I usually use virtualenv and virtualenvwrapper for creating virtualenvironments for my projects. On trying to create a new virtualenvironment using the following command:
mkvirtualenv -a . -p python3.7 venv
I get the following error message:
Exception in thread Thread-1:

Setting project for cosine to /home/ubuntu/cosine_similarity
With the virtualenvironment being created still, on running :
pip -V
I get
pip 20.1 from /home/ubuntu/.local/lib/python3.6/site-packages/pip (python 3.6)
Which is pip associated with the default python version on the server and therefore, I uninstalled python3.7, and on running python3.7
on my terminal got:
Command 'python3.7' not found, but can be installed with:
sudo apt install python3.7-minimal
Thus on the assumption that python3.7 wasn't installed properly, I again re-installed it using the ppa from deadsnakes as follows:
sudo add-apt-repository ppa:deadsnakes/ppa
sudo apt-get update
sudo apt install python3.7
But sadly I am still running into the same error, I am using poetry on top of the virtualenvironment and on running the following:( I have the poetry.lock file)
poetry install
I get the following error message:
[CalledProcessError]
Command '['/home/ubuntu/.cache/pypoetry/virtualenvs/cosine-similarity-SzdRNlpw-py3.7/bin/python', '-Im', 'ensurepip', '--upgrade', '--default-pip']' returned non-zero exit status 1.
Would be great if someone can explain why this is happening and how to solve this in turn, thanks.
[EDIT]
Adding more information when I use -p python3.6
, I don't get any such permission errors and my virtualenvironment is created successfully.
For additional information, I installed python3.8 on the system using the above ppa by deadsnakes* and then attempted to create a virtualenvironment with python3.8.
Command
mkvirutalenv -a . -p python3.8 venv2
The output in stdout is as follows:

Before you try this solution, try running sudo su
Then repeat your solution,... If it works cool. Else
Part 2 ======>
Check your python version.
python --version
Find all python within python
ls /usr/bin/python*
If python 3.7 is part of the listed path, cool.
Set python default path
alias python='/usr/bin/python3.7'
Re login your source
. ~/.bashrc
Confirm that your version of python has changed python --version
Then install virtual environment
pip install virtualenv
Then create a virtual environment
virtualenv venv
And activate it
source venv/bin/activate
