Trying to install eslint in recent versions of node (v5.5.0 or 5.9.0).
Running npm install --save-dev eslint on node v5.9.0 (npm v3.7.3) gives me an error:
Invalid Version: 0.0.1alpha1
An ancient version of node (node v0.10.43, npm v1.4.29) installs it without a problem.
Do you know what the problem might be and how to fix it?
UPDATE: Just made sure that eslint loads on node v4.4.1 that is recommended on the Node site as an LTS release. The npm version is 2.14.20.
