node.js - CentOS， Node 找不到模块

Question

我在我的 MacOS 上很好地运行了 index.js。
今天使用git&&Github将node项目部署到CentOS 7。
该项目向我显示了错误。node index.js我看到一个错误 Cannot find module 'Joi'npm list --depth=0

npm list --depth=0
nodeMongoVdily@1.0.0 /root/newNode
├── express@4.16.4
├── joi@14.3.1
└── mongoose@5.4.17

谁知道原因？

我在 Google 和 Stack Overflow 上搜索了半个小时。我没有发现任何东西可以解决这个错误。

Answer 1

在 https://discuss.circleci.com/t/error-uncaughtexception-cannot-find-module-joi/24949/2

我找到了答案。

You wouldn’t believe but I change my code from
let Joi = require('Joi')
to
let joi = require('joi')
all small-case, surprisingly it fixed the build.
But I am guessing y it worked locally :thinking:
