ERROR: Command errored out with exit status 1: python setup.py egg_info Check the logs for full command output.
The command '/bin/sh -c pip3 install -r requirements.txt' returned a non-zero code: 1

I tried to find and remove goslate module, but I couldn't find. Maybe this goslate is required by one of my modules.

The error says: "newlines not allowed" - do you have an empty line at the end of requirements.txt? — Nir Alfasi, Jan 17 '21 at 11:06
if @NirAlfasi's answer didn't help you, try removing googletrans. — Volpym, Jan 17 '21 at 11:35
@NirAlfasi I tried removing extra line, but GitHub is automatically adding it. — lockdown timepass, Jan 17 '21 at 11:47
This seems to be a problem with the goslate package; I get the error installing on Python 3.9, but not on Python 2.7 PyPI says last relase 2016, maybe it's abandonware. — snakecharmerb, Jan 17 '21 at 11:48
@snakecharmerb Actually goslate is not on my requirements to remove it, maybe one of my modules has it in its requirements — lockdown timepass, Jan 17 '21 at 11:51

Create a list of all the dependencies and run the following code.

for l in list:
 print('checking for {}'.format(l))
 url = 'https://pypi.org/pypi/{}/json'
 json = requests.get(url.format(l)).json()
 if json['info']['requires_dist'] is not None:
         if 'goslate' in json['info']['requires_dist']:
                 print('found one ! : {}'.format(l))

this will check all if goslate is in any of the modules that you need.

got help from here How to list dependencies for a python library without installing?

It worked. But I got error when taking requests as json. So I took request as text and used if statement.Thanks a lot. — lockdown timepass, Jan 17 '21 at 14:15
