PyCall installation problems

Hi all, I posted the problem in the PyCall page but it really belongs here. Please look at where I have a problem installing PyCall.

I would appreciate any pointers on how to fix this.

It is firewall issue. You may have to contact your company’s network admin. Tell them the symptom in detail, then usually they will give you necessary environment variables to set.

I tried it at home without the firewall, and that had the same problem.

So here is the output that demonstrates that Conda installs without errors but PyCall does not.

(v1.3) pkg>

I am going to try installing Julia 1.3.1 to see if a clean install does the trick.

Try conda install numpy. I am pretty sure that it will fail for the same reason: somehow, access to conda repo ( is being blocked.

Network accessibility is not the problem. Problem clearly says that the target URL doesn’t contain the file current_repodata.json which the PyCall tries to call. is not existing in the anaconda repo channel where as repodata.json file exits.

Question for me as well is, how to update this meta information?

I have the exact same problem. Have you solved it yet? Because, I can’t crack it.

I just went to the JuliaPro distribution and everything seems to work now.
