I am using VSCode Bash terminal. It had been working just fine but then I started getting this error. Have tried both the bash terminal and javascript terminal.

If I just type "eval" in the bash terminal, it works okay. While running through npm script it does not.

if you're running in Windows, the default shell we use to run scripts with is cmd.exe which does not have an eval. you can override this to use bash by running npm config set script-shell=bash

let me know if that works for you. admittedly there's an opportunity for a bit of enhancement here where we could potentially default to the currently running shell instead of an operating system specific one, but that's something we would have to take through our RFC process detailed here: https://github.com/npm/rfcs
