如何在 Windows 10 中为 python 安装 gdal？

Question

I'm trying to install gdal library. i've tried the things recomended here Installing gdal python library on windows using conda (DLL load failed)

and here: https://github.com/felipunky/GISPython/blob/master/README.md

then i tried:

C:\Users\User>pip install D:\Seba\Programas\GDAL-3.3.0-cp37-cp37m-win_amd64.whl
Requirement already satisfied: GDAL==3.3.0 from file:///D:/Seba/Programas/GDAL-3.3.0-cp37-cp37m-win_amd64.whl in c:\users\user\appdata\local\programs\python\python37\lib\site-packages (3.3.0)
WARNING: You are using pip version 20.1.1; however, version 21.1.2 is available.
You should consider upgrading via the 'c:\users\user\appdata\local\programs\python\python37\python.exe -m pip install --upgrade pip' command.

During handling of the above exception, another exception occurred:

    return _bootstrap._gcd_import(name[level:], package, level)

any recomendation?

试试这个： sudo easy_install GDAL

Answer 2

conda install of gdal in windows does work.

You haven't given much to go on, but my guess is that you have not activated the conda environment into which gdal has been installed.

Normally your command prompt would look like this, if you had activated it

(gdal_env_name) C:\Users\User>python

Also, run

conda list

to check that all the expected libraries are there.
