Hi Mikael.

Let's try to get to the bottom of this.

What do you get when you do pip install dukpy ?

sorry - were you intending to attach a second screenshot there?

or are you saying you get the same error when you try to pip install dukpy ?

[mikaelhaji]

I get the exact same error. The second image was basically the same as the first one.

You need to provide full log output for us to be able to help you.

Preferably in text form and not as a screenshot (at least not a screenshot sent through your mail client, since that doesn't seem to be accepted by GitHub).

Seems you are not alone: https://github.com/amol-/dukpy/issues/36

But it should work fine, your system probably lacks some build-time dependency (Xcode tools?).

[mikaelhaji]

Sure, here it is. (logs moved to non-email comment for markdown support)

Email replies makes your comment impossible to format with Markdown and therefore excessively long. So here it is with Markdown:

As the logs indicate, you are missing xcrun (and probably more) from Xcode Developer Tools. This is a common dependency for building almost any software on macOS, and fails for this particular package because it doesn't provide binary wheels for macOS (as indicated in the issue I linked above).

Installing Xcode Developer Tools (or whatever it is called) should fix it.

Closing since this is certainly due to missing Xcode dev tools. It'd be nice if they weren't needed, but it's up to the dukpy devs to fix it by publishing binary wheels.

I had a similar issue, mine was due to missing exports. See here. Running the install procedure of eeg-notebooks once more after doing these 2 exports worked.

Hello, everyone, I'm wondering if there is any update for this issue? since I also met the same problem. my MacBook is Pro M1 with system 13.0.

Thanks

[ErikBjare]

@WeiShaoD Did you install Xcode developer tools as suggested?
