Can't build jupyter notebook with python3 because node-js requires python2 to build #4319
Closed as not planned
Description
I am tryed to install jupyter notebook for python 3 by running:
spack install --verbose [email protected] ^[email protected]~tk~ucs4
==> Error: Invalid spec: '[email protected]~tk~ucs4'. Package python requires version 2.7:2.8, but spec asked for 3.6.0
The reason for this, that node-js depends on python2 to build:
depends_on('[email protected]:2.8', type='build')
As python2 is only required as build depency for node-js is should be possible to build node-js with python2 and use jupyter with python3.
Is it possible to pass this to spack?
