Compile issue

While run serve in Vue 2 warnings like:

• "export 'createApp' was not found in 'vue'
• "export 'default' (imported as 'VueGraph') was not found in 'vue-graph'
• "export 'h' was not found in 'vue'
  These warning lead to an error on the browser which show like there is a missing semicolon or something. The error says :
  Uncaught TypeError: Object(...) is not a function
  at eval (index.js?aa17:9)
  at Module../node_modules/vue-graph/bundles/index.js
