node-gyp rebuild / error: redefinition of '_NanEnsureLocal'

[cfrancomme]

Versions : "node":"4.2.1","npm":"3.3.9", bufferutil@1.1.0 This is happening straight after getting actual version from github

Anyone have had this issue with recent modules ?

bufferutil@1.1.0 install /Users/x/Documents/myworkspace/gekko/node_modules/bufferutil
node-gyp rebuild

same here on node v5.5.0

bufferutil is not a as a dependency of gekko anymore. I assume you had this error while npm installing. If you still have this issue, please comment here.

Upon further research I figured out this is caused by an outdated ws (version 0.7.1) being required by the mexbt dependency. I removed the dependency for now to remove any confusion.

If you want to run gekko on mexbt, please install it manually like so:

npm install mexbt
