【问题描述】：
我的 heroku 应用程序出现错误 2019-08-03T10:56:56.753066+00:00 app[web.1]: Error: Cannot find module './models/Marker' . 我已经在上面看到了topic，但它对我不起作用（删除 node_modules 包不起作用/将 node_modules 添加到 .gitignore）
我的 package.json ：
{
"name": "node_passport_login",
"version": "2.0.0",
"description": "Node.js authentication with Passport",
"main": "app.js",
"scripts": {
"start": "node app.js",

},

}
需要模型的行：
const Marker = require('./models/Marker');
整个错误：

编辑：./models/Marker 是猫鼬模式的模块导出目录
【问题讨论】：
-
什么是
./models/Marker？ -
@NinoFiliu 这是猫鼬模式的模块导出目录
-
“删除 node_modules 包不起作用/将 node_modules 添加到 .gitignore”—如果已跟踪，您应该绝对从存储库中删除
node_modules/。你不能只添加到.gitignore；它必须被删除，例如使用git rm -r --cached node_modules之类的东西，然后再次提交和部署。 -
@Chris 我做了
git rm -r --cached node_modules但它打印了fatal: pathspec 'node_modules' did not match any files
