Hi,

I have solved this libusb issue on macOS with following command.

brew rm libusb --force

brew install libusb

I have pyinstaller version 3.6 and it using python 3.7.

I believe the problem is that some modules/libraries did not get installed properly - see above :

import tornado

ModuleNotFoundError: No module named 'tornado'

Likely, installing those module manually would solve the problem. However, I dont have time for this for now. I have others issues to solve before returning to that topic.

nrfutil work fine with Terminal.app for DFU usage. I have not tried the other feature yet.

Thanks

Hi,

Have you installed pyinstaller using 'pip3 install pyinstaller' ? Did you verify the version using 'pyinstaller --version'?

Maybe these links could be of help?

I believe that I have found the solution. I have just follow my idea above and found the pip uninstall command.

What I have done is:

in mac terminal.app, uninstall nrfutil by typing:

1. pip3 uninstall nrfutil // use pip3 to specify python3, if permission denied, use sudo before and enter password.

2. retype: pip3 uninstall nrfutil // make sure that all the file are gone. Delete those remaining manually if needed.

3. Follow the installation instruction from : https://infocenter.nordicsemi.com/pdf/nrfutil_v1.7.pdf, but replace all installation pip command by: sudo pip 3 . This will avoid permission denied error and install the file in python3 folders. You also have to replace python commands by: python3.

I have used the installation procedure in section from the above document without difficulty : 2.2 Installing from sources. : Typing: nrfutil --help confirm that the program is now functional.

I have tried the following command to create a self-contained executable version of nrfutil, without success. : pyinstaller nrfutil.spec

The installation log indicate that several missing module that could not be import. The command have generate an non-functional installation package. Here a partial list of the errors. At this point I will just use the nrfutil with terminal command and report if I have problems later. I want to use the DFU utilities.

Partial log report for pyinstaller nrfutil.spec:

Hi Marjeris,

i ran pip3 install -U setuptools and as you can see, it says Requirement already up-to-date..

Notice that I also running python3.7, as indicate earlier in the post. Also, NrfUtils 6.0.0 was working before the latest upgrade, few days ago.

_____

SLMini-I5-172:~ slareau$ pip3 install -U setuptools

Requirement already up-to-date: setuptools in /Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages (45.1.0)

________

Pip -- version give me:

_______

SLMini-I5-172:~ slareau$ pip --version

pip 19.3.1 from /Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages/pip (python 3.7)

________

I am using pip and python 3.7 for programming currently without problems.

I have tried to download and go back to nrfutil version 6.0.0 and it don't work anymore - same error as V6.0.1.

I would like to erase everything and restart from scratch but I am not sure what file was installed. I don't want to accidentally delete file that are used with my other program that use python

Hi,

The installation instructions are general for all OS, but if you have multiple versions of Python installed in your system you need to check that you are using the right version. In the Installing instructions for nRFutil it's stated that you should use Python 3.7 or later.

The sudo requirement is probably because of local settings / install permissions settings in your computer.

Could you double check your python enviroment for pip install using command 'pip --version'? It looks like you are using the python 2 enviroment instead of python 3. Try 'pip3' instead.

Did you run 'pip install -U setuptools' before installing the requirements?

Have you installed pyinstaller?

Best regards,

Marjeris

After the install command, I had the following warning , but the rest of the processs seems OK.

SLMini-I5-172:pc-nrfutil-master slareau$ sudo python3 setup.py install

Specific installation instruction for OsX would be nice since command differ from what is in the instruction.

Had to use sudo and python3.

Following the instruction, I have download tnrfutil installation pkg from Github.

In Terminal.app I navigate to the folder and type : pip install -r requirements.txt

Listing says that all requierent were satisfied, except this line :

Ignoring antlib: markers 'sys_platform == "win32"' don't match your environment

I assume that Ok, its a Mac.

I have tried to run nrf_util without installation and this append:

The // OSError: dlopen(libusb-1.0.dylib, 6): image not found // is the one I got previously - see beginning of the post

To install nrfutil, the python setup.py install does not work - it try to install the program with python 2.7 framework. I had to use python3 setup.py install

and then got the error at the end of a long list:

error: [Errno 13] Permission denied: '/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages/easy-install.pth'

I had to use the command: sudo python3 setup.py install, and it work.

I have then tried to run the command : pyinstaller nrfutil.spec

and the command was not found.

***

SLMini-I5-172:pc-nrfutil-master slareau$ pyinstaller nrfutil.spec

-bash: pyinstaller: command not found

*****

Typing the command: nrfutil -- help give and a long list ending by the following error:

OSError: dlopen(libusb-1.0.dylib, 6): image not found

Could it be that a file is misplace during the installation ? Please look at the screenshot.

Hi,

Can you try to reinstall nrfutil from sources (using pip)?

I have just notice that nrfutil come with the libusb package. have tried to reinstall nrfutil with the following command as stated in the nrfutil v1.3 document find on the web:When installing on macOS, you might get an error about the Python module six. In this case, enter the following command instead

pip install --ignore-installed six nrfutil

When generating the private key, I still have the same error :

OSError: dlopen(libusb-1.0.dylib, 6): image not found
