This is my first foray back into using Julia since about a year and had fun playing with DifferentialEquationsExamples in JupyterLab last night using Julia 1.1.1
Just now I updated to Julia1.2 using
brew cask upgrade on my MacBook, and when i started it and went to see the Pkg status it read:
(v1.2) pkg> status Status `~/.julia/environments/v1.2/Project.toml` (empty environment)
Then tried to add Plots to see what would happen:
(v1.2) pkg> add Plots Updating registry at `~/.julia/registries/General` Updating git-repo `https://github.com/JuliaRegistries/General.git` Resolving package versions... Updating `~/.julia/environments/v1.2/Project.toml` [91a5bcdd] + Plots v0.26.2 Updating `~/.julia/environments/v1.2/Manifest.toml` [b99e7846] + BinaryProvider v0.5.6 [3da002f7] + ColorTypes v0.8.0 [5ae59095] + Colors v0.9.6 [34da2185] + Compat v2.1.0 [d38c429a] + Contour v0.5.1 [9a962f9c] + DataAPI v1.0.1 [864edb3b] + DataStructures v0.17.0 [c87230d0] + FFMPEG v0.2.2 [53c48c17] + FixedPointNumbers v0.6.1 [28b8d3ca] + GR v0.41.0 <snipped rest for brevity>
Seems like they were there ?
Quickly skimmed help for Pkg and decided to garbage collect, and ran gc which deleted 420 packages:
(v1.2) pkg> gc Active manifests: `~/.julia/environments/v1.0/Manifest.toml` `~/.julia/environments/v1.1/Manifest.toml` `~/.julia/environments/v1.2/Manifest.toml` Deleted `~/.julia/packages/AbstractFFTs/wfF4f` (26.213 KiB) Deleted `~/.julia/packages/Adapt/zZG7Z` (8.235 KiB) Deleted `~/.julia/packages/Arpack/UiiMc` (1020.292 KiB) Deleted `~/.julia/packages/ArrayInterface/64mDO` (5.534 KiB) Deleted `~/.julia/packages/ArrayInterface/qMMsu` (5.549 KiB) Deleted `~/.julia/packages/Atom/BXRAC` (90.789 KiB) <snipped> Deleted 420 package installations (1003.564 MiB)
OK. so lets start from scratch:
brew cask uinstall julia rm -rf ~/.julia brew cask install julia
try to add Plots back and get this error:
Building GR ────→ `~/.julia/packages/GR/ZI5OE/deps/build.log` ERROR: IOError: getcwd: no such file or directory (ENOENT)
Does anyone know how to prevent an update to Julia not messing up the packages and how to install Plots again ?
