Today I try to install Django in a Python virtual environment by using the command-"sudo apt-get install python3-venv", but there raised a error report: "E: Unable to locate package python3-venv". After I search in the stack overflow, i find the answer to solve this error by using the command: " sudo apt-get install python3.4-venv".
