An issue for vue2(<2.7) compiler with "transpile is not a function"

[twt898xu]

Describe the bug

when I use the latest version (0.18.5) with my vue2 product, it doesn't work
it will throw a "transpile is not a function" error
I found a problem in the code

this code on src/core/compilers/vue2.ts file

const transpile = (await importModule('vue-template-es2015-compiler'))
    .default

I think we don't need the .default. because the importModule method has parsed it

I also encountered this problem. Is there any good solution at this stage?

[twt898xu]

@wjw020206 you can downgrade to v0.17.0

@wjw020206 you can downgrade to v0.17.0

alright, thank you very much

@wjw020206 you can downgrade to v0.17.0

hi. I tried to use v0.17.0 but there were new problems, Prompt error: Typerror: Require (...). Default is not a function

module.exports = function unplugin() {
  return [
    require('unplugin-auto-import/webpack').default({
      imports: ['vue', 'vue-router', 'pinia'],
      eslintrc: {
        enabled: true
      },
      dts: 'src/typings/auto-imports.d.ts'
    }),
    require('unplugin-vue-components/webpack').default({
      dts: 'src/typings/components.d.ts',
      resolvers: [require('unplugin-icons/resolver').default()] // The error appears in this line
    }),
    require('unplugin-icons/webpack').default({
      compiler: 'vue2',
      scale: 1,
      defaultClass: 'inline-block',
      autoInstall: true
    })
  ];
};

you can remove the default() and try again

I tried it, the problem changed，Prompt error: Typerror: Require (...). Default is not a function

module.exports = function unplugin() {
  return [
    require('unplugin-auto-import/webpack').default({
      imports: ['vue', 'vue-router', 'pinia'],
      eslintrc: {
        enabled: true
      },
      dts: 'src/typings/auto-imports.d.ts'
    }),
    require('unplugin-vue-components/webpack').default({
      dts: 'src/typings/components.d.ts',
      resolvers: [require('unplugin-icons/resolver')]
    }),
    require('unplugin-icons/webpack').default({ // The error appears in this line
      compiler: 'vue2',
      scale: 1,
      defaultClass: 'inline-block',
      autoInstall: true
    })
  ];
};

This is the dependence I used in my current project

same as above, you don't need the default()

like

module.exports = function unplugin() {
  return [
    require('unplugin-auto-import/webpack').default({
      imports: ['vue', 'vue-router', 'pinia'],
      eslintrc: {
        enabled: true
      },
      dts: 'src/typings/auto-imports.d.ts'
    }),
    require('unplugin-vue-components/webpack').default({
      dts: 'src/typings/components.d.ts',
      resolvers: [require('unplugin-icons/resolver')()]
    }),
    require('unplugin-icons/webpack')({ // The error appears in this line
      compiler: 'vue2',
      scale: 1,
      defaultClass: 'inline-block',
      autoInstall: true
    })
  ];
};

};

Thank you very much, the problem is solved.
