In order for (other) people to help you, please clarify three things:

  1. which "the bash script" are you referring to? Always link to tutorials, guides and/or other things you are reading and/or following. Otherwise it's impossible to know what you are doing
  2. which OS are you using?
  3. what is the output of python --version?

Hi, 1. The bash script is from here. 2. I'm using the Ubuntu 18.04 OS. 3. The version is Python 2.7.17 Actually, I have tried again installing following with the tutorials, but there is also same error. Thx again.
