Error installing Z2Pack 2.1.1

[Rajdeep Banerjee]

Dear sir,
              as you suggested I installed python3 setuptools and the
z2pack got installed with the pip command. The last few lines are as
follows:

...

Could not find .egg-info directory in install record for z2pack==2.1.1 from
file:///home/rajdeep/soft/Z2Pack-master-2.1.x

Successfully installed numpy scipy decorator blessings sortedcontainers
msgpack-python fsc.locker fsc.export fsc.formatting fsc.iohelper z2pack
Cleaning up...



Is the warning about "egg-info directory" anything serious to care about or
I can just ignore it? Thank you very much for your help.

best regards,
Rajdeep
