/usr/local/mysql/lib/
Bonus note: Ensure that your environment variables have been set by restarting terminal and clearing cache of any IDEs you might be using.额外说明:通过重新启动终端并清除您可能正在使用的任何 IDE 的缓存,确保已设置您的环境变量。
I had a very similar issue running code in aws lambda with the error message:我在 aws lambda 中运行代码时遇到了一个非常相似的问题,并显示错误消息:
OSError: Could not find lib c or load any of its variants ['libc.musl-x86_64.so.1'].
I added musl-dev
to my container installation and adapted the symlink:我将musl-dev
添加到我的容器安装中并调整了符号链接:
ln -s /usr/lib/x86_64-linux-musl/libc.so /lib/libc.musl-x86_64.so.1
我不得不做一个conda update --all
来解决这个问题。
试试这个可能对你有帮助:
pip install --upgrade --force-reinstall shapely
For macOS users:对于 macOS 用户:
brew install geos
pip3 install shapely --upgrade
