在 Ubuntu v.16.04 上使用 conda 安装最新的 Julia (v.1.0) 包后，通过
conda install -c conda-forge julia
我似乎无法安装 IJulia。因此，
(v1.0) pkg> add IJulia

Building IJulia ─→ `~/.julia/packages/IJulia/4VL8h/deps/build.log`
尝试分别构建 ZMQ 或 BinaryProvider 会产生相同的错误：它无法打开 libLLVM。
在使用旧版本的 Julia 时，我没有遇到过这个问题，也没有在之前的任何线程中解决这个问题。有任何想法吗？
