npm bugs treehouse-express-auth. I can't get the app to run on the localhost:3000 server.

Cynthia,

Hi there! Based upon the error message that you shared, it sounds like you're attempting to load the mongoose module but you don't have it installed yet. Did you run the command npm install mongoose before attempting to load the module using require('mongoose')?

Thanks ~James

Here is my GitHub link to the app.js file: https://github.com/rockandrollbaby/treehouse.

I added the package.json file: https://github.com/rockandrollbaby/treehouse.

I did the npm install. I ran the nodemon command. The server still won't run. Here are my error messages:

It looks like there is a deprecating warning error message: (node:2605) DeprecationWarning: open() is deprecated in mongoose >= 4.11.0, use openUri() instead, or set the useMongoClient option if using connect() or createConnection(). See http://mongoosejs.com/docs/4.x/docs/connections.html#use-mongo-client

I do have those, but my GitHub account didn't let me upload that many folders and files. I will try the app to see if it runs on the server.

Thank you.

It is working! Thank you, James for all of your help!

Hi James,

I am on the Rest API app, and am getting this error message in the terminal:Error: Cannot find module './routes' at Function.Module._resolveFilename (module.js:469:15) at Function.Module._load (module.js:417:25) at Module.require (module.js:497:17) at require (internal/module.js:20:19) at Object.<anonymous> (/Users/Cynthia/Documents/treehouse/rest_api_app/app.js:5:14) at Module._compile (module.js:570:32) at Object.Module._extensions..js (module.js:579:10) at Module.load (module.js:487:32) at tryModuleLoad (module.js:446:12) at Function.Module._load (module.js:438:3) setups-MacBook-Pro:rest_api_app Cynthia$

I did as you said. Does this mean the server is working? ^Csetups-MacBook-Pro:node_authentication_app Cynthia$ nodemon [nodemon] 1.18.9 [nodemon] to restart at any time, enter rs [nodemon] watching: .
