IE9 doesn't support History API, use hash mode or fallback.

//nuxt.config.js
module.exports = {
  router: {
    mode: 'hash',
    // or
    fallback: true
  }
}

@clarkdo vue-router had solved this problem on v3.0.1 [https://github.com/vuejs/vue-router/tree/v3.0.1] . but nuxtjs is use to the old version v2.7.0 . When will the next version be updated to solve this problem in IE9？

Please refer https://github.com/nuxt/nuxt.js/issues/2142, we're really work hard on the new release. 😸

@djune i have tried upgrade vue-router to v3.0.1, and still got that error.

the way to upgrade it is just delete the package in node_modules and reinstall it, and upgrade other vue packages

@huanyu I resolved by this:
window.history.replaceState = window.history.replaceState || function(){};

@clarkdo Thank you. It helped me a lot. Fallback is a great way to do it.
