Installation with Python 3.5 - NameError: name 'pypath' is not defined

[danielkrizian]

Hi,

NameError: name 'pypath' is not defined is thrown when installing pyq with Python 3.5. On the same machine, it installs fine with Python 2.7. kdb+ version is 3.4, 64-bit licensed.

Thanks

This usually happens when you install pyq using a statically linked python. Check the output of

   ldd `which python`

BTW, what is Python 2.8? As far as I know this has never been released.

[adilbaig]

Hey, 2.8 was a typo. It's 3.5. This is what I get from the virtualenv. It's a stock Python3 (apt install python3) installation in Ubuntu 16.04 (x64)

NB: Internal issue 909.

[sashkab]

Ubuntu provides statically linked Python. They also provide shared libraries which can be installed using apt install libpython3.5-stdlib libpython3.5-dev.

We identified a bug causing installation troubles on Ubuntu and a fix will be available in the upcoming patch release.

[sashkab]

Issue was fixed in PyQ 4.0.2.

We also added a guide on installing PyQ on Ubuntu 16.04.
