调研方向
使用提供的 Julia 1.8/1.9 启动命令、LD_LIBRARY_PATH，以及在 macOS 上依次执行 using Conda、using PyCall 和 using PyPlot，重现该故障。检查报告中的 Conda matplotlib 安装以及之前的 MKL dylib 冲突；当 using PyPlot 完成且未发生挂起或以 Killed: 9 退出时，即表示完成。

描述
using PyPlot hangs or kills julia 1.8.5 or 1.9.0 on MacOS
Synopsis
using PyPlot hangs julia. No progress for >10 hours. No error message. User ^C exits julia with Killed: 9.
With repeated testing, behavior has evolved to crash immediately with Killed: 9, where it had hung.
Demonstration
Carefully recursively force-removed the conda directory $HOME/.julia/conda, which seems to be shared between julia 1.8 and 1.9.
Start julia, making sure dynamic dependencies are consistent with the conda python installation.
LD_LIBRARY_PATH="$HOME/.julia/conda/3/lib" /Applications/Julia-1.8.app/Contents/Resources/julia/bin/julia
or
LD_LIBRARY_PATH="$HOME/.julia/conda/3/lib" /Applications/Julia-1.9.app/Contents/Resources/julia/bin/julia
Make sure julia is using the conda python distribution and build PyCall.
ENV["PYTHON"]=""
]build PyCall
Building Conda ─→ `~/.julia/scratchspaces/44cfe95a-1eb2-52ea-b672-e2afdf69b78f/e32a90da027ca45d84678b826fffd3110bb3fc90/build.log`
Building PyCall → `~/.julia/scratchspaces/44cfe95a-1eb2-52ea-b672-e2afdf69b78f/62f417f6ad727987c755549e9cd88c46578da562/build.log`
...
Quit and restart julia, then run
using PyPlot
Since we started by wiping ~/.julia/conda, matplotlib is not installed. Conda is automatically deployed to install it:
[ Info: Installing matplotlib via the Conda matplotlib package...
[ Info: Running `conda install -y matplotlib` in root environment
...
Executing transaction: done
It hangs there.
Kill julia with ^C -> Killed: 9.
Try again now that matplotlib is installed:
LD_LIBRARY_PATH="$HOME/.julia/conda/3/lib" /Applications/Julia-1.8.app/Contents/Resources/julia/bin/julia
ENV["PYTHON"]=""
using PyPlot
Result: It just hangs immediately. So, I think probably conda installs matplotlib (maybe OK?), but julia is unable to use it.
I have to kill julia with ^C -> Killed: 9.
Trying again.
LD_LIBRARY_PATH="$HOME/.julia/conda/3/lib" /Applications/Julia-1.8.app/Contents/Resources/julia/bin/julia
ENV["PYTHON"]=""
using Conda # returns
using PyCall # returns
using PyPlot # crashes
Killed: 9
Crashes and exits.
Even wiping .julia/conda again, it just crashes now with Killed: 9
Background
PyPlot had previously been working for me.
The first sign of trouble was an MKL dylib conflict error message and crash when running using PyPlot.
Unfortunately after many ^Cs I can't find that error message.
I updated julia's conda after that. Then I got the behavior reported above.
