Zipline: Unable to Install on Mac OS Mojave 10.14.2

[prasants]

Dear Zipline Maintainers,

Before I tell you about my issue, let me describe my environment:

Environment

• Operating System: Mac OS Mojave 10.14.2
• Python Version: 3.7.1
• Python Bitness: 64

• How did you install Zipline: (pip, conda, or other (please explain)):

• Step 1: virtualenv venv

• Step 2: source venv/bin/activate
• Step 3: pip3 install cython numpy

• Step 4: pip3 install zipline

• Python packages: Cython==0.29.6
  numpy==1.16.2

Now that you know a little about me, let me tell you about the issue I am
having:

Description of Issue

• What did you expect to happen?
  I was hoping to see Zipline installed without any errors.
• What happened instead?
  I over 67,000 lines of messages, followed by an error message in red, as below:
  Command "/Users/prasant/Documents/Programming/Python/Trading/venv/bin/python3.7 /Users/prasant/Documents/Programming/Python/Trading/venv/lib/python3.7/site-packages/pip install --ignore-installed --no-user --prefix /private/var/folders/xx/hbg55ynx52d_1qpy5npcb0m40000gn/T/pip-build-env-87ox9ql3/overlay --no-warn-script-location --no-binary :none: --only-binary :none: -i https://pypi.org/simple -- wheel setuptools Cython "numpy==1.9.3; python_version=='3.5'" "numpy==1.12.1; python_version=='3.6'" "numpy==1.13.1; python_version>='3.7'"" failed with error code 1 in None

Here is how you can reproduce this issue on your machine:

Reproduction Steps

1. virtualenv venv
2. `source venv/bin/activate'
3. pip3 install cython numpy
4. pip3 install zipline
   ...

What steps have you taken to resolve this already?

Hi @prasants can you try installing Zipline in a Py35 virtualenv? We don't yet have support / packages for Py37

[prasants]

Thanks for your help. I did just that, and this is the error I receive:

Command "python setup.py egg_info" failed with error code 1 in /private/var/folders/xx/hbg55ynx52d_1qpy5npcb0m40000gn/T/pip-install-xid89tab/bcolz/

[rogerjbos]

I am having the same problem. I am using python 3.7.4 on Mac OS 10.14. I can't even figure out how to downgrade python to 3.5 or even install a new version of python 3.5.
Brew switch doesn't work:
(base) Rogers-MacBook-Air:~ rjbos2$ brew switch python 3.5
Error: python does not have a version "3.5" in the Cellar.
python installed versions: 3.7.4
Any suggestions are welcome. Thanks!

[rogerjbos]

Ok, I made a Python 3.5 virtual env using conda, but I still cannot install zipline due to conflicts in the package versions. Any suggestions?

Ok, it seems that I need to downgrade conda first: https://github.com/quantopian/zipline/issues/2514

[fritzybloch]

I am having similar problems on Mojave 10.14.6. I have a Python 3.5.6 environment set up, however conda is 4.7.11. I have tried numerous times to downgrade conda using
conda config --set allow_conda_downgrades true
conda install conda=4.6.11
however this never works. I always get this in return leaving conda in 4.7.11

[rogerjbos]

Honestly, I have never seen a module as difficult to install as zipline.
Only works with a specific version of python (3.5) and specific version of
conda (4.6.11). I think I have it installed, but I still can't run the
basic buyapple.py backrest to test it out. I appreciate all the developers
work, but this is very frustrating.

And what about zipline_live, does that only work with python 2.7?

Hi I only managed to get zipline working in python 2.7 on Mac OS Mojave 10.14.2. conda 4.7.11, else facing the same issue as everyone else on python 3.5 above.

[deuce14]

Still won't install for Python 3.7
Can we just remove the install requirement for 3.5? I'd imagine there's nothing groundbreaking or not backwards compatible from 3.5 to 3.7 (though I skipped 3.5 and haven't written code in it).

[rogerjbos]

I gave up on zipline. I don't think its maintained anymore.

[mosesmc52]

I'm developing using a Macbook air with Mojave 10.14.6.

For the past week, I was having trouble installing, zipline within a python3.5 virtual environment. I narrowed the error down to a C related dependency after observing this error.

ld: library not found for -lblosc

I fixed error by executing within my console

brew install c-blosc 

After, I was able to successfully install Zipline. I hope this helps someone else or at least give them another option to try.

[JayJay-101]

I gave up on zipline. I don't think its maintained anymore.

@rogerjbos can you recommend other package please

[liavkoren]

Using conda + python3.6 worked for me.

[cemal95]

Same here. Conda is the way to go
