Running on Ubuntu 16.10, while I did not have such problems with NS 2.0.0

I experienced the same issue. The result of tns prepare android --log trace > build.log can be seen at the attachment.
I tried to identify the bug.
It may be at traverseDependency (source nativescript-cli/lib/tools/node-modules/node-modules-dependencies-builder.ts), because {"name":"d","directory":"/home/myproject/node_modules/d","depth":0} shows up many times in the log.

I solved my issue by removing the number-generator package, because it has an incorrect dependency environment for eslint causing a cyclic import for es6-iterator. To permit use this package I changed it's eslint to devDependencies of package.
Also i believe this routine should be fixed to prevent similar issues. tx.

@rLoka, @silveirado can you provide steps to reproduce and the version of cli you're using?

[rLoka]

@Plamen5kov I updated from 2.0.0 to 2.5.0 and that is what happened. I am on Ubuntu 16.10.
Here is the project source https://github.com/Non-BinaryT/OfficeEquipmentTracker .. you can try building it yourself.

Thank you @rLoka, I managed to reproduce the problem and will investigate.

You can't have nativescript as a dependency, if you're going to install it locally, install it as a devDependency or even better use it globally.

to fix your issue:

• npm uninstall nativescript --save
• npm install -g nativescript
• tns build android

[silveirado]

Steps to reproduce this issue:

$ tns create issue-2561 --ng
$ cd issue-2561
$ npm i -S lodash
$ npm i -S moment
$ npm i -S nativescript-cardview
$ npm i -S nativescript-sqlite
$ npm i -S nativescript-statusbar
$ npm i -S nativescript-websockets
$ npm i -S number-generator
$ tns platform add android
$ tns prepare android
$ echo "Everything ok"
$ npm i -S eslint eslint-plugin-compat
$ tns update
$ tns prepare android

Result:

I know that the eslint eslint-plugin-compat packages must be in devDependecies, it has been fixed at PR [#3] (MartinHelmut/number-generator#3) from 'number generator' package. But indeed miss happens may occur.

@silveirado thank you, for the detailed steps to reproduce. It's a node restriction on the size of arguments you can call it with, we'll fix it as soon as possible.
Until we do, all we can provide as a workaround is to install any non-production dependencies as devDependencies.
