for scraping proxy ip by python i have writes this code before,

now when i want to run it in Pycharm i get this error:

/usr/bin/python2.7 /snap/pycharm-community/179/plugins/python-ce/helpers/pydev/pydevd.py --multiproc --qt-support=auto --client 127.0.0.1 --port 38097 --file /media/so/ACAC8B5FAC8B2346/soheil/web_site_root/ieee/all_functions/configs/proxy_scraper/IPProxyScraper.py

So i asked here for solution.

Thanks

Answer 1

the problem was from pycurl so, i have tried this instruction:

I had the same problem. I was able to install it with easy_install instead:

easy_install pycurl

For easy_install, see setuptools.

and then i get htis error:

so@so-notebook:~$ sudo easy_install pycurl
