python3 -m venv venv-test

But when I do this , I get the error...

 File "venv-test/Scripts/activate", line 4
    deactivate () {
              ^ SyntaxError: invalid syntax

I opened the generated 'activate' file and this seems to be the part that's causing the problem but I'm not sure how to correct it.

deactivate () {
# reset old environment variables
if [ -n "${_OLD_VIRTUAL_PATH:-}" ] ; then
    export PATH
if [ -n "${_OLD_VIRTUAL_PYTHONHOME:-}" ] ; then
    export PYTHONHOME

Thanks in advance!
