Error during deploying the sample crowdsale

[zoltan-molnar]

Hi all,

I don't know if this is my fault or not, but I couldn't deploy the sample code. My first step was to setup everything according to this: https://ico.readthedocs.io/en/latest/install.html
Then, I started parity with this command: parity --chain=kovan. I created an address, I also validated it on the main net, then I got some tokens on kovan.
After this, I tried to run the following command: deploy-contracts --deployment-file=crowdsales/allocated-token-sale-example.yml --deployment-name=kovan --address=0x00D75b582f6387dDb9fc0f7517350Ed7Ce6B50De

First I got the following error:

(venv) user-machine:ico user$ deploy-contracts --deployment-file=crowdsales/allocated-token-sale-example.yml --deployment-name=kovan --address=0x00D75b582f6387dDb9fc0f7517350Ed7Ce6B50De

I figured out that this may be, because the port is wrong in populus, so I changed it in populus.json:60 from http://127.0.0.1:8547 to http://127.0.0.1:8546.

It went through on that error, but I got a new one:

Any ideas what did I miss or is this really a problem with the package?

[jonasjuan]

i'm having the exact same issue. Exact output with the JSONDecodeError. Help please?

I'm running on ropsten though.

EDIT : think i managed to fix it. had to modify populus to point whatever net youre using to 8545. Works for me.
