pip install brunel error

[opokualbert]

Hello -
I tried to pip install brunel but I get this error:
Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-install-oxnvqc7e/brunel/

Please take a look into this issue and help out.
Thanks!
Albert.

I'm having trouble installing brunel with pip too. It just started today, after upgrading to pip 10.0.0.

$ pip install brunel

    .....
    Complete output from command python setup.py egg_info:
    Traceback (most recent call last):

Brunel/python/setup.py

Line 30 in 937a26c

pip.main(['install', 'jupyter-pip']); cmdclass = importlib.import_module('jupyterpip').cmdclass

It looks like the 10.0.0 version of pip has removed the pip.main() function and buried it at pip._internal.main

(observed with Python 2.7 and Python 3.6)

@opalbert If your problem is the same as mine, you can temporarily work around the issue by explicitly installing jupyterpip manually before installing brunel

pip install jupyter-pip

@danfike Thank you for your suggestion, the installation almost worked except that I get this new error which seems to me I need to install Java/JDK:
"RuntimeError: No Java/JDK could be found. I looked in the following directories:

/usr/lib/jvm/jre-1.7.0
/usr/lib/jvm/jre-1.6.0
/usr/lib/jvm/jre-openjdk
/usr/lib/jvm/java-1.6.0-openjdk-1.6.0.41.x86_64
/usr/lib/jvm/jre
/usr/lib/jvm/jre-1.6.0-openjdk.x86_64
/usr/lib/jvm/jre-1.7.0-openjdk.x86_64
/usr/lib/jvm/java-1.7.0-openjdk-1.7.0.171.x86_64
/usr/lib/jvm/java-1.7.0-openjdk-1.7.0.161.x86_64

Please check that you have it installed.

If you have and the destination is not in the above list, please find out where your java's home is, set your JAVA_HOME environment variable to that path and retry the installation.
If this still fails please open a ticket or create a pull request with a fix on github:

Yes, you'll need Java, and you'll need to ensure JAVA_HOME is set accordingly.

After installing pip install jupyter-pip on a new machine, pip install brunel works.
Thanks all.
