  • Some packages install, others show 'already satisfied'
  • Package doesn't get upgraded when you expected
  • Works but installation looks incomplete
  • Different messages for different packages
  • Want to upgrade but pip skips it

  3. pip not using --upgrade flag
  4. Cached installation from previous run

  6. Virtual environment has package from previous install
