I recently had to use Python’s rasterio library for a project. I tried the usual pip approach:
pip install rasterio
However, I got an error similar to the following:
INFO:root:Building on Windows requires extra options to setup.py to locate needed GDAL files. More information is available in the README. ERROR: A GDAL API version must be specified. Provide a path to gdal-config using a GDAL_CONFIG environment variable or use a GDAL_VERSION environment variable.
After spending some time on Google, I found this hack that helped me circumvent this problem and hopefully it will work for you as well.
Step 1: Go to https://www.lfd.uci.edu/~gohlke/pythonlibs/
This contains a collection of Unofficial Python Binaries for Windows, by Christoph Gohlke.
Step 2: Search for GDAL and rasterio on this page
You will find several wheel files for both of these.
The number following the library name refers to the version of the library. The number following cp represents the python version. So cp34 refers to Python 3.4, and so on. Finally, at the end the Windows type is mentioned (32-bit/ 64-bit).
Thus, GDAL‑3.0.4‑cp36‑cp36m‑win_amd64.whl means GDAL version 3.0.4 for Python 3.6, for 64-bit windows.
Step 3: Download the .whl files compatible with your python version and Windows version
I am on a 64-bit Windows machine and using Python3.8. Therefore, I downloaded
Note down the path of these two files. In my case, they were stored in the Downloads folder.
Step 4: Install these two .whl files using the pip install
Open your command prompt and run the following commands
pip install <path to GDAL .whl file>
pip install <path to rasterio .whl file>
For example, in my case, to install the GDAL file, I had to run the following command:
pip install C:\Users\Yash\Downloads\GDAL-3.2.2-cp38-cp38-win_amd64.whl
Now your rasterio library should be installed. You can open python and try running
This should not give you any error now.
I hope this post helped. You can read more python related posts here: https://iotespresso.com/tag/python/.
