"OSError:[WinError 126]找不到指定的模块".使用pvfactors库 [英] "OSError: [WinError 126] The specified module could not be found" using pvfactors library

问题描述

我开始按照网站教程但是，当尝试导入类时，出现以下错误:

However, when trying to import the classes, I got the following error:

OSError: [WinError 126] The specified module could not be found

整个错误消息:

有人可以帮助我解决此错误吗?

Can someone please help me solve this bug?

推荐答案

第二到最后一行:

anaconda3\lib\site-packages\shapely\geos.py", line 154, in _lgeos = CDLL(os.path.join(sys.prefix, 'Library', 'bin', 'geos_c.dll'))

表明您的python无法找到Shapely使用的GEOS库.Shapely是pvfactors中的依赖项.但是，看来您的anaconda环境确实安装了Shapely，因此anaconda或conda环境存在问题.解决方案几乎总是创建一个新环境并激活它.问题的一部分是pvfactors仅分布在PyPI中，并且没有conda forge或anaconda软件包，因此您必须安装 Shapely正在conda forge上

shows that your python cannot find the GEOS library that Shapely uses. Shapely is a dependency in pvfactors. However it appears your anaconda environment does have Shapely installed, so there is something wrong either with anaconda or your conda environment. The solution for this is almost always to create a new environment and activate it. Part of the problem is that pvfactors is only distributed in PyPI, and doesn't have a conda forge or anaconda package, so you have to install the requirements from Anaconda manually. Luckily Shapely is on conda forge

在anaconda提示符中尝试此操作(在 C:\ Users \ karen \> 之后输入命令):

Try this in an anaconda prompt (enter commands after C:\Users\karen\> ):

(base) C:\Users\karen\> conda create -n myenv
(base) C:\Users\karen\> activate myenv
(myenv) C:\Users\karen\> conda config --env --add channels conda-forge
(myenv) C:\Users\karen\> conda install python pvlib-python shapely matplotlib future six
(myenv) C:\Users\karen\> pip install --no-deps pvfactors
(myenv) C:\Users\karen\> conda install <other stuff like ipython Jupyter spyder etc>

祝你好运.我建议在pvfactors中创建一个问题，并要求他们添加conda forge软件包.

Good luck. I would recommend creating an issue in pvfactors and ask them to add a conda forge package.
