I am following the simplelog tutorial at http://yottadocs.mbed.com/tutorial/tutorial.html

Things I have tried,

1. system time got using python is in sync with UTC.
2. pip installation "sudo pip install pyasn1 --upgrade" reports already up-to-date.

Thanks

Your version of the requests package is too old. Run pip install -U requests first. (yotta requires requests>=2.4.1, which is specified in its setup.py, so this should have been updated when yotta was installed!)

[shahab5]

@autopulated Thanks for reply.Pip says its upto date.

pip install -U requests Requirement already up-to-date: requests in /usr/lib/python2.7/site-packages

[autopulated]

ah I misread the version in your error message – you do have >=2.4.1, but still only version 2.6.2 (the latest is 2.9.1).

So possibly this is another setuptools issue – It's worth trying installing the latest version of that (pip install -U setuptools), and also updating to the latest yotta, which doesn't use pgk_resources any more when running commands (pip install -U yotta).

[shahab5]

@autopulated Updated pip using

dnf install python3-pip

pip install -U setuptools

How to remove the existing yotta (0.15.2),

pip uninstall yotta Cannot uninstall requirement yotta, not installed

But yotta command exists.

[autopulated]

which yotta will tell you where the yotta that's being run is:

It's possible that you have two separate python installations – python 2, and python 3. I'm not sure how Fedora handles this, but you might have separate pip2 and pip3 commands for installing/uninstalling programs for each of them.

The installation is failing because binaries aren't available for your platform, and you're missing the python development headers needed to compile the cffi module. I think def install python3-devel should install them.

[shahab5]

Thanks it worked!!!

pip2 uninstall yotta removed existing yotta

Installed development headers and yotta using, dnf install python3-devel
pip install -U yotta
