Running lates MAC OS. When I try to use PyPlot I get this

but when I do `using PyPlot` immediately afterwards it works fine. Any idea what is happening?
I have tried updating all packages, rebuilding IJulia, PyPlot, PyCall … with no luck.
I’ve been having `using IJulia` in my startup.jl file forever. When I take it out this problem goes away. Why?

Just tried rebuilding my .julia directory from scratch. Problem is still here.

Which version are you using, or just do, to see if anything is holding you back from latest version:
```julia
(@v1.9) pkg> add IJulia@1.23.3
```
PyCall (and PyPlot) have some logic for IJulia:
[https://github.com/JuliaPy/PyCall.jl/blob/2728e20162db3c90198e2828c40e675924c73528/src/pyinit.jl#L260](https://github.com/JuliaPy/PyCall.jl/blob/2728e20162db3c90198e2828c40e675924c73528/src/pyinit.jl#L260)
What’s the difference between IJulia.jl and IPython.jl? I was trying to dig into this and by accident looked into the latter, and installing got a downgrade:
```julia
[18364772] + IPython v0.5.1
Updating `~/.julia/environments/v1.9/Manifest.toml`
⌅ [34da2185] ↓ Compat v4.2.0 ⇒ v3.46.0
```
It needs a compat entry for 4.0. Maybe something similar is happening for IJulia, and holding you back because you use some other package?

I think my IJulia is up to date.
```julia
(@v1.8) pkg> add IJulia@1.23.3
Updating registry at `~/.julia/registries/General.toml`
Resolving package versions...
No Changes to `~/.julia/environments/v1.8/Project.toml`
No Changes to `~/.julia/environments/v1.8/Manifest.toml`
```
On an M1 Macbook things work, but I get this everytime
```julia
julia> using PyPlot
[ Info: Installing matplotlib via the Conda matplotlib package...
[ Info: Running `conda install -y matplotlib` in root environment
Collecting package metadata (current_repodata.json): done
Solving environment: done
# All requested packages already installed.
Retrieving notices: ...working... done
```
Why does `conda install` run everytime?

I just pushed a bugfix. Should be tagged shortly, at which point you can do a package update: [https://github.com/JuliaRegistries/General/pull/66764](https://github.com/JuliaRegistries/General/pull/66764)

Things work in the repl if I put
```julia
using PyPlot
using IJulia
```
in my startup.jl file. If I swap the order I get the error message as when Julia starts up.
However, when I do that my notebooks can’t find the kernel.

After rebuilding .julia for the third time I found that `using TerminalPager` in my startup file seemed to be the problem.

I doubt it; probably you updated to the PyCall version that I [just registered](https://discourse.julialang.org/t/pyplot-woes-in-1-8-0-intel-mac/86138/5) without noticing.

IJulia is to install a Jupyter kernel that runs julia. IPython is to use Python from within the Julia REPL.
