virtualenv：无法安装模块

Question

I am trying to run some python scripts on HPC cluster. My scripts required some python modules that were not in the cluster and I do not have permission to install them (through sudo ). This is why I created a virtualenv (in my directory on the HPC cluster). I successfully installed numpy but cannot insall: re , collections , time , csv and some more. The error that I get is this: Could not find a version that satisfies the requirement csv (from versions: ) No matching distribution found for csv I am new to python and this seems completely weird to me, since I was following the steps found on two different sources. What should I do to fix it? Thank you!

Answer 1

That error usually means there are no packages with those names .

Actually, you do not need to install those packages ( they do not exist ). They are included in python's standard library. you should just import them like :

import csv
import re
