Try to update alternatives and set python 3.7 as default

Volbil, [15.06.20 14:17]
sudo add-apt-repository ppa:deadsnakes/ppa
sudo apt-get update
sudo apt-get install python3.7
sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.7 1
sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.5 2
sudo update-alternatives --config python3
pip3 install --upgrade setuptools
sudo apt-get install python3.7-gdbm
sudo apt install python3.7-dev

Volbil, [15.06.20 14:17]
This is how I usually install python 3.7

cryptozeny, [15.06.20 14:26]

pip3.7 confused
pip3.7 install -r requirements.txt

cryptozeny, [15.06.20 14:33]
pip3.7 install --ignore-installed PyYAML fixed

Volbil, [15.06.20 14:34]
You should use virtual enviroment

cryptozeny, [15.06.20 14:34]

seems works

Volbil, [15.06.20 14:34]
In this case there is won't be any conflicts

cryptozeny, [15.06.20 14:34]
[In reply to Volbil]
whats that?

Volbil, [15.06.20 14:35]
https://docs.python.org/3/tutorial/venv.html

cryptozeny, [15.06.20 14:38]
install python3.7 on ubuntu 16.04

sudo add-apt-repository ppa:deadsnakes/ppa
sudo apt-get update
sudo apt-get install python3.7
sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.7 1
sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.5 2
sudo update-alternatives --set python /usr/bin/python3.7
pip3 install --upgrade setuptools
sudo apt-get install python3.7-gdbm
sudo apt install python3.7-dev

if
you get this error, try pip3.7 install --ignore-installed PyYAML
ERROR: Cannot uninstall 'PyYAML'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.

[In reply to cryptozeny]
Second part is very wrong!

Volbil, [15.06.20 14:40]
Never do that

cryptozeny, [15.06.20 14:40]
[In reply to Volbil]
PyYAML?

Volbil, [15.06.20 14:40]
[In reply to cryptozeny]
--ignore-installed

Volbil, [15.06.20 14:40]
You should use venv instead

Volbil, [15.06.20 14:41]
python3 - venv venv
source venv/bin/activate

Volbil, [15.06.20 14:41]
In this case all dependencies for api server will be installed into venv folder, instead of globally

cryptozeny, [15.06.20 14:42]
i never installed PyYAML before. it seems default on 16.04

Volbil, [15.06.20 14:42]
[In reply to cryptozeny]
Problem is, you installed PyYAML for python 3.5

cryptozeny, [15.06.20 14:42]
you said 5.1, but in this case pip said 3.11 already installed

Volbil, [15.06.20 14:42]
And update it to python 3.7

Volbil, [15.06.20 14:43]
There is different PyYAML version for 3.5 and 3.7

Volbil, [15.06.20 14:43]
That's why there is conflict

cryptozeny, [15.06.20 14:43]
i removed pip3 requirements, and fresh installed for py3.7

Volbil, [15.06.20 14:43]
And that's why you should use venv

cryptozeny, [15.06.20 14:43]
how to use venv in this case??

Volbil, [15.06.20 14:44]
[In reply to Volbil]
.

cryptozeny, [15.06.20 14:44]
i never tried before

cryptozeny, [15.06.20 14:44]
just this?
python3 - venv venv
source venv/bin/activate

Volbil, [15.06.20 14:44]
Yes

Volbil, [15.06.20 14:44]
And install all dependencies from requirements.txt
