How to fix could not find a version that satisfies the requirement django-multi-captcha-admin==1.0.0-CodePudding

I'm trying to set up a django project on my local. I've created a virtualenv. when I try install the requirements with:

pip install -r requirements.txt

I'm getting an error:

How can I fix this? any suggestions?

CodePudding user response：

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.
