Heroku部署错误：找不到模块-编译 [英] Heroku deploy Error: Cannot find module - compilation

问题描述

这与其他问题类似，但我将解释有什么不同。

This is similar to other questions, but I'll explain what's different.

与其他许多问题一样，我有一个可以在自己的服务器上正常运行的应用，但是当我推送到Heroku时，出现以下错误：

Like the many others, I have an app that works fine on my own server, but when I push to Heroku, I get the following error:

remote:        > react-scripts build
remote:
remote: module.js:549
remote:     throw err;
remote:     ^
remote:
remote: Error: Cannot find module './error'
remote:     at Function.Module._resolveFilename (module.js:547:15)
remote:     at Function.Module._load (module.js:474:25)
remote:     at Module.require (module.js:596:17)
remote:     at require (internal/module.js:11:18)
remote:     at Object.<anonymous> (/tmp/build_96886a1c0acbba91a1be57ec9c1487e8/client/node_modules/browserslist/index.js:7:25)
remote:     at Module._compile (module.js:652:30)
remote:     at Object.Module._extensions..js (module.js:663:10)
remote:     at Module.load (module.js:565:32)
remote:     at tryModuleLoad (module.js:505:12)
remote:     at Function.Module._load (module.js:497:3)
remote: npm ERR! code ELIFECYCLE
remote: npm ERR! errno 1
remote: npm ERR! client@0.1.0 build: `react-scripts build`

区别是我没有 require（'./ error'）或安装的文件或文件夹或依赖项称为错误。

The difference, is I have no require('./error') or file or folder or dependency installed called error.

我尝试了以下操作：

1。

npm install -g

npm install -g

2。

删除node_modules

Delete node_modules

npm缓存清理--force

npm cache clean --force

npm install

npm install

3。
添加到我的package.json中：

3. Added to my package.json:

"engines": {
   "node": "8.11.3"
}

4。
从零开始，我克隆了我的工作应用程序，创建了一个新的Heroku实例，并尝试进行部署。

4. Three times from scratch I cloned my working app, created a new Heroku instance, and tried to deploy.

5。
试过这个：

5. Tried this:

heroku config：set NODE_MODULES_CACHE = false

heroku config:set NODE_MODULES_CACHE=false

这些解决方案和其他无效的方法来自这些帖子：

These solutions and others that didn't work came from these posts:

推荐答案

好吧，事实证明答案可以在Heroku的对Node.js部署进行故障排除页面。事实证明，我有时不小心开始跟踪node_modules。我不记得它是如何发生的，但是认为它是在我愚弄自己的.gitignore时发生的。直接从疑难解答页面获得的解决方案是：

Well, it turns out the answer can be found in Heroku's Troubleshooting Node.js Deploys page. It turned out that I had at some point accidentally started tracking node_modules. I can't remember how it happened, but think it happened at one point when I was fooling with my .gitignore. This solution, straight from the troubleshooting page was:

1. 检查以查看是否正在跟踪node_modules-如果返回的是列表结果，您是：

1. Check to see if you are tracking node_modules -- if this returns a list of results, you are:

git ls-files | grep node_modules

确保您不再跟踪它

Ensure you're not tracking it anymore

echo "node_modules" >.gitignore

删除缓存的node_modules

Remove the cached node_modules

git rm -r --cached node_modules

进行新提交

Make a new commit

git commit -am 'untracked node_modules'

这解决了我的问题。
