@mgechev any idea? This seems to occur in the codelyzer code itself.

[mgechev]

Yes, most likely the configuration is not valid. The current master contains valid configuration. You can fix it manually, by updating tslint.json or the fix will come with the next release automatically.

[mgechev]

@hansl I think we can close this issue.

[neo]

right

I know this is closed, but it might help someone :)

I got here looking for the this.nameValidator is not a function codelyzer error. It turned out to be because I was not specifying the selectorPrefix in the component|directive-selector rule in tslint.json.

before

"directive-selector": [true, "attribute", "camelCase"]

after (and working)

"directive-selector": [true, "attribute", "", "camelCase"]
