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.

Before posting the issue, I surfed on all possible websites to fix the issue with Node.js- npm cli I am encountering. None of the answers worked for me and I got stuck with. Can someone help to fix it?
The npm cli was running perfectly and it suddenly started to work giving me the traceback Please verify that the package.json has a valid 'main' entry. Even if I re-installed the node.js it has not resolved the issue. (see screenshot below)
The version node.js 16.17.1 on Windows 10

[Solved]:
Thanks everyone. The problem was lying in the directory C:\Users\your_comp_name\AppData\Local\node & C:\Users\your_comp_name\AppData\Roaming\npm that only needs to be removed to run npm cli further.
I have project and i have installed live-server using npm install --save-dev live-server
I want to now run live-server using scripts property in package.json file.
I know we can run it globally but i want to run live-server within the project folder.
i dont know why you want to do that, but you can add this on package.json
"scripts": {
"live": "live-server"
}
and then run with npm like this:
npm run live
here's an example of package.json:
{
"name": "tailwindcss",
"version": "1.0.0",
"description": "",
"main": "index.js",
"dependencies": {
"tailwindcss": "^1.4.6"
},
"devDependencies": {},
"scripts": {
"build:css": "tailwind build src/style.css -o style.css",
"live": "live-server"
},
"keywords": [],
"author": "",
"license": "ISC"
}
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
I am setting up my local module to be installed via npm install --save ../path/to/my/project.
When running the npm install, the node_modules/my_project directory gets populated with all source files - not just the dist/ folder as configured in package.json. I'm not sure why.
Here's my setup:
Test Project (main project)
Files:
index.js
package.json
dist/
index.js
package.json
{
"name": "test",
"version": "1.0.0",
"description": "a test",
"main": "dist/index.js",
"files": [
"dist"
],
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1"
},
"keywords": [
"test"
],
"author": "Me",
"license": "MIT"
}
-
Test Project2 (to import main project as a dependency)
package.json
{
"name": "test2",
"version": "1.0.0",
"description": "test2",
"main": "index.js",
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1"
},
"author": "Me",
"license": "MIT",
"dependencies": {
"test": "file:../test"
}
}
Once I run npm install, my node_modules/ directory looks like this:
test/
index.js
package.json
dist/
index.js
Is there something I'm overlooking? I'm under the assumption that the files: [] field is used to specify which files are included when the package is installed.
Additionally, I've tried running npm cache clean -f and npm cache verify, neither of which solve my issue.
It seems that this only occurs when attempting to install a local module. To test, I made a test repo on github and installed from there, only the dist/ file was included. Not sure why.
I have a package.json file like this
{
"name": "E2E",
"version": "1.0.0",
"description": "AngularJS E2E testing",
"main": "conf.js",
"scripts": {
"postinstall": "node_modules/protractor/bin/webdriver-manager update",
"test": "echo \"Error: no test specified\" && exit 1"
},
"license": "ISC",
"devDependencies": {
"protractor": "^2.2.0"
}
}
when running command npm install after protractor is installed its throwing error
node_modules/protractor/bin/webdriver-manager update
'node_modules' is not recognized as an internal or external command, operable program or batch file
Ok found the fix, I need to run it as node command like this
"postinstall": "node node_modules/protractor/bin/webdriver-manager update",
Try prepending the path to executable with a dot followed by a slash:
./node_modules/protractor/bin/webdriver-manager update
The problem is that you need to be in the folder where that command is installed before you call it. Assuming you are using Windows, this can be solved by running a simple batch file:
#echo off
call npm install -g protractor
call npm install
cd C:/Users/%USERNAME%/AppData/Roaming/npm/node_modules/protractor/selenium/
call webdriver-manage update
You should be able to run a batch file from anywhere. In fact, the entire Protractor testing process can be automated with a batch file. You just need to add Grunt, load-grunt-tasks, grunt-protractor-runner, jasime, and protractor-jasmine2-html-reporter to your package.json:
{
"name": "yourproject",
"version": "0.0.1",
"dependencies": { },
"devDependencies": {
"grunt": "~0.4.1",
"load-grunt-tasks": "~1.0.0",
"grunt-protractor-runner": "~2.1.0",
"jasmine": "~2.3",
"protractor-jasmine2-html-reporter": "~0.0.5"
},
"engines": {
"node": ">=0.12.0"
}
}
After you configure Protractor and writing some tests, you can then call the whole process with one simple batch file:
#echo off
cd %CD%
#echo running tests
call grunt
#echo Opening test results in browser
start "" %CD%\tests\reports\index.html
