Please give the required information as described in Contributing.md

I need to now:

• [ ] how are you using readchar? What code produces the error?
• Information about your system:
  • [x] your OS
  • [ ] your Python version and implementation (use python --version)
  • [ ] the version of readchar you use (use pip show readchar)

Closing do to lack of information
