I solved this problem by installing this:

or
python3 -m pip install --upgrade pip setuptools wheel

It seems to be related to a GeoPandas dependency: Fiona. This package has a GDAL API. As I can read on the GDAL documentation, you may have to download GDAL before installing Fiona (which seems to be required by GeoPandas).

Thaks!!I have to download some wheels with 3.8 version, even my version is 3.10; like:
Fiona
GDAL
Pyproject
Shapely
then install wiw pip.. done.

Someone can help me - It is important for the next work and I can't solve it.
Thanks.

I suggest to use PyCryptodome instead of PyCrypto.
https://pycryptodome.readthedocs.io/en/latest/src/vs_pycrypto.html
Here's what PyCryptodome said:
PyCryptodome exposes almost the same API as the old PyCrypto so that most applications will run unmodified.
And it is much more easier to install on new Python version:
pip install pycryptodome
And boom, it's done!

How can I fix this? any suggestions?

This issue tell you that pip repository can't find the (exact) version of the plugin you want install.
A workaround is too modify the requirements.txt file and take a more generic approach like this :
Instead of pip-plugin-name==version-number
do pip-plugin-name , this will install the most up to date version of this plugin hosted on pip server.
In your case : replace django-multi-captcha-admin==1.0.0 by django-multi-captcha-admin in the requirements.txt file.
If any version of this plugin is present on pip server, it will be installed.
