  <p>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.</p>
  <p>Update: Installing with the following flag seems to get passed the unsupported architecture issues:</p>
  <pre><code>ARCHFLAGS=&quot;-arch x86_64&quot; pip install pycurl
  </code></pre>
  <p>However, upon trying to import/run in Python it still fails with an openssl issue:</p>
  <pre><code>    Python 3.8.2 (default, Dec 21 2020, 15:06:04)
  [Clang 12.0.0 (clang-1200.0.32.29)] on darwin
  Type &quot;help&quot;, &quot;copyright&quot;, &quot;credits&quot; or &quot;license&quot; for more information.
  &gt;&gt;&gt; import pycurl
  Traceback (most recent call last):
