npm run build fails with create-react-app

Question

I have a node/express/react application I am building using create-react-app for the client side. Whenever I run npm run build I get this error:

> [email protected] build /Users/crescentfresh/myApp/client
> react-scripts build

module.js:487
    throw err;
    ^

Error: Cannot find module 'dotenv-expand'

This is my package.json for my create-react-app directory:

{
  "name": "frontend",
  "version": "0.1.0",
  "private": true,
  "proxy": {
    "/api/*": {
      "target": "http://localhost:3000"
    }
  },
  "dependencies": {
    "@uppy/core": "^0.27.3",
    "@uppy/dashboard": "^0.27.5",
    "@uppy/react": "^0.27.5",
    "@uppy/tus": "^0.27.5",
    "apollo-cache-inmemory": "^1.2.5",
    "apollo-client": "^2.3.5",
    "apollo-link": "^1.2.2",
    "apollo-link-error": "^1.1.0",
    "apollo-link-http": "^1.5.4",
    "apollo-link-state": "^0.4.1",
    "axios": "^0.18.0",
    "bootstrap": "^4.1.1",
    "graphql": "^0.13.2",
    "graphql-tag": "^2.9.2",
    "prop-types": "^15.6.2",
    "react": "^16.4.1",
    "react-apollo": "^2.1.9",
    "react-dom": "^16.4.1",
    "react-router": "^4.3.1",
    "react-router-dom": "^4.3.1",
    "react-scripts": "2.0.3",
    "react-spinners": "^0.4.5",
    "reactstrap": "^6.2.0",
    "recompose": "^0.29.0"
  },
  "scripts": {
    "start": "cross-env PORT=3003 react-scripts start",
    "build": "react-scripts build",
    "test": "react-scripts test --env=jsdom",
    "eject": "react-scripts eject"
  },
  "devDependencies": {
    "cross-env": "^5.2.0"
  }
}

This used to build but recently began failing. I tried removing the packages that were added sometime before the failed builds happened but that didn't help (uppy and axios packages) so I am not sure if that's even related.

If there's anything else I should include please let me know.

it is most likely because of Node.js version. try to use stable version of node and you also can use nvm in order to switch between different versions — Sajed

Have you tried installing the missing module 'dotenv-expand'? — ngearing

@crescentfresh 8.1.1 is stable, have you tried to reinstall create-react-app ? — Sajed

There are many problems that may lead to this problems i.e,React,npm,the package source.Maybe run this in terminal npm i --save-dev dotenv-expand / yarn add --save-dev dotenv-expand

Thanks for the response. This resolved the error but left me with a new one. I'm thinking something is corrupted and I should just clone my repo again and start over. My friend isn't getting the same error on his machine so I have to assume I have something screwy in my local environment.
