how to profile PyPy with vmprof?

Question

I read the vmprof doc in https://vmprof.readthedocs.io/en/latest/vmprof.html And I try to to prof pypy, with the cmd:

 pypy -m vmprof --web  hello.py

Then i return that:

/usr/bin/pypy: No module named vmprof

I Try

pip install vmprof 

then

 pypy -m vmprof --web  hello.py

But it doesn't work yet! I am totally confused, can somebody tell me what should i do??? where's the right way?

------- the next day update ---------- aha, now I find the way out!

clone this git repo

https://github.com/vmprof/vmprof-python.git

and that

cd vmprof
cd vmprof-python/
pypy setup.py install

Now you find your pypy have the module vmprof now !

but i meet a new problem, somebody knows how to solve it ?

xxx@yyy:~$  pypy -m vmprof  hello.py

Are you sure your pip corresponds to pypy and not vanilla python? Try

pypy -m pip install vmprof
