nRFConnect 1.1.0 / Installing on macOS / Installing additional Python dependencies problem

[Matt]

My system: MacBook Air with macOS 10.14.6, Xcode 10.3, with sdk at /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.14.sdk

When I ran the pip3 command to install the additional python dependencies

pip3 install -r zephyr/scripts/requirements.txt

I ran into the following warning:

building 'hid' extension
creating build
creating build/temp.macosx-10.14-x86_64-3.7
creating build/temp.macosx-10.14-x86_64-3.7/hidapi
creating build/temp.macosx-10.14-x86_64-3.7/hidapi/mac
Compiling with an SDK that doesn't seem to exist: /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.15.sdk
Please check your Xcode installation

I have no idea how and why MacOSX10.15.sdk is used for this 'hid' extension building given that my macOS is 10.14.6.

Any ideas?

[Vidar Berg]

I was finally able to replicate the same build error. Not sure if it was because I updated to Python 3.7.5 or if it was that I uninstalled it and re-installed with the following command: pip3 uninstall hidapi && pip3 install --user --no-cache-dir hidapi. I have to continue to debug this tomorrow, but if you want you could try to downgrade to 3.7.4 and see if that helps. 

[Matt]

How do I downgrade to 3.7.4?

[Vidar Berg]

Sorry, I thought it would be easy to downgrade, but it seems like that is not the case. At least not for this package. However, I was able to fix the build issue on my setup by updating to Xcode v11.2.1, which does include MacOSX10.15.sdk. Is it an option to update xcode? 

[Matt]

Let me try today and get back to you tomorrow.

[Matt]

Good news: With the Xcode v11.2.1 installed the "pip3 install --user -r zephyr/scripts/requirements.txt" works now!

Bad news: the next pip3 install -r nrf/scripts/requirements.txt fails, something about cannot find "git2.h"?
