As a shell function:
pu() {                                                                                                                 ~
  pip3 list -o   |
  sed "1,2 d"    |
  cut -d ' ' -f1 |
  xargs -n1 pip3 install -U
}

While not to the degree of say python, whitespace matters often in shell;
You have an extra space after the name of the alias pu, so the =word triggered a different
feature of zsh that expands the path to a command. in this case "pip3 list -o | sed 1,2"
once you remove the space you still have the problem of not quoting correctly.

alias pu='pip3 list -o | sed "1,2 d" |cut -d '\'' '\'' -f1 |  xargs -n1 pip3 install -U'

Is how to quote that command properly, which is less readable than a function is in my opinion.
