find something that may be default setup bug on kubuntu env

[Valkierja]

my system is a clean kubuntu20.04

when I exactly follow the README file install ROPgadget,I got some problems,which have been resolved by following issue#106(#106 https://blog.csdn.net/qq_31990441/article/details/103534937

but I think the problems can be auto-solve by changing setup.py so I re-raise issue 106 as this issue

(BTW,English is not my first language ,please forgive my spelling or syntax mistakes.)

the following is what I did

sudo pip install capstone
git clone
cd ROPgadget/
sudo python3 setup.py install
$ ROPgadget -h
Traceback (most recent call last):
  File "/usr/local/bin/ROPgadget", line 4, in <module>
    __import__('pkg_resources').run_script('ROPGadget==6.6', 'ROPgadget')

    self.require(requires)[0].run_script(script_name, ns)

Installing ROPgadget via pip should work fine:

sudo -H python3 -m pip install ROPgadget
