Question

我无法启动我的Vue.js应用程序

错误是：

import java.util.*;
import java.util.stream.*;

class Rank {

    public static String nthRank(String st, Integer[] we, int n) {
      System.out.println("\n\n\nNames: "+st+" weights: "+Arrays.toString(we)+" n: "+n);

      if(st.isEmpty()) return "No participants";
      String[] names = st.split(",");
      if(n > names.length) return "Not enough participants";

      String alphabet = "abcdefghijklmnopqrstuvwxyz";
      int sum = 0;
      Map<String, Integer> map = new HashMap<String, Integer>();

      for(int i = 0; i < names.length; i++){
        String currentName = names[i];
        sum += currentName.length();
        for(int j = 0; j < currentName.length(); j++){
          char currentChar = Character.toLowerCase(currentName.charAt(j));
          sum += alphabet.indexOf(currentChar) + 1;
        }
        map.put(currentName, sum*we[i]);
        System.out.println("Map: "+map.toString());
        sum = 0;
      }

      Comparator<Map.Entry> outerComparator = (pair1, pair2) -> {
         if ((int)pair1.getValue() > (int)pair2.getValue()){
            return 1;
          }else if ((int)pair1.getValue() < (int)pair2.getValue()){
            return -1;
          }else{
            return pair1.getKey().toString().compareTo(pair2.getKey().toString());
          } 
       };

      map = map.entrySet().stream()
            .sorted(Map.Entry.comparingByValue(MapComparator.compare()))
            .collect(Collectors.toMap(
              Map.Entry::getKey, Map.Entry::getValue, (e1, e2) -> e1, LinkedHashMap::new));

      System.out.println("\n\nSorted Map: "+map.toString());

      return map.keySet().toArray()[n-1].toString();
    }

    class MapComparator implements Comparator<Map.Entry> { 

        @Override
        public int compare(Map.Entry pair1, Map.Entry pair2) { 

            int valueCompare = - ( pair1.getValue().compareTo(pair2.getValue()) ); 
            int nameCompare = pair1.getKey().compareTo(pair2.getKey()); 

            if (valueCompare == 0) { 
                return ((nameCompare == 0) ? valueCompare : nameCompare); 
            } else { 
                return valueCompare; 
            } 
        } 
    } 


}

我试图按照其他论坛的建议降级到2.9.1版，但仍然无法正常工作

你能帮我吗？

谢谢

尝试使用npm run serve而不是npm run dev来运行vue.js

为什么尝试运行Vue.js无法正常工作？
