节点无法在Express/react应用程序中查找视图“错误”

Question

我正在开发我的应用程序，它在几个小时前工作。但是现在当我启动它时，我得到以下错误。

在/lib中没有/views目录，但在mysrc/中有。它包含错误。杰德

我什么都试过了。删除/lib，重新安装所有内容...

错误：无法在函数处的视图目录“/Users/vemundeldegard/all/server/lib/views”中查找视图“Error”。在ServerResponse上呈现（/Users/vemundeldegard/all/server/node_modules/express/lib/application.js:580:17）。render（/Users/vemundeldegard/all/server/node_modules/express/lib/response.js:1008:7）位于/Users/vemundeldegard/all/server/lib/app。第二层的js:47:7。在/Users/vemundeldegard/all/server/node_modules/express/lib/router/layer.js:71:5）的trim_前缀（/Users/vemundeldegard/all/server/node_modules/express/lib/router/index.js:315:13）处处理_错误。js:284:7 at函数。在下一层（/Users/vemundeldegard/all/server/node_modules/express/lib/router/index.js:335:12）处理_参数（/Users/vemundeldegard/all/server/node_modules/express/lib/router/index.js:275:10）。在trim_前缀处处理_错误（/Users/vemundeldegard/all/server/node_modules/express/lib/router/layer.js:67:12）（/Users/vemundeldegard/all/server/node_modules/express/lib/router/index.js:315:13）

应用程序。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;

路径。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
};

（我愿意发表评论，但我没有足够的代表）

__dirname的用法引起了我的注意--有没有可能您无意中从一个不正确的目录（在本例中为lib）运行您的应用程序？
