'eval' is not recognized as an internal or external command, operable program or batch file on windows npm script

$ npm run deploy:local

> backend@0.1.0 deploy:local
> eval "`aws-auth-helper ` lerna run deploy:sandbox --stream"

'eval' is not recognized as an internal or external command,
operable program or batch file.

Node version:

$ node --version
v15.11.0

NPM version:

$ npm --version
7.6.0

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

Solution

Since you are on a Windows environment, even if the shell you're executing from is bash, npm will likely be executing the run script in the default shell of Windows (PS now, I think?).

You could try modifying your package.json file in this way

Note that if bash is not in your PATH, you'll have to use the full path

{
//... other keys
  "scripts" : {
    //... other keys
    "deploy" : "bash -c \"eval `aws-auth-helper ` lerna run deploy:sandbox --stream\" "
  }
}
