Error: Failed to lookup view "index" in views directory
Issue #8
resolved
Walking through the May 2015 article Riding ExpressJs and Node.js to the Web, I ran into this error. The file index.jade seems to be in the right place. \

When I used jade, I got the following error.

Please document the steps you are taking to run the program and the context. For example:
$ ssh aaron@ibmi $ cd path/to/app/dir $ ls -all $ ls -all node_modules $ node app.js -

here is the documentation. let me know if you need anything else

Could you also post the latest version of your

Hi Robert,
Earlier in this thread we discussed the
view engineline of code should not have a path in it. It should be the following:app.set('view engine', 'jade')Also, try using this line for the
viewslocation instead of the one you have:app.set('views', './views'); -

Hi Robert,
You left
__dirname +in theviewsline. Review my previous post.Also, I don't see the
expressmodule in thenode_modules/directory. Install it using this command:$ cd /home/iusr0042/node-js/nodejs_expressjs $ npm install expressIf you still have issues then I'd recommend removing Jade and re-installing it:
$ cd /home/iusr0042/node-js/nodejs_expressjs $ rm -rf node_modules/jade $ npm install jade -
reporter
I will attempt to reinstall as you have suggested. Thanks

I think the missing express module did the trick. Now all is working as expected. Thanks again.

Good deal! It's odd the program didn't bomb out sooner given the
require('express')should have failed. Not sure why that happened but will keep that in mind for others that might have similar issues.I will mark this as resolved.

One additional comment. I was able to complete the rest of the code without issue in the article. It provided a great base to see how I can use node.js on IBM i.

Excellent.
If you are looking for more thorough training you can also check out the training course I will be using at the 2016 Spring tradeshows (WMCPA, NEUGC). Right now it combines most of the articles I've written into a single document and it will eventually go further. Right now it is meant to fill a 2.5hr timeslot at a conference.

Hi Robert,
You have this for the
