The best approach is probably to just check the script beforehand, something like the following
```bash
grep import script.py
```
should list all imports and you can then evaluate and install them.

If you really want to automate things you can write a short shell script to loop & install modules for example this one in bash:
```bash
#!/usr/bin/env bash
while :;
do
  { STDERR="$( { ${@}; } 2>&1 1>&3 3>&- )"; } 3>&1;
  if [[ $? -eq 0 ]]; then
    break
  else
    module=$(printf '%s' "$STDERR" | grep ModuleNotFoundError | cut -d\' -f 2)
    pip install $module
  fi
done
```

when saved as `install.sh` in the current directory can be used as `bash install.sh python script.py`

If you create a virtual environment with something like `python -m venv env; source env/bin/activate` (which you should do to not pollute your global packages anyways) before you can generate a `requirements.txt` with `pip freeze > requirements.txt` afterwards and save yourself the hassle in future.
