Preparation:

  1. install ember npm install ember-cli
  2. start a new project: ember new ember-demo

Now, lets try to remove any plugin (I have tried to remove ember-cli-jshint and ember-welcome-page) and we will get broken ember project, any call to ember utility will cause an error:

Error: Cannot find module 'ember-try-config'
at Function.Module._resolveFilename (module.js:339:15)
at Function.Module._load (module.js:290:25)

Here is my environment:

host@user $ ember --version  --verbose

PREVIOUS PROBLEM

Previously, I wanted to use eslint instead of jshint in ember app. I just followed instructions from ember-cli-eslint github page, and run this two commands:

npm uninstall --save-dev ember-cli-jshint
ember install ember-cli-eslint

After this my project have turned into a pumpkin: no one ember command doesn't work, throwing an error (see above)

If you will skip the uninstall step - you won't get a pumpkin)) in this case ember continues to work as expected, but eslint won't be a default project's linting tool.

DOES ANYBODY KNOW, how to remove unused/unwanted dependencies from ember project carefully?

According error message troubles caused with ember-try addon (https://github.com/ember-cli/ember-try ) which run tests on different environments ( check your package.json / node_modules )

If so - you can remove it or just add config file config/ember-try.js like ( https://github.com/vvscode/js--ember-cli-ajax-logger/blob/master/config/ember-try.js ) which define on which versions of ember you want run your tests

There is an open issue on github ember-cli/ember-cli#6016. So my current workaround:

  1. create new ember app
  2. run ember install ember-cli-eslint
  3. remove ember-cli-jshint from package.json
  4. remove ./.jshintrc and ./tests/.jshintrc
  5. remove local node modules rm -rm ./node_modules
  6. reinstall node modules: npm install

DONE!

Also, there is pretty-well detailed description of installation of the eslint for ember: https://github.com/ember-cli/ember-cli-eslint#user-content-disabling-jshint
