Flags are not working with typescript ^4.1.3

os: windows10 node: v10.15.1 terminal: WSL

const options = {
  flags: {
    rainbow: {
     type: 'boolean',
     alias: 'r'
    }
  }
}

meow(`...`, options)

The root cause is create-ink-app always using the latest version of meow and @sindresorhus/tsconfig. create-ink-app is using a simple install script to install them without a specific version. By default, you will get the latest version.

Since meow@10.0.0, we moved our package to ESM.

I will help create-ink-app move their package to ESM. It will take some time because there are some blocking dependencies that need to be moved to ESM as well.

Before that, you could downgrade your meow to 9.0.0 or lower manually (just modify your generated code and reinstall dependencies).

Update:
I submitted a quick fix for CommonJS modules.
