I have written .travis.yml like the example bellow:
language: node_js node_js: - 0.8 - 0.6
Now Node.js was updated to 0.10 and obviously I tried the following change:
language: node_js node_js: - 0.10 - 0.8 - 0.6
The problem is that Travis CI yaml parser runs the 0.1 version instead of 0.10. To fix it you only need to add quotes:
language: node_js node_js: - "0.10" - "0.8" - "0.6"
If you have more troubles, I strongly recommend you to check out the Travis CI docs.
