Setting up

[bitcartel]

@arcalinea @arielgabizon

Following the set up instructions I run into problems:

Using venv, python -V returns Python 3.5.2 which is expected.

Next step, pip install zbxcat returns:

  Could not find a version that satisfies the requirement zbxcat (from versions: )
No matching distribution found for zbxcat

[arielgabizon]

I get the same thing. @arcalinea could it be because of moving zbxcat to zcash-hackworks?

[prestwich]

Use pip install -e ./zbxcat to install the local project folder and keep it editable (-e) for development. Omitting the ./ has pip check package directories instead of local folders.

Also works:
cd zbxcat && pip install -e .

[arielgabizon]

That worked!

[johanssonlc]

Above got me further but then it failed on some dependency:

`(venv) crypto-dev@alpha2:~/zcash/xcat$ cd zbxcat && pip install -e .

Any idea what the problem might be?

Do you have levelDB installed? It is not packaged with plyvel. Try sudo apt-get install libleveldb1 libleveldb-dev

Also, you can wrap terminal output with three backticks: ``` to create

code blocks.

[johanssonlc]

Didn't work unfortunately. FYI I am on Ubuntu 16.04.3 LTS, if that helps. 2017-10-20 2:20 GMT+02:00 James Prestwich <[email protected]>:

@johanssonlc

Can you try according to this answer here
okfn/piati#65

Also maybe try putting zbxcat in the root instead of in a subdirectory?

If it doesn't work we should ask @arcalinea again.

btw @frdwrd did you manage to use the xcat code?

[prestwich]

@johanssonlc I think that @arielgabizon is right. Try sudo apt-get install python3-dev and then installing again.

@arielgabizon Yeah, I have it set up and running with regtest daemons. I also set up a test runner and requirements.txt and implemented a bunch of unit tests.

[johanssonlc]

That did the trick. Thanks! 2017-10-20 22:58 GMT+02:00 James Prestwich <[email protected]>:

[arielgabizon]

Awesome! Can you specify exactly what did the trick so we can improve the instructions?

[arielgabizon]

Ohh sudo apt-get install python3-dev?

[johanssonlc]

Exactly, installing python3-dev solved it. Den 22 okt. 2017 21:03 skrev "Ariel" <[email protected]>: Ohh sudo apt-get install python3-dev? — You are receiving this because you were mentioned.

[arielgabizon]

@arcalinea should we add sudo apt-get install python3-dev in the beginning of the installation instructions?
