I already installed it using npm install and I tried reinstalling but that didn't work any ideas?

Solution 1

try installing mongoose using this command:

npm install mongoose

do not use the -g switch.

BTW: I ran command prompt in admin mode. Reference

Solution 2

You can do either of two things to make it run :-

1) Install mongoose globally with below steps :-

a)npm install mongoose -g

b) Go to your app directory, where bot.js is located and then run

npm link mongoose

Explanation :- When you install a package globally via npm, it is downloaded to global node_module folder. For me(Mac user), it's under /usr/local/lib/node_modules/mongoose. We link this to that directory from where you are trying to run module.js.

2) Another approach is to install mongoose locally, not globally via

npm install mongoose

After following either of these, you will be seeing node_modules --> mongoose folder under the 'bot.js' directory, which means mongoose has been successfully installed.

Now, run node bot.js , it will work .

Solution 3

Install with the --save option:

npm install mongoose --save

This adds mongoose it to package.json which Heroku uses to build your app.

Solution 4

You have to call in the command line

npm install mongoose

remember to call this command from the root path of your project

Solution 5

npm install mongoose

it will work and if everything is alright then you will get following in your terminal
