All fixed. Read @giordano’s post and my last one.

Just installed 1.7 on M1 mac. Started from scratch with no .julia directory.

Tried to fire up a notebook and got this

```julia
julia> notebook(;dir=pwd())
install Jupyter via Conda, y/n? [y]: y
[ Info: Downloading miniconda installer ...
ERROR: Unsupported miniconda platform: MacOSX-arm64

```

What should I do?

Try [reading the documentation of `Conda.jl`](https://github.com/JuliaPy/Conda.jl/blob/bc304f8f8dad0cf78fbba151bed61ebe26fe6589/README.md#using-miniforge)

This is actually the default in the `master` branch of `Conda.jl`, but it didn’t make it to a release yet

Thanks,

I use conda only with notebooks and have no clue about fixing problems like the one I have.

I tried to understand your respose as best I could and (1) typed your two lines, (2) restarted Julia, (3) typed them again, and (4) restarted julia.

notebook started up, I got to my notebook, and then

```julia
using PyPlot

```

failed with

```julia
ERROR: InitError: PyError (PyImport_ImportModule

The Python package matplotlib could not be imported by pyimport. Usually this means
that you did not install matplotlib in the Python version being used by PyCall.

PyCall is currently configured to use the Python version at:

/Applications/Xcode.app/Contents/Developer/usr/bin/python3

```

Trying `using PyPlot` from the REPL got the same result.

I do not use python at all and I am in over my head.

I will go back to 1.6.3 or try the intel version of 1.7 on my M1 mac.

Same issue with PyPlot in the REPL for 1.7.1.

Back to intel and rosetta

I figured out my problem.

```julia
ENV["PYTHON"]=""

```

somehow got erased from my startup.jl. Putting it back and building PyCall and PyPlot did the job.
