Following instructions from the RC0 release notes I created a new project to migrate my beta-11 project to RC0. I checked that I the new CLI was installed and after all the steps and running ionic build android I got an error saying it could not find tslint nor ngc:
[16:36:28] ionic-app-scripts 0.0.27
[16:36:28] build prod started ...
[16:36:28] clean started ...
[16:36:28] clean finished in 6 ms
[16:36:28] copy started ...
[16:36:28] ngc started ...
[16:36:29] lint started ...
[16:36:29] Unable to find "tslint" command: null
[16:36:29] copy finished in 35 ms
[16:36:29] Unable to find Angular Compiler "ngc" command: null
It still didn't work even after installing them globally, only when running npm install tslint && npm install ngc it started working. Still I am running into an error that I haven't figured out yet:
tslint: /Users/abhaya/projects/myApp/node_modules/tslint/lib/configuration.js:184
throw new Error("Could not find custom rule directory: " + directory);
^

It all started working when I re-created the project after upgrading node to v6 (and as a result upgrading npm to v3). I think it would be worth noting this requirement in the release notes.
Thanks!
I have the same issue, brand new install, new project, but the same error. Just updated npm to 3.10.8 too
I stand corrected, I too needed Node v6 for it to work. Agree, it should be mentioned in the release notes
I have [email protected] and node v6.6.0 and still getting the tslint error

I am getting the same error when trying to build
