How to fix "#error architecture not supported" when installing pycurl with Python 3.8.2 on macOS 10.15?

Question:

I am trying to install pycurl 7.44.1 and it fails with a

#error architecture not supported

  • Python 3.8.2
  • libcurl 7.64.1
  • macOS 10.15.7 (Catalina)

Any idea what might be causing this? I’ve tried also installing with easy_install, and it looks like it had gone much smoother, but after trying to import it will still error out as if it had not been installed.

Update: Installing with the following flag seems to get passed the unsupported architecture issues:

ARCHFLAGS="-arch x86_64" pip install pycurl

However, upon trying to import/run in Python it still fails with an openssl issue:

    Python 3.8.2 (default, Dec 21 2020, 15:06:04)
[Clang 12.0.0 (clang-1200.0.32.29)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import pycurl
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: pycurl: libcurl link-time ssl backends (secure-transport, openssl) do not include compile-time ssl backend (none/other)

This seems to have fixed the unsupported architecture and openssl issue now:

ARCHFLAGS="-arch x86_64" pip install --compile --install-option="--with-openssl" pycurl
Answered By: Zak44

Recently (July 2023) ran into this issue too, with the following setup for my Intel Macbook.

VS Code 1.79.2
Python 3.10.5 venv
pycurl 7.45.2
macOS Ventura 13.4.1
openssl 3.1

I solved my issues with help from the other comments and adding ALL of the following lines to my bash_profile

# Settings for Pycurl
export LDFLAGS="-L/usr/local/opt/[email protected]/lib"
export CPPFLAGS="-I/usr/local/opt/[email protected]/include"
export PKG_CONFIG_PATH="/usr/local/opt/[email protected]/lib/pkgconfig"
export PATH="/usr/local/opt/[email protected]/bin:${PATH}"
export PYCURL_SSL_LIBRARY=openssl
export ARCHFLAGS="-arch x86_64"
