Feathers: error TS2468: Cannot find global value 'Promise'

[peterennis]

Steps to reproduce

Follow directions for feathers-basic on Windows 10 from here: https://docs.feathersjs.com/guides/basics/starting.html#installing-feathers

• [x] Tell us what broke. The more detailed the better.

Lots of breakage. Maybe the instructions are written using a Mac?

C:\ae\adaept.com\aefea>ts-node app.ts
'ts-node' is not recognized as an internal or external command,
operable program or batch file.

Setup using nodemon then this:

C:\ae\adaept.com\aefea>npm start

> [email protected] start C:\ae\adaept.com\aefea
> nodemon src/index.ts

'nodemon' is not recognized as an internal or external command,
operable program or batch file.
npm ERR! code ELIFECYCLE
npm ERR! errno 1
npm ERR! [email protected] start: `nodemon src/index.ts`
npm ERR! Exit status 1
npm ERR!
npm ERR! Failed at the [email protected] start script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

npm ERR! A complete log of this run can be found in:
npm ERR!     C:\Users\peter\AppData\Roaming\npm-cache\_logs\2019-12-21T04_13_25_726Z-debug.log

Configure start and get this:

C:\ae\adaept.com\aefea>npm start

> [email protected] start C:\ae\adaept.com\aefea
> nodemon src/index.ts

[nodemon] 2.0.2
[nodemon] to restart at any time, enter `rs`
[nodemon] watching dir(s): src\**\*.ts
[nodemon] watching extensions: js,mjs,json
[nodemon] starting `node src/index.ts index.js`
internal/modules/cjs/loader.js:797
    throw err;
    ^

Error: Cannot find module 'C:\ae\adaept.com\aefea\index.js'

}
[nodemon] app crashed - waiting for file changes before starting...
Terminate batch job (Y/N)?

So it is not really a quick start so far.

• [x] If you can, please create a simple example that reproduces the issue and link to a gist, jsbin, repo, etc. This makes it much easier for us to debug and issues that have a reproducable example will get higher priority.

The instructions have been confirmed to work on Windows. If you are already getting an error for ts-node not being available, it is probably an issue with your NodeJS setup. Normally it is related to permissions.

@daffl
I got it started with Windows but then the error is Cannot find global value 'Promise'
Looks like it is trying to run the code.
Repo: https://github.com/peterennis/aefea/commits/master

Is there a requirement for global install of some packages?

[daffl]

I have a feeling you may not have run the TypeScript tab version of the initialization commands in the Quick start guide. With:

# Install TypeScript and its NodeJS wrapper globally
npm i typescript ts-node -g

npm init --yes
# Also initialize a TS configuration file that uses modern JavaScript
tsc --init --target es2018

Everything will work as expected (the tsc --init --target es2018 is the secret here).

@daffl

tsc --init --target es2018 was the fix
