Installation issue

[mycotonia3]

<Hello, I have a mac M1 and i am having issues installing cutadapt. I looked at an old issue (#629) and i think it may have something to do with not having the proper dnaoi file. I have Python 3.10.0

I followed these instructions: pip install virtualenv python3 -m virtualenv cutadapt_venv source cutadapt_venv/bin/activate pip install --upgrade pip setuptools pip install --nodeps cutadapt pip install xopen

pip install /Users/toniadebellis/Downloads/dnaio-0.10.0-cp311-cp311-macosx_10_9_x86_64.whl ERROR: dnaio-0.10.0-cp311-cp311-macosx_10_9_x86_64.whl is not a supported wheel on this platform. tried this one too: pip install /Users/toniadebellis/Downloads/dnaio-0.10.0-cp310-cp310-macosx_10_9_x86_64.whl ERROR: dnaio-0.10.0-cp310-cp310-macosx_10_9_x86_64.whl is not a supported wheel on this platform.

would you know what is going wrong from this info?

here is the part prior to the error: toniadebellis@Tonias-MacBook-Pro ~ % pip install virtualenv Requirement already satisfied: virtualenv in /Library/Frameworks/Python.framework/Versions/3.10/lib/python3.10/site-packages (20.21.0) Requirement already satisfied: distlib<1,>=0.3.6 in /Library/Frameworks/Python.framework/Versions/3.10/lib/python3.10/site-packages (from virtualenv) (0.3.6) Requirement already satisfied: filelock<4,>=3.4.1 in /Library/Frameworks/Python.framework/Versions/3.10/lib/python3.10/site-packages (from virtualenv) (3.11.0) Requirement already satisfied: platformdirs<4,>=2.4 in /Library/Frameworks/Python.framework/Versions/3.10/lib/python3.10/site-packages (from virtualenv) (2.4.0) toniadebellis@Tonias-MacBook-Pro ~ % python3 -m virtualenv cutadapt_venv created virtual environment CPython3.10.0.final.0-64 in 277ms creator CPython3Posix(dest=/Users/toniadebellis/cutadapt_venv, clear=False, no_vcs_ignore=False, global=False) seeder FromAppData(download=False, pip=bundle, setuptools=bundle, wheel=bundle, via=copy, app_data_dir=/Users/toniadebellis/Library/Application Support/virtualenv) added seed packages: pip==23.0.1, setuptools==67.4.0, wheel==0.38.4 activators BashActivator,CShellActivator,FishActivator,NushellActivator,PowerShellActivator,PythonActivator toniadebellis@Tonias-MacBook-Pro ~ % source cutadapt_venv/bin/activate (cutadapt_venv) toniadebellis@Tonias-MacBook-Pro ~ % pip install --upgrade pip setuptools Requirement already satisfied: pip in ./cutadapt_venv/lib/python3.10/site-packages (23.0.1) Requirement already satisfied: setuptools in ./cutadapt_venv/lib/python3.10/site-packages (67.4.0) Collecting setuptools Using cached setuptools-67.6.1-py3-none-any.whl (1.1 MB) Installing collected packages: setuptools Attempting uninstall: setuptools Found existing installation: setuptools 67.4.0 Uninstalling setuptools-67.4.0: Successfully uninstalled setuptools-67.4.0 Successfully installed setuptools-67.6.1 (cutadapt_venv) toniadebellis@Tonias-MacBook-Pro ~ % pip install --nodeps cutadapt

Hi, a related issue for M1 Mac installation problem would be #658.

Cutadapt has dnaio as a dependency, and for neither one are there pre-compiled wheels available. I tried just now to get started on creating appropriate wheels for dnaio, but that failed.

I don’t have access to a Mac, so I can only recommend to try the only method that I have heard works, which would be to use Conda as described in Cutadapt’s installation instructions. This will use the x86_64 packages and rely on the emulation built into macOS.

Since you were able to install cutadapt, obviously your C compiler works. Can you try pip install --no-deps dnaio? That should get the latest source and compile it.

Closing this for now. In time, I’ll try to make appropriate pre-compiled versions of dnaio and Cutadapt available, but not at the moment.
