Package Versioning for Julia Projects

Resolved GLM installation error

Update: Thanks to JuliaRegistries/General#647, the version cap of the package Distributions has now been removed, so that one can directly install the package GLM along with Distributions v0.19.2. Background I’m reading the book Statistics with Julia, which makes use of GLM. Problem I encountered the following error, which I posted in the issue GLM.jl#311. (v1.1) pkg> add GLM Resolving package versions... ERROR: Unsatisfiable requirements detected for package GLM [38e38edf]: GLM [38e38edf] log: ├─possible versions are: [0. [Read More]

Juno Installation 2019

Log of system-wide config

Goal To install Juno for convenient development in Julia. Problem After Juno installation, I received the following error. Analysis From the error message, the system had tried to find an executable file julia, which would then be executed by the shell /bin/sh. Nonetheless, it’s absent from the system’s environment $PATH, so Juno couldn’t find it. I’ve only changed my $PATH in ZSHRC, which is user-specific. Solution This Stack Overflow question about $PATH setting on *nix has provided various solution. [Read More]

Install Julia From Source

Custom built Julia from GitHub

Goal To get Julia installed as a normal user on RHEL 6. Motivation “Julia talks like Python but walks like C.” To do statistics more efficiently. The compiled binaries often contain install scripts which put files to shared folders under /usr. Consequently, they have to be run as sudo privileges. That drove me to start this lengthy Julia compilation. Installation Without sudo privileges, I’ve chosen to compile Julia from source. [Read More]
