Can I change the default Python 3.6.5 on WSL Ubuntu 18.04 to 3.7? So when I check
python3 --version I get
3.7.x so I can use that version with pip3 as well. Thanks
Here's the steps to change your
python3 command to point to your
python3.7 version (assuming you already have 3.7 installed). Please adjust paths as needed for your environment
# 1 - Identify your location of `python3` using the `which` command which python3 # returns something like /usr/local/bin/python3 # 2 - Identify your location of `python3.7` using the `which` command which python3.7 # returns something like /usr/local/bin/python3.7 # 3 - Get directory listing of python3 folder (from 1 above) # using grep to filter results containing 'python' ll /usr/local/bin | grep -i python # returns something like below - notice the arrow after python3 # the arrow indicates a symbolic link lrwxrwxrwx 1 root root 18 Jul 4 2018 python3 -> /usr/bin/python3.6* -rwxr-xr-x 2 root root 14777608 Nov 3 00:36 python3.7* -rwxr-xr-x 2 root root 14777608 Nov 3 00:36 python3.7m* -rwxr-xr-x 1 root root 3097 Nov 3 00:37 python3.7m-config* -rwxr-xr-x 1 root root 4522328 Feb 22 17:24 python3x* # 4 - Test creating a symbolic link using sudo to get root privileges # enter password if/when prompted sudo ln -s /usr/local/bin/python3.7 /usr/local/bin/test37 # 4 - verify test test37 --version # Desired output Python 3.7.1 # 5 - remove test and python3 sudo rm /usr/local/bin/test37 sudo rm /usr/local/bin/python3 # 6 - creating python3 symbolic link using sudo to get root privileges # enter password if/when prompted sudo ln -s /usr/local/bin/python3.7 /usr/local/bin/python3 # 7 - verify python3 --version # Desired output Python 3.7.1
Of course the pythonic thing to do is to use virtual environments.
