I created a simple new schematic using the angular schematics cli. This schematic takes as input a name, and generates a file in the tree. My `files/` directory looks like:

```
src/
  app/
    __name@dasherize__.ts

```

I've built it, and then created a new angular project:

```
ng new test-app --routing --style css

```

I then cd into the test-app directory and link to my sample schematic:

```
npm link ../schematics/sample-schematic

```

I then run my schematic:

```
ng g sample-schematic:sample

```

however I get the following error when I do so:

```
Pipe "dasherize" is not defined. 

```

If I change the file name in my `files` directory to `test.ts` it works fine, and the file is created. I am guessing i am missing some import to use the various schematic functions in my test-app project. My dependancies and dev-dependancies for `test-app` looks like:

```
