Can't build Ijulia in Julia 1.0

Question

After installing the latest Julia (v.1.0) package using conda, on Ubuntu v.16.04, via

conda install -c conda-forge julia

I can't seem to install IJulia. Thus,

(v1.0) pkg> add IJulia

Trying to build ZMQ or BinaryProvider separately gives the same error: that it's unable to open libLLVM.

I haven't encountered the problem when using older versions of Julia, neither an answer to the problem in any of the previous threads. Any ideas?

Answer 1

In regards to libLLVM, check out this link libLLVM

What I would recommend: try removing those packages, adding them back, doing an update, and then resolve.

I am currently converting my code from Julia v0.6 to v0.7 and this is something I have had to do way too much over the last few days.

It may also be worth it to take a look at the specific location in those files where the error is occurring. I have a similar issue with a package and I went into the file and saw that it was testing my OS version, and I was on a non-supported version of MacOs(while unlikely to be your issue, it could be something similar).

Please let me know what happens after the steps I recommended. Good Luck!
