Python 3.4 does not recognize package

Question

On my raspberry pi 3 model B, I run linux raspberrypi 4.4.48-v7, which is a debian distribution / flavor.

I installed python 3.4.

sudo pip install enum34

returns -

Requirement already satisfied: enum34 in /usr/local/lib/python3.4/dist-packages.

I am trying to install and run this open source project to interact with bluetooth for microbots (but I believe my problem is with python configuration) -

https://github.com/VRGhost/PyPush

I installed the package and requirements, but when I try to download / maintain the package as follows -

./bin/serve.sh --ble_driver bluegiga --ble_device /dev/tty.usbmodem1 web_ui

I get -

/usr/bin/python: No module named enum; 'PyPush' is a package and cannot be directly executed

I believe the line in serve.sh that fails is

exec python -m PyPush $*

How can I make python recognize PyPush as a module? The material I found online refers to the enum34 that is installed.

Answer 4

pip Python 2.x, pip3 Python 3.x. , Python PyPush. print . GitHub print ... print(...), , , Python 2.x, Python 3.x. 2.x.

Requirement already satisfied: enum34 in /usr/local/lib/python3.4/dist-packages.

, enum Python 3.x,

/usr/bin/python: No module named enum; 'PyPush' is a package and cannot be directly executed

/usr/bin/pythonon most distributions it still stands for Python 2.x. You can check which version (2.x or 3.x) s /usr/bin/python --versionto make sure.

Long, short speech - you have a package enumfor Python 3.x, PyPush is written for Python 2.x, and you also need backported enumfor Python 2.x.
