节点无法在Express / React应用中查找视图“错误”

Question

我正在使用我的应用程序，并且它在几个小时前就可以运行了。但是现在，当我启动它时，出现以下错误。

/views中没有/lib目录，但是我的src/中有。它包含error.jade.

我已经尝试了一切。删除/lib，然后重新安装所有内容...

  

错误：无法在视图目录中查找视图“错误”   “ /用户/ vemundeldegard /所有/服务器/ lib /视图”           在Function.render（/Users/vemundeldegard/all/server/node_modules/express/lib/application.js:580:17）           在ServerResponse.render（/Users/vemundeldegard/all/server/node_modules/express/lib/response.js:1008:7）           在/Users/vemundeldegard/all/server/lib/app.js:47:7           在Layer.handle_error（/Users/vemundeldegard/all/server/node_modules/express/lib/router/layer.js:71:5）           在trim_prefix（/Users/vemundeldegard/all/server/node_modules/express/lib/router/index.js:315:13）           在/Users/vemundeldegard/all/server/node_modules/express/lib/router/index.js:284:7           在Function.process_params（/Users/vemundeldegard/all/server/node_modules/express/lib/router/index.js:335:12）           在下一个（/Users/vemundeldegard/all/server/node_modules/express/lib/router/index.js:275:10）           在Layer.handle_error（/Users/vemundeldegard/all/server/node_modules/express/lib/router/layer.js:67:12）           在trim_prefix（/Users/vemundeldegard/all/server/node_modules/express/lib/router/index.js:315:13）

App.js

var createError = require('http-errors');
var express = require('express');
var path = require('path');
var cookieParser = require('cookie-parser');
var logger = require('morgan');
var { BUILD_DIR, PUBLIC_DIR } = require('./paths');
var reactRenderer = require('./react-renderer');

var indexRouter = require('./routes/index');
var usersRouter = require('./routes/users');

var app = express();

// view engine setup
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'jade');

app.use(logger('dev'));
app.use(express.json());
app.use(express.urlencoded({ extended: false }));
app.use(cookieParser());

app.get('/', reactRenderer);

app.use(express.static(BUILD_DIR));
app.use(express.static(PUBLIC_DIR));

// catch 404 and forward to error handler
app.use(function(req, res, next) {
  next(createError(404));
});

// error handler
app.use(function(err, req, res, next) {
  // set locals, only providing error in development
  res.locals.message = err.message;
  res.locals.error = req.app.get('env') === 'development' ? err : {};

  // render the error page
  res.status(err.status || 500);
  res.render('error');
});

module.exports = app;

Paths.js：

"use strict";

var path = require('path');

var BUILD_DIR = path.join(__dirname, '..', '..', 'client', 'build');
var PUBLIC_DIR = path.join(__dirname, '..', '..', 'public');
module.exports = {
  BUILD_DIR: BUILD_DIR,
  PUBLIC_DIR: PUBLIC_DIR
};

（我想发表评论，但是我没有足够的代表）

__dirname的使用引起了我的注意-您是否可能无意中从错误的目录（在这种情况下为lib）运行应用程序？
