      // When running `vp test --project unit*`, Vitest still initializes all projects (this is
      // expected  behavior see https://github.com/vitest-dev/vitest/issues/9849) and loads
      // `packages-private/vapor-e2e-test/vite.config.ts`. That config immediately imports
      // `vue/compiler-sfc`, but the package has not been built yet.
      // To work around this, we conditionally include the vapor e2e test project only when the
      // `VAPOR_E2E` env variable is set.
      // for Vitest VSCode extension, we can set this env variable in the `vitest.nodeEnv` config
      // to ensure the vapor e2e tests are included when running tests in VSCode.
      // "vitest.nodeEnv": {
      //   "VAPOR_E2E": "1"
      // },
