 > Do you also have py36-readline installed? Having both python36 (itself)
 installed +readline (variant) and py36-readline (the readline python
 package) installed at the same time can cause that, if I recall. Use one
 or the other.

 I removed `py36-readline` and installed `python36 +readline` and I don't
 get this error anymore. Thanks, Eric!
