Vue.js: Failed to generate render function

I try to run a simple Vue.js, but I constantly receive the following error:

[Vue warn]: It seems you are using the standalone build of Vue.js in an environment with Content Security Policy that prohibits unsafe-eval. The template compiler cannot work in this environment. Consider relaxing the policy to allow unsafe-eval or pre-compiling your templates into render functions.

main.js:3180 [Vue warn]: Failed to generate render function: EvalError: Refused to evaluate a string as JavaScript because 'unsafe-eval' is not an allowed source of script in the following Content Security Policy directive: "default-src 'self'". in

with(this){return _c('div',{attrs:{"id":"app"}})}

(found in )

Yet, I can't understand what is causing this error. I don't seem to use any dynamic templates and everything should be pre-compiled. Here is the code of my application:

import Vue from 'vue'
import VueRouter from 'vue-router'

const Home = Vue.component('home-component', {
  render() {
    return <div>
      <router-link to="/users">Users</router-link>
      <router-link to="/about">About</router-link>
    </div>
  }
})

const Users = Vue.component('users-component', {
  render() {
    return <p>Users</p>
  }
})

const NotFound = Vue.component('not-found-component', {
  render() {
    return <p>Not Found</p>
  }
})

const routes = [
  { path: '/', component: Home },
  { path: '/users', component: Users }
]

const router = new VueRouter({
  routes
})

const app = new Vue({
  router
}).$mount('#app')

And here is how I process JavaScript files in my gulpfile:

const paths = {
  main: 'web/javascript/src/main.js',
  allJs: 'web/javascript/**/*.{js,vue}',
  resultJs: 'public/assets/javascript/main.js',
};

gulp.task('scripts', function() {

  return browserify(paths.main)
    .transform(babelify, { presets: ['es2015'], plugins: ["transform-runtime"] })
    .transform(vueify)
    .bundle()
    .pipe(fs.createWriteStream(paths.resultJs))
}

There are seem to be many similar questions on StackOverflow, but none of them helped me.

The broweser is throwing Content Security Policy (CSP) error, to get around this issue you should consider switching to the runtime-only build, which is fully CSP-compliant. https://v2.vuejs.org/v2/guide/installation.html#CSP-environments

Also, You have return incorrectly written. It should return jsx in pair of paranthesis (). The code below should help

import Vue from 'vue'
import VueRouter from 'vue-router'

const Home = Vue.component('home-component', {
  render(h) {
    return(
    <div>
      <router-link to="/users">Users</router-link>
      <router-link to="/about">About</router-link>
    </div>
    )
  }
})

const Users = Vue.component('users-component', {
  render(h) {
    return(
      <p>Users</p>
    )
  }
})

const NotFound = Vue.component('not-found-component', {
  render(h) {
    return(
      <p>Not Found</p>
    )
  }
})

const routes = [
  { path: '/', component: Home },
  { path: '/users', component: Users }
]

const router = new VueRouter({
  routes
})

const app = new Vue({
  router
}).$mount('#app')
