Install Plots: ERROR: KeyError: key "Zlib_jll" not found

New to Julia

Fresh install and fresh active project…

(Julia) pkg> add Plots
Resolving package versions…
ERROR: KeyError: key “Zlib_jll” not found

Any Ideas?

What version of Julia?

3

1.5.1

4

what is the project you activated? i.e why does it say (julia) instead of (@1.5)

5

I’m in a folder named “Julia”

(Julia) pkg> activate .
 Activating environment at `...\Julia\Project.toml`
6

Nevermind… it started working… Not sure why.

7

Do you remember what you changed to make it work? I have the same problem, but it does not seem to magically disappear when I retry

Version: 1.5.1
Windows, 64 bit

8

Might be fixed in the upcoming 1.5.2.

Please paste the full stacktrace when this happens.

Unfortunately, I don’t think I changed anything significant.

I’m not sure how related this is to the problem but, setting up environments has been problematic and I’ve been receiving other errors. I have resorted to deleting the entire “general” folder where ~\general\registry.toml lives. Julia is frequently saying that it doesn’t exist when attempting to set up a new environment. Not sure if this issue is due to the package, pkg module, or a side effect of a deeper issue. I only received this error for that specific package.

I experience similar issue when using Julia environments in Windows.

For example, after an activate . in a new folder, trying to add Flux results in the following:

(test) pkg> add Flux

I am experiencing the same problem. Do anyone find the issue?
