I have the following compilation error using Travis CI for my github project:

sh: 1: mocha: not found

My main project folder, "projectRoot", which corresponds to my github repo, contains the .travis.yml configuration file; it also contains several sub folders (one per application):

projectRoot

|-- app1

    |-- app1.js

    |-- package.json

    |--- node_modules

         |--- .bin

              |--- mocha

              |--- mocha.cmd

|-- app2

    |-- app2.js

    |-- package.json

    |--- node_modules

         |--- .bin

              |--- mocha

              |--- mocha.cmd

|-- app3

|-- ...

Each application has its own package.json and node_modules packages.

The package.json of app1 contains the following:

  "scripts": {

    "test": "mocha"

  },

  "devDependencies": {

    "chai": "^4.2.0",

    "mocha": "^5.2.0"

  },

And I get the following error when Travis CI tries to run the unit tests of app1:

$ npm test

> projectRoot@1.0.2 test /home/travis/build/username/projectRoot/app1

> mocha

sh: 1: mocha: not found

npm ERR! Test failed.  See above for more details.

I tried adding the following before_script to change the current directory to app1, then amending the PATH variable prior to starting the tests:

before_script:

  - echo "*** PRE BUILD SCRIPT ***"

  - cd ./app1

  - export PATH=$(pwd)/node_modules/.bin:$PATH

  - echo $PATH

  - echo "*************************"

After doing so, the "echo $PATH" line above shows in the travis logs that PATH contains the project folder:

$ echo $PATH

/home/travis/build/username/projectRoot/app1/node_modules/.bin:/home/travis/.rvm/gems/ruby-2.4.1/bin:/home/travis/......

But the error remains.

I also tried:

PATH=./node_modules/.bin:$PATH.

or changing the test script to use a relative path:

"scripts": {

    "test": "./node_modules/.bin/mocha"

 }

But the same error remains.

Any advise would be truly appreciated.

Many thanks for your help
