Updating to 2.13.0 breaks the build

[rprimet]

Is this a bug report?

Yes

Environment

2. node -v: 8.9.4
3. npm -v: 3.10.8

Then, specify:

1. Operating system: Linux
2. Browser and version (if relevant): Irrelevant

Steps to Reproduce

1. set the react-script-ts version of an existing project to0.2.13
2. run npm install
3. run npm start

Expected Behavior

The project installs updated dependencies, then builds and starts

Actual Behavior

• During the npm install phase:

├─┬ react-scripts-ts@2.13.0 
│ ├─┬ tsconfig-paths-webpack-plugin@2.0.0 
│ │ ├─┬ chalk@2.3.0 
│ │ │ └── supports-color@4.5.0 
│ │ └─┬ tsconfig-paths@3.1.1 
│ │   ├── deepmerge@2.0.1 
│ │   └── strip-bom@3.0.0 
│ └── UNMET PEER DEPENDENCY typescript@^2.1.0
└── UNMET PEER DEPENDENCY typescript@2.x

During the npm start phase:

> react-scripts-ts start

module.js:540
    throw err;
    ^

Error: Cannot find module 'typescript'
    at Function.Module._resolveFilename (module.js:538:15)
    at Function.Module._load (module.js:468:25)
    at Module.require (module.js:587:17)
    at require (internal/module.js:11:18)

OK, so this has been reported in #241

Leaving this issue open since it is not obvious how to migrate without documentation

Oh... yes, this only happens when updating from < 2.13.0 to 2.13.0 - typescript was moved to be a peer dependency of react-scripts-ts, which installs typescript as a dev dependency when initializing a new project. I'll see if I can get some instructions pushed tomorrow.

Until then:
#165 (comment)
