Cannot find module "loopback"

I receive the following error when I run the command slc run

tinker@tinker:~/Desktop/loopback$ slc run

I get the above error only for slc run. All the other slc commands works just fine.

I had installed loopback with npm install -g strongloop

To use slc run without an argument, your working directory must be the root directory of your LoopBack app (containing the main script).  See the slc run command reference doc.  In this case your working directory is loopback, so its looking for an application with that name.  First, create an app with slc loopback, then cd to that directory and run it, as explained in Getting started with LoopBack.

And in general, instead of using slc run, you should either just run your app with node . or use slc start, as explained here: http://docs.strongloop.com/display/SLC/Running+apps+with+slc

Please make sure there is no error during `npm install -g strongloop`.

Thanks,

I am using MySQL as the datasource and I have a MySQL db setup already on my localhost. When I try to run node . I get the following error. I did install the MySQL connector but it seems not to be working. I installed the connector by running npm install loopback-connector-mysql --save from the project directory. Still no luck.

WARNING: LoopBack connector "mysql" is not installed as any of the following modules:

 ./connectors/mysql
loopback-connector-mysql

To fix, run:

    npm install loopback-connector-mysql

      throw er; // Unhandled 'error' event
