can`t pass command line args using lerna

I try run the script from the root but got the error:

ERR! lerna Unknown argument: d

the command from root package.json:

"start:scripts:api-football:start:collectDayMatches:dev": "lerna run start:collectDayMatches:dev --stream"

try run yarn start:scripts:api-football:start:collectDayMatches:dev -- -d 2002-02-02

Solution

  • It seems you are trying to pass command arguments to the npm script of each package.

    For example:

    packages/pkg-a/package.json:

    "scripts": {
  "start:collectDayMatches:dev": "ls"
}

    root package.json:

    "scripts": {
  "start:scripts:api-football:start:collectDayMatches:dev": "lerna run start:collectDayMatches:dev --stream"
}

    Let's pass the -a option to the ls command.

    You should run the npm script with three double-dash (--) like this:

    [main] ⚡  yarn start:scripts:api-football:start:collectDayMatches:dev -- -- -- -a
yarn run v1.22.10
warning From Yarn 1.0 onwards, scripts don't require "--" for options to be forwarded. In a future version, any explicit "--" will be forwarded as-is to the scripts.
$ lerna run start:collectDayMatches:dev --stream -- -- -a
lerna notice cli v3.22.1

    As you can see, the final command is ls "-a".
