我正在使用React制作一个应用程序，并在之后将其部署到Heroku。在本地主机上一切都很顺利，没有任何错误，webpack也没有编译错误。我已经在Heroku上设置了环境变量。
然而，当我将其部署到Heroku时，我得到一个空白屏幕和控制台中的以下错误（我已经正确地引入了TodoApi并尝试了各种方式 - import等，在本地主机上没有问题）：
我已经尝试了几天来解决这个问题，所以非常感谢任何帮助。
Uncaught Error: Cannot find module "TodoApi"

这是我的webpack和package.json文件：
var webpack = require('webpack');
var path = require('path');
var envFile = require('node-env-file');
process.env.NODE_ENV = process.env.NODE_ENV || 'development';
try {
envFile(path.join(__dirname, 'config/' + process.env.NODE_ENV + '.env'));
} catch(e) {
