What is the current behavior?

$ yarn add progress
yarn add v0.17.10
error Missing list of packages to add to your project.

Works for all other modules; a workaround is npm i --save progress and then yarn.

What is the expected behavior?

install and add the module

Environment

yarn v0.17.10
node 7.2.1
OS information is classified, sorry.

Same problem here. My environment:

• yarn v0.17.10
• node 6.9.1
• ubuntu 16.10

Thanks for the workaround @KenanSulayman. 👍

The issue is in src/cli/index.js, when commander parses args and progress becomes the first argument besides startArgs (node yarn), it is parsed as an option since --no-progress option is defined above.

A quick fix would be to add commandName back when parsing args, but that looks like a workaround: https://gist.github.com/iredchuk/689e7cf949e22c708b68befb7662855d

Didn't work with commander before, but this behaviour looks weird to me: the last case is what's happening here when the arg is lost due to the name collision with an option: https://gist.github.com/iredchuk/ab253c68a880d45e0ab99d853fc56ddc

Wonder if it's possible to change this via some commander settings, e.g. do not parse arg as option when it's not preceded with '--'?

workaround: yarn add -- progress, note space between -- and package name, the doubledash instructs yarn not to parse options after that point
