Can Not Activate Environment

[hammer]

I think I created an environment correctly sometime in recent past but I can not get it to activate now. Below is command result and my directory tree. I know this is basic but what am I missing?
env is the environment name. I 1st tried the shorter $ source env/bin/activate with same results.
If i look in the env directory it has a bin folder and a activate and Activate.ps1 text file.

mark@mark-Latitude-E7240:~$ source MyComputer/mark/Python_Environments/env/bin/activate
bash: MyComputer/mark/Python_Environments/env/bin/activate: No such file or directory
mark@mark-Latitude-E7240:~$

Here a basic run

# Make
tom@tom-VirtualBox:~$ python -m venv my_env
# Cd in
tom@tom-VirtualBox:~$ cd my_env/
# Activate
tom@tom-VirtualBox:~/my_env$ source bin/activate
(my_env) tom@tom-VirtualBox:~/my_env$ which python
/home/tom/my_env/bin/python

Let say i'm not in my_env folder and want to activate,then have to give path to folder.

tom@tom-VirtualBox:~$ source my_env/bin/activate
(my_env) tom@tom-VirtualBox:~$ pip -V
pip 21.2.4 from /home/tom/my_env/lib/python3.10/site-packages/pip (python 3.10)

(my_env) tom@tom-VirtualBox:~$ deactivate
# Outside(deactivate) pip use Python version on OS
tom@tom-VirtualBox:~$ pip -V
pip 21.2.4 from /home/tom/.pyenv/versions/3.10.2/lib/python3.10/site-packages/pip (python 3.10)

When you build an environment, you do so against a particular version of python. If that version goes away (either manually or because some package manager upgrades python and thinks you don't need the old version any longer), then the virtual environment can't find it any longer and you get that message.

Either put the original version back on the box or recreate your virtual environment against whatever version of python is now installed.

Thank you both. Through above direction i resolved my issue. I checked and the version was still the same, however; when I changed my directory to where my environment was, the activation worked.
I know now to be in the directory as the environment i am trying to activate.

You don't need to be in the same directory, you just need to specify the path.

You don't need to be in the same directory, you just need to specify the path.

How so? Shouldn't the activation script provide the path?

No when outside of environment folder must specificity path to folder.

# Can not find it
tom@tom-VirtualBox:~$ source bin/activate
bash: bin/activate: No such file or directory

# If give path ok
tom@tom-VirtualBox:~$ source my_env/bin/activate
(my_env) tom@tom-VirtualBox:~$ deactivate
tom@tom-VirtualBox:~$

Same on windows but there there is no source,so then just give path to activate.bat on the environment that want to activate.
Let say i'm in root C:\ and want to activate a environment on G:\ drive.

C:\
λ G:\div_code\flaskex_env\Scripts\activate.bat

(flaskex_env) C:\
λ pip -V
pip 21.1.1 from g:\div_code\flaskex_env\lib\site-packages\pip (python 3.9)

(flaskex_env) C:\
λ deactivate
C:\
