When I try to activate my virtualenv from GIT bash mingw32 I do not get the expected response.
NOTE: py is the folder for Python projects in my Google
py
On Windows10, you could go in the directory of your virtualenv where the Scripts folder is placed then enter the below command
source ./Scripts/activate
Note the .(dot) without this it was giving error to me when I use it like above mentioned then the solution provided by Pierre worked for me.
