node-gyp rebuild issue when installing dependencies for wallet

Question

I am attempting to build wallet from source but following the instructions in the README. My motivation is I'm interested in a hardware wallet concept / wallet projects in general.

Running OS X 10.12.6 and I installed all prereqs listed in the wallet repo.

$ git clone https://github.com/iotaledger/wallet

$ cd wallet

$ git clone https://github.com/iotaledger/iri

$ cd iri

Following iri doc:

$ mvn clean compile

$ mvn package

[INFO] BUILD FAILURE
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-surefire-plugin:2.12.4:test
[ERROR] ... etc etc

$ mvn package -DskipTests=true

I confirmed that there are jars built in wallet/iri/target

$ cd ..

Follow wallet docs:

$ npm install

$ npm install --python=python2.7

It seems to be an issue with node-gyp specifically w node-gyp rebuild

Does anyone have an idea what the issue might be?

Answer 1

The issue was I had Python 3 installed @ ~/miniconda3 so even thought I was running the install script with Python 2.7 something else, I think electron, was referencing the Python on my path or something like that which was Python 3.

I rm -rf ~/miniconda3 then rm -rf node_modules and its working.
