sh: 1: cucumber.js: not found - node.js

Trying to use this tutorial here:
https://github.com/lykmapipo/nodejs-cucumber-sample
The output to nvm current is: v10.12.0.
The output to npm --version is: 6.4.1>
I get the error below once I invoke npm test:
> nodejs-cucumber-sample#0.0.1 test /home/gnuc/code/nodejs-cucumber-sample
> cucumber.js
sh: 1: cucumber.js: not found
I am not sure as to why this is the case. The $PATH includes /home/gnuc/.nvm/versions/node/v10.12.0/bin. And I have already used npm install cucumber -g and npm install cucumber

Make sure that your package.json file includes this: "test": "cucumber-js"
So that it looks something like this:
{
"name": "hellocucumber",
"version": "1.0.0",
"description": "",
"main": "index.js",
"scripts": {
"test": **"cucumber-js"**
},
"keywords": [],
"author": "",
"license": "ISC",
"devDependencies": {
"cucumber": "^5.1.0"
}
}

So, you need to actually call the npm package/library. I have the following defined in my package.json:
"scripts": {
"test": "node ./node_modules/.bin/cucumber-js"
},
you can also add some ---tags in this call.
"scripts": {
"test": "node ./node_modules/.bin/cucumber-js --tags #RegressionTestSuite"
},
this will run any feature files that have #RegressionTestSuite at the top
Also, I have an output/results file created with a time stamp.
"scripts": {
"test": "node ./node_modules/.bin/cucumber-js --tags #RegressionTestSuite --format json:./results/log_new_`date +%Y-%m-%m__%H-%M`.json""
},
I hope this helped.

node ./node_modules/cucumber/bin/cucumber-js
This command is working fine.
And you got sh:1: cucumber.js: not found error means first things please look out the path of cucumber.js

How can I execute a bin with yarn?

I have the following package.json and I'd like to run the bins "build" and "run":
{
"name": "simple-site",
"version": "0.0.5",
"license": "MIT",
"bin": {
"build": "./bin/build.js",
"dev": "./bin/dev.js"
}
}
I've tried:
yarn run build
and I get
error Command "build" not found.
I've also tried:
yarn build
but the same thing happens:
error Command "build" not found.
It's propably not the right way to run bins. But then again, what is the right way to run bins with yarn?
Your package isn't installed.
When Yarn (and NPM) installs your package, it adds the commands under node_modules/.bin/, e.g. node_modules/.bin/build. Running yarn build would (if it doesn't find a matching script in the current package) look for a build in this .bin, then traverse upwards through the filesystem, looking for other node_modules/.bin/build's.
If your build script is only meant to be run while developing that specific package, add it as a script (see example here). It would more or less look like this:
{
"name": "simple-site",
"version": "0.0.5",
"license": "MIT",
"scripts": {
"build": "node ./bin/build.js",
"dev": "node ./bin/dev.js"
}
}
Do not need relative path added:
{
"name": "simple-site",
"version": "0.0.5",
"license": "MIT",
"scripts": {
"build": "build.js",
"dev": "dev.js"
}
}
The hashbang comment specifies the path to a specific JavaScript interpreter that you want to use to execute the script.
For example, helloWorld.js in ./node_modules/.bin:
#!/usr/bin/env node
console.log("Hello world");
You have a typo in your package.json. Where it says bin: it should say scripts:
{
"name": "simple-site",
"version": "0.0.5",
"license": "MIT",
"scripts": { // <-- here
"build": "./bin/build.js",
"dev": "./bin/dev.js"
}
}

Call script from custom npm package

I want to write my own npm package to analyse the structure of a vue project (vueanalyser). So I created a new package with npm init --scope=#my-username and set the "main" property to index.js.
// package.json of the custom package
{
"name": "#my-username/vueanalyser",
"version": "1.0.0",
"main": "index.js",
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1"
},
"author": "",
"license": "ISC",
"repository": {
"type": "git",
"url": "..."
},
"bugs": {
"url": "..."
},
"homepage": "...",
"description": ""
}
I published the package and added it to my vue project (.node_modules/#my-username/vueanalyser). Now I want to add a command like "analyse": "vueanalyser start" to the script property of the package.json of the vue project. If I do so I obviously get an error, that the command is unknown.
So I realized, that I can call the index.js with "analyse": "node node_modules/#my-username/vueanalyser/index.js, but I have seen packages where scripts can be called with a much shorter way e.g. "styleguide:build": "vue-styleguidist build". What do I have to change in order to call my script this way ("analyse": "vueanalyser start")?
the npm bin property
This specifies executables to copy into node_modules/.bin.
Add the executable header to your index.js
Add this to the first line: #!/usr/bin/env bash
Make the file executable
chmod +x index.js
Edit package.json
Add the bin property:
{
...
"bin": { "vueanalyser": "index.js" }
Republish package
Install package
Find node_modules/.bin/vueanalyser is a symlink to ../<package_name>/index.js!

Heroku: Bunch of npm errors on deployment

I have a bunch of npm errors in my heroku logs. How can I begin to debug this? thanks!

package.json
{
"name": "server",

"main": "index.js",
"engines": {
"node": "8.1.1",
"npm": "5.0.3"

NPM ERR: missing script: start
It seems like you're missing the "start" script in your package.json file. That's where I would start looking. Heroku might assume you've set this script up beforehand. Here's a sample package.json file with the start script:
{
"name": "your-app",
"version": "1.0.0",
"main": "index.js",
"scripts": { // your npm scripts go here
"start": "nodemon index.js", // or whatever server package you're using
"lint:js": "node_modules/eslint/bin/eslint.js ./ ./**/*.js --fix; exit 0",
"lint:css": "node_modules/csslint/cli.js public/css/; exit 0",
"test": "NODE_ENV=test node_modules/mocha/bin/mocha"
},
"more": "settings below"
}
Here's a blurb from the Heroku website:
Specifying a start script
To determine how to start your app, Heroku first looks for a Procfile. If no Procfile exists for a Node.js app, we will attempt to start a default web process via the start script in your package.json.
The command in a web process type must bind to the port number specified in the PORT environment variable. If it does not, the dyno will not start.

Why devDependencies is not installed

I developed a package for example: testlab, and its package.json is:
{
"devDependencies": {
"mocha": "^2.0.0"
},
"name": "#aab/testlab",
"version": "2.6.0",
"description": "example for npm",
"main": ".\\dest\\main.js",
"dependencies": {
"gulp": "^3.9.1",
"gulp-changed": "^1.3.2"
},
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1"
},
"keywords": [
"test"
],
"author": "aab <aab#exmaple.com>",
"license": "ISC"
}
Say I included mocha in devDendencies, and then I created a local directory called e.g. c:\example and used
npm install #aab/testlab --only=dev
to get my package under c:\example, but when I looked at c:\example\node_modules, I did not find mocha package is installed. I also tried other command like
npm install #aab/testlab
still no luck. I used NodeJS v4.6.0 and npm 4.0.2. Although nodeJS seems a little old, could any one help me that?
I have seen this happen only when NODE_ENV is set to PRODUCTION. Something else might be setting it.

Watcher automation in Mocha

I would like to achieve automation of motcha --watcher feature using package.json file without globally installing mocha.
One of npm features is to allow add custom scripts into npm command. Previously I configured test runner successfully and I can type in bash now:
npm test
Everything works fine, so I would like also do something similar because
./node_modules/mocha/bin/mocha --watch app.js test.js"
is not too efective.
My goal is to run mocha watcher by typing in bash:
npm watch
Unfortunately watcher doesn't run - instead I see standard output of npm command without parameters. It looks like my custom script wasn't registered by npm.
Here is my actual package.json file
{
"name": "screencast",
"version": "1.0.0",
"description": "",
"main": "index.js",
"scripts": {
"test": "mocha test.js", // works properly after typing 'npm test'
"watch": "mocha --watch app.js test.js" // Syntax looks ok, but command 'npm watch' d
},
"author": "",
"license": "ISC",
"dependencies": {
"express": "^4.10.6"
},
"devDependencies": {
"mocha": "^2.0.1",
"supertest": "^0.15.0"
}
}
Anyone had this issue before?
For a 'custom' script like watch, you have to do npm run watch instead of npm watch
