我正在做一个小型节点项目，我需要安装 express 验证器，但它没有安装。我的根文件有 app.js，我在其中导入所有 deps 和一个 package.json 文件，除了 index.ejs 文件。我的 app.js 看起来像这样：
应用程序.js：
var express = require("express");
var bodyParser = require("body-parser");
var path = require("path");
var app= express();
var expressValidator = require("express-validator");
app.use(expressValidator());
app.post('/', function(req, res) {
req.assert(req.body.password,'Enter Password').notEmpty();
})
var errors = req.validationErrors();
//view engine
app.set('view engine','ejs');
app.set('views',path.join(__dirname,'views'));
//body-parser:
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({extended: false}));
//app.use(express.static(path.join(__dirname, "public")))
var people=[
{firstname: "Jeff", lastname: "Murphy", age: 30},
{firstname: "Thomas", lastname: "Reynolds", age: 21},
{firstname: "Dan", lastname: "Schneider", age: 22}
]
app.get('/',function(req,res){
res.render("index",{
title: "Customers",
people: people
});
app.post("/users/add", function(req,res){
console.log("form submitted");
var forminfo = {
firstname: req.body.firstname,
lastname: req.body.lastname
}
console.log("forminfo: ",forminfo)
})
//for parsing arrays use res.json:
//res.json(people[1].name)
});
app.listen(3000, function(){
console.log("server set up at port 3000")
})
包.json：

根据调试日志，我在代理上。但我删除了代理，然后又出现了。请指导我出了什么问题。
