pip install produces the following error on mac: error: command 'gcc' failed with exit status 1
I dealt with this problem for a while while trying to install another library that relies on openssl in a MacOS virtual env.
Mac has deprecated openssl in favor of their own SSL. So what you need to do is:
brew install openssl
or if it is already installed,
brew reinstall openssl
Now you need to to change the LD and CPP Flags. Refer to the openssl reinstall dialog. Should tell you where the commands!
openssl is keg-only, which means it was not symlinked into /usr/local, because Apple has deprecated use of OpenSSL in favor of its own TLS and crypto libraries.
If you need to have openssl first in your PATH run:
echo 'export PATH="/usr/local/opt/openssl/bin:$PATH"' >> ~/.bash_profile
For compilers to find openssl you may need to set:
export LDFLAGS="-L/usr/local/opt/openssl/lib"
export CPPFLAGS="-I/usr/local/opt/openssl/include"
For pkg-config to find openssl you may need to set:
export PKG_CONFIG_PATH="/usr/local/opt/openssl/lib/pkgconfig"

So I tried to install a package from PyPI with the following command:
sudo pip3 install switcheo
But it fails to install the package in the end.
Error checking for conflicts.

This is the full output in the terminal after running the pip install line. I found some solutions for linux, but there are not a lot of posts here for mac users.

David about 5 yearsAwesome thanks for the reply, I had made a separate post with a similar question and still no concrete solution. This seems to do the trick.

Moonero about 5 yearsGreat! Took me a while to figure this out as well.
