Already tried everything

ccordoba12 commented 2 months ago

Hey @booc24, thanks for reporting. Please try this to see if it helps:

conda install -f python.app

Let us know if that solves your problem.

There is still a problem after installing python.app ❯ spyder /opt/anaconda3/envs/env1/bin/pythonw: line 3: 29705 Segmentation fault: 11 /opt/anaconda3/envs/env1/python.app/Contents/MacOS/python "$@"

ccordoba12 commented 1 month ago

Then you can try to run

conda remove --force python.app

and after that

conda install python.app

to see if that solves the problem.

@ccordoba12 I have the same issue. Brand new device (MacBook Pro M3 Max with the latest MacOS) with a freshly installed Anaconda Distro (today, 28th June 2024). The previously suggested solutions have not resolved the issue for me. The only thing that works is to create a new environment with Spyder 5.4.3, instead of 5.5.1.

ccordoba12 commented 1 month ago

@mrclary, could you check this in your Mac? For that, please download the latest Anaconda and check if Spyder works for you in your computer after installing it.

mrclary commented 1 month ago

I gather from the above comments:

macOS arm64 and/or x86-64 platforms
Anaconda installed for all users (i.e. /opt/anaconda3)
Dedicated Spyder environment (i.e. envs/env1, envs/spyder-env)
Root environment (i.e. /opt/anaconda3/bin)
Spyder 5.5.1

Has anyone tried the latest version, Spyder 5.5.5?

I'll poke around and report back.

mrclary commented 1 month ago

Okay, this issue only affects arm64 and python.app=3 (though I have not tested python.app=2).

the main channel only has python.app versions 2 and 3. Version 3 is what ships with Anaconda and is installed when creating additional environments for Spyder. Version 2 is not available for Python 3.12, only 3.8, 3.9, and 3.11.
the conda-forge channel only has python.app up to version 1.4, but this works.

I recommend creating a dedicated Spyder environment using the conda-forge channel:

(base) >> conda create -n spy-env -c conda-forge --override-channels python=3.12 spyder=5.5.5

This will install Python 3.12 and Spyder 5.5.5, but you can specify whichever Python or Spyder version you like by modifying the command accordingly. python.app=1.4 from conda-forge will be installed and Spyder should launch successfully.

I do not recommend installing python.app=1.4 into your Anaconda base environment or other existing environments that are created with packages from the main channel. Doing so will cause Python 3.12 to be reinstalled from the conda-forge channel and result in a mixed channel environment which may cause other issues.

Thanks for checking this @mrclary! So python-app=2 works well for Python 3.8 to 3.11 in M1 Macs?

mrclary commented 1 month ago

Spyder=5.5.1 + Python=3.9.19 + python.app=2 on M1 works fine. Spyder=5.5.1 + Python=3.11.9 + python.app=2 on M1 does not work:

Traceback (most recent call last):

    from spyder.app.start import main
  File "/Users/ryan/.conda/envs/spy551_py311_defaults/lib/python3.11/site-packages/spyder/app/start.py", line 28, in <module>

Though I don't think this has anything to do with python.app=2. It appears something may be wrong with the python 3.11.9 build from the defaults channel.

ccordoba12 commented 1 month ago

@mrclary, and are there also startup errors with Python 3.12 from the defaults channel?

mrclary commented 1 month ago

@mrclary, and are there also startup errors with Python 3.12 from the defaults channel?

Yes, due to python.app=3. This is the condition for the original post.

mrclary commented 1 month ago

On the defaults channel for arm64:

python.app=3 is broken. This is available for Python 3.8, 3.9, 3.10, 3.11, and 3.12
python.app=2 seems to work, but is only available for Python 3.8, 3.9, and 3.11. But Python 3.11 seems to be broken due to a random package library issue.

Thus, is seems that the only working configuration on arm64 using defaults channel is Python 3.8 or 3.9 with python.app=2. I have found no issues with any configuration using the conda-forge channel.

This actually works for me. I'm using a Mac M1. Thank you!
