[PROBLEM] Installing python modules fails

[postcd]

Hello,

I have tried to install some modules like "$ sudo python3 -m pip install coincurve"
but it fails, as shown in the output here.

Please what is likely wrong and what to try to install that module/s?

Actually i am trying to install multiple modules from requirements.txt file:

Quote:gevent==1.4.0; python_version <= "3.6"
greenlet==0.4.16; python_version <= "3.6"
gevent>=20.9.0; python_version >= "3.7"
msgpack>=0.4.4
base58
merkletools
rsa
PySocks>=1.6.8
pyasn1
websocket_client
gevent-ws
coincurve
maxminddb

(sudo python3 -m pip install -r ./requirements.txt)
