Error when running rxjs-5-to-6-migrate

See original GitHub issue

Installed rxjs-tslint globally, attempting to upgrade my Angular application from version 5 to 6.

I’m using the command

rxjs-5-to-6-migrate -p src/tsconfig.app.json

But it results in this error

Running the automatic migrations. Please, be patient and wait until the execution completes.
child_process.js:644
    throw err;
    ^

Error: Command failed: /usr/lib/node_modules/rxjs-tslint/node_modules/.bin/tslint -c /usr/lib/node_modules/rxjs-tslint/rxjs-5-to-6-migrate.json -p src/tsconfig.app.json --fix

There are no spaces in the path to any of the files. I have tried specifying the full path to tsconfig.app.json, same result.

If you run an npm install from inside the rxjs-tslint package’s directory, it’ll make sure it has tslint available. No need to be gross and install something globally.

cd node_modules/rxjs-tslint
npm install
cd ../..
./node_modules/.bin/rxjs-5-to-6-migrate -p src/tsconfig.app.json

For bonus points, use npx to access the binary (I found out recently it ships with npm): npx rxjs-5-to-6-migrate -p src/tsconfig.app.json

In Angular Update Guide | 5.2 -> 6.0 for Advanced Apps checklist step Choose a value of off for preserveWhitespaces in your tsconfig.json to gain the benefits of this setting while the default is still to preserve whitespace. causes the problem.

Running rxjs-5-to-6-migrate -p ./src/tsconfig.app.json (no matter global or local installed) an error occurred:

./node_modules/.bin/rxjs-5-to-6-migrate -p ./src/tsconfig.app.json

so removing preserveWhitespaces solved the problem for me
