@lautsevich Does this also occur with newer versions of npm?

[lautsevich]

I don't know. I used only the common configuration of Travis.

[kenany]

@lautsevich Please at least try updating:

before_install:
  - npm install -g npm
  - npm --version

[lautsevich]

@KenanY, thx! I moved forward. But I have new troubles now:

Then I've added following lines to my Travis config:

sudo: required
before_install:
    - sudo apt-get update
    - sudo apt-get install nodejs

I moved even further. And I've got a new problem:

Then I've configured my npmjs.com credentials again but it did not solve the problem. =(

[kenany]

@lautsevich Are you the owner of the travis package?

[lautsevich]

It's just a test package and i really forgot to change credentials in package.json. I've done this and it works now. Thank you for your help!
