Installed version of wrangler not being used with v3.7.0 using yarn v1.22.22 in CI

[acusti]

i’m very excited for the changes introduced in v3.7.0 to use existing wrangler installation when appropriate (from #271). my app relies on getPlatformProxy so it cannot be deployed with any version of wrangler that doesn’t include that API. however, in my case, the logic to check that existing install and version if somehow falling through to the ⚠️ Wrangler not found or version is incompatible. Installing... fallback logic.

here is my output from the workflow run, which shows that i am using yarn v1.22.22 and shows that /usr/local/bin/yarn wrangler --version, as invoked by wrangler-action, is returning the version number (3.63.2) correctly:

my hypothesis is that the issue is due to the fallback regex starting with the “start of string” token (/^):

stdout.match(/wrangler (\d+\.\d+\.\d+)/) ?? stdout.match(/^(\d+\.\d+\.\d+)/);

i’m not sure how stdout is derived, but if it includes anything before the version output (e.g. \n3.63.2, or even /home/runner/work/outlyne/outlyne/node_modules/.bin/wrangler --version\n3.63.2), the regex won’t match it.

the most obvious solution, then, is to use multi-line mode so that ^ matches the start of every line as well as the start of the string:

		const versionMatch =
 			stdout.match(/wrangler (\d+\.\d+\.\d+)/) ??
 			stdout.match(/^(\d+\.\d+\.\d+)/);

in case it’s helpful, this is my yaml from the workflow file itself:

    deploy:
        name: 🚀 Deploy
        runs-on: ubuntu-latest
        needs: [lint, typecheck, vitest]
        # only deploy main branch on pushes
        if: ${{ github.ref == 'refs/heads/main' && github.event_name == 'push' }}

        steps:
            - name: ⬇️ Checkout repo
              uses: actions/checkout@v4

            - name: ⎔ Setup node
              uses: actions/setup-node@v4
              with:
                  cache: yarn
                  cache-dependency-path: ./yarn.lock
                  node-version: 20

            - name: 📥 Install deps
              run: yarn

            - name: 🚀 Deploy Production
              uses: cloudflare/[email protected]
              with:
                  apiToken: ${{ secrets.CLOUDFLARE_API_TOKEN }}
