When installing Python3 packages on macOS X 10.15 Catalina using pip install -r requirements.txt
I am getting this error:

So It fails on installing PycURL because it cannot find the openssl
include directory.
I have first added cryptography==37.0.4
to the requirements.txt
file but then I got:
src/pycurl.h:178:13: fatal error: 'openssl/ssl.h' file not found
Then I have tried installing latest openssl
with:
brew update
brew install openssl
brew link --force openssl
ln -s /usr/local/opt/openssl/lib/libcrypto.3.dylib /usr/local/lib/
ln -s /usr/local/opt/openssl/lib/libssl.3.dylib /usr/local/lib/
ln -s /usr/local/Cellar/openssl/3.0.4/bin/openssl /usr/local/bin/openssl
But it didn't help.
I also tried:
export PYCURL_SSL_LIBRARY=openssl
export LDFLAGS="-L/usr/local/opt/openssl@3/lib"
export CPPFLAGS="-I/usr/local/opt/openssl@3/include"
pip install --no-cache-dir --compile --ignore-installed --install-option="--with-openssl" pycurl
But also with no success. Any help on this?

What eventually helped was:
- Remove
pycurl
from therequirements.txt
file - Install
openssl
with:brew install openssl
- Find
openssl
installation directory with
$ brew --prefix openssl
/usr/local/opt/openssl@3
$ ls -la /usr/local/opt/openssl@3
lrwxr-xr-x 1 runner admin 25 Jul 6 09:13 /usr/local/opt/openssl@3 -> ../Cellar/openssl@3/3.0.4
- Install PycURL specifying inline the above
openssl
install directories like this:
PYCURL_SSL_LIBRARY=openssl LDFLAGS="-L/usr/local/Cellar/openssl@3/3.0.4/lib" CPPFLAGS="-I/usr/local/Cellar/openssl@3/3.0.4/include" pip3 install --no-cache-dir pycurl
- Now the PycURL installs without any problem:
