After installing erpnext through bitnami stack I cant use bench

Traceback (most recent call last):
  File "/usr/local/bin/bench", line 5, in <module>
    from pkg_resources import load_entry_point
  File "/usr/lib/python2.7/dist-packages/pkg_resources.py", line 2749, in <module>
    working_set = WorkingSet._build_master()
  File "/usr/lib/python2.7/dist-packages/pkg_resources.py", line 444, in _build_master
    ws.require(__requires__)
  File "/usr/lib/python2.7/dist-packages/pkg_resources.py", line 725, in require
    needed = self.resolve(parse_requirements(requirements))
  File "/usr/lib/python2.7/dist-packages/pkg_resources.py", line 628, in resolve
    raise DistributionNotFound(req)
pkg_resources.DistributionNotFound: bench==2.0.0

Better used the script it’s easy

You can actually still use bench but as always bitnami limits the use of internal scripts to bitnami scripts, take a look here:

Thanks for the suggestions…I manually installed ERPNext and now its working fyn…
