what is the error here how can i resolve this.

https://github.com/fhamborg/news-please says that adopt the config section in newsplease/examples/commoncrawl.py. what does this mean?
i have copied the configurations from this file and pasted in config.cfg which is present in the newsplease/config directory. is this what thay have instructed? or i have made a mistake here.

i am using python 3.6. i have only one python installed in my machine.

Answer 1

this error is because of the libraries being used by the newsplease. mistake is made when we manually install every library, while installing focus on the versions of packages. version info of every library is given in setup.py file. install exact version given in setup.py file. now there may be problems while executing the setup.py.

so use this command -

python3 setup.py install

if you need to uninstall all the previous verions of installed packeges then run -

pip3 freeze --user | xargs pip3 uninstall -y
