npm start fails

[spaceone]

Hello tihawk,

I am unable to install/start this application:
First, a dependency was missing, I had to do:

$ npm install nodemon

After that, I run into troubles:

$ npmstart
> test_task@1.0.0 start /Downloads/register-user
> nodemon index.js

[nodemon] 1.19.1
[nodemon] to restart at any time, enter `rs`

    throw err;
    ^

$ nodejs --version

I also tried with an older version of nodejs, which causes:

# npm start

This issue seems to be related to the node version (I used ^10.). More precisely, it seems to be connected to node-pre-gyp : ref: node_sqlite3.node #906.

If using node v8.16.0 I suggest running npm rebuild. This worked for me:

$ npm rebuild

> sqlite3@4.1.0 install [...]/node_modules/sqlite3
> node-pre-gyp install --fallback-to-build

...

$ npm start

> test_task@1.0.0 start [...]/test-task
> nodemon index.js

[nodemon] 1.19.1

$ node --version

I also added 'use strict';, which should resolve the older node version problem.

Thank you, with another dependency and npm rebuild it works!

$ npm install node-pre-gyp
$ npm rebuild
