That looks like an unfair comparison between a badly written batch one liner and a full fledged bash script (I agree that cmd.exe is much more limited).
Why do you strip off the first 3 chars from is the folder name when uninstalling?

This batch might work:

@Echo off
for /D %%f in (*) do (
  If exist "%f\setup.py" (
    PushD "%%f"
    pip uninstall "%%f"
    pip install .
    PopD
  )
)
