Nuxt Generate failure due to invalid alias setting

[aimeb1]

Environment

OS: Windows-WSL2-Ubuntu 22.04
Node: 14.17 Docker Image: FROM mcr.microsoft.com/devcontainers/javascript-node:14
Project Version: V1.5.0 https://github.com/vuestorefront-community/spree
Package Manager: yarn
Builders: webpack,babel,rollup

User Config:

target: 'static',
// ssr: true,

buildModules: [
['@vue-storefront/nuxt-theme', {
routes: false,
generate: {
replace: {
apiClient: '@vue-storefront/spree-api',
composables: '@vue-storefront/spree'
}
}
}]

router: {

extendRoutes(routes, resolve) {
  routes.splice(0, routes.length);
  // routes.push(...getRoutes());
  routes.push({
    name: 'custom',
    path: '*',
    component: resolve(__dirname, '_theme/pages/HomePre.vue')
  })
}

},

generate: {
crawler: false,
routes: ['/HomePre']
}

Runtime Modules:
@vue-storefront/nuxt
nuxt-i18n
cookie-universal-nuxt
vue-scrollto/nuxt
@vue-storefront/middleware/nuxt

Build Modules:
@nuxtjs/composition-api/module
@nuxt/typescript-build
@nuxtjs/google-fonts
nuxtjs/pwa
@nuxtjs/style-resources
@vue-storefront/spree/nuxt
@vue-storefront/nuxt
@vue-storefront/nuxt-theme

Reproduction

Using V1.5.0 from V1.5.0 https://github.com/vuestorefront-community/spree along with nuxt config changes above. I modified root package.json scripts to include a generate command:

"scripts": {
"generate": "yarn build:api-client && yarn build:composables && yarn generate:theme",
"generate:theme": "cd packages/theme && yarn generate",

I run 'yarn generate' and get the following in the log which seems 'ok' except maybe for the warning that @vue-storefront/nuxt should only be specified once (it is included in both the Modules and Build Modules).

Describe the bug

The errors in the console come during the build step of the yarn generate command.
I included only the 1st 'Module not found' error in the log below although there are many others.

Additional context

After some debugging I noticed the error seems to come down to a bad definition of the ~ alias. The imports in the default.vue layout references this alias:
import AppFooter from '~/components/AppFooter.vue';

The generate.js file from @vue-storefront/nuxt-theme defines these aliases:

  this.extendBuild((config) => {
    delete config.resolve.alias['~'];
    config.resolve.alias['~/middleware'] = path.join(projectLocalThemeDir, path.sep + 'middleware');
    config.resolve.alias['~/components'] = path.join(projectLocalThemeDir, path.sep + 'components');
    config.resolve.alias['~/assets'] = path.join(projectLocalThemeDir, path.sep + 'assets');
    config.resolve.alias['~'] = path.join(projectLocalThemeDir);
  });

However, the projectLocalThemeDir variable has a value of:
"/app/packages/theme/node_modules/.cache/nuxt"

This directory does not contain the AppFooter.vue. Shouldn't this variable be set to:
"/app/packages/theme"?

Making this change to index.js appears to fix the issue:

  // const projectLocalThemeDir = this.options.buildDir.replace('.nuxt', targetDirectory);
  const path = require('path');
  const projectLocalThemeDir = path.join(this.options.rootDir, path.sep + targetDirectory);
