pip3 install websocket-client

[lykkedk]

  Hello here friends 

Well, working on a DSP engine (digital sound processing) and i need the python3 websocket-client for it.

i can install it with this :

Code: [Select]

tc@DSP-Player:~$ sudo pip3 install websocket-clientEverything is working then, but it does not survive reboot ofcause.

Whats the best / easiest way getting there?

Thanks; Jesper...

The most efficient way is to compile it and make an extension.

[lykkedk]

Yes, you are ofcause right.
But.

Is it okay to make a directory which contains the package(s) perhaps like:

Code: [Select]

[sudo]

mkdir /temp
cd /temp
mkdir pywebsocket
cd pywebsocket
mkdir -p usr/local/bin/python3.7/site-packages (or where they are excatly!)
(maybee split out more dirs here)

cd /temp
mksquashfs pywebsocket py_websock.tcz


Then move it to tcedir & add to .onboot.lst
Would it be okay, or bad idea?

Jesper.

Many python apps install easily, i.e.

Code: [Select]

$ tce-load -i compiletc python3.6-dev
$ tar xf python_package.tar.gz
$ cd python_package
$ python3.6 setup.py build
$ mkdir /tmp/pkg
$ sudo python3.6 setup.py build install --root=/tmp/pkg
Then, to make an extension:

Code: [Select]

$ tce-load -i squashfs-tools
$ cd /tmp
$ sudo mksquashfs pkg/ python_package.tcz
In addition, to make things smaller, you can delete any _pycache directories before making the extension

Yes... look's like i could try that 

Is there a way to see which package websocket-client the pip3 installs on the raspbian???
Better to use a know working one 

Jesper.

Usually when you use the pip install command it tells you what it is installing.

You could also use the tar.gz file here https://pypi.org/project/websocket_client/#files
