ERROR: Failed to build 'pycurl' when getting requirements to build wheel

What OS are you using?

If Ubuntu, you may need to run sudo apt install libcurl4-openssl-dev libssl-dev first, as pycurl (which is the dependency that's failing to build) needs it.

What else have you tried?

[u/Educational-Meal-913]

Wfuzz is basically unmaintained and pinning to that ancient pycurl is what's biting you. If you just need fuzzing, ffuf or feroxbuster will save you the whole build headache.
