I am trying to setup pyethapp development environment. I used
($ mkvirtualenv pyethapp)
$ git clone https://github.com/ethereum/pyethapp
$ cd pyethapp
$ USE_PYETHEREUM_DEVELOP=1 python setup.py develop

However, I am getting the error as:
Writing /var/folders/rp/l3y_m3392dqcgc_77m8f_ks00000gn/T/easy_install-9ohquD/ethereum-2.1.1/setup.cfg

error: Setup script exited with error in ethereum setup command: 'tests_require' must be a string or list of strings containing valid project/version requirement specifiers; Unordered types are not allowed

Can someone please help?

@simrankedia Hi, I also tried am getting the same error. If you by any chance figure out the solution.
Sai Chaitanya Tirumerla
hey @simrankedia , @faizan2590 - I manually installed ethereum == 2.3.0 from https://pypi.python.org/simple/ethereum/ and change requirements.txt file with ethereum=2.3.0 instead of 2.1.1 and pycryptodome=3.4.7. Try again to install

is pyethapp:master the most stable branch?
Sai Chaitanya Tirumerla
@tidymonkey81 i would guess so - i used develop branch though , i havent had any problems.
Anyone knows about this problem?
running app.py from PyCharm
from . import config as app_config
ValueError: Attempted relative import in non-package
Sai Chaitanya Tirumerla
hey @pblin - how are you running it, do you see the same issue when you are running as python pyethapp/app.py or just running as python app.py
WARNING:eth.sync.task no protocols available

I want to run casper testnet
who know other casper testnet enode ?

Hi folks, I want to connect to my privet blockchain using PyEthApp. My privet blockchain was upped with geth

"geth --datadir ./myDataDir --networkid 1114 --rpc --rpcport "8545" --rpccorsdomain "*" console 2>> myEth.log"

, so I am trying to connect using following

"pyethapp -c eth.network_id=1114 -b enode://....@[::]:30303 run --console".

And I always get following error “Address already in use: ('', 30303)”

Could any help me? Thanks a lot.

pyethapp sync the blocks too slow,Can it be used in an exchange code?

Guys, can someone answer, is it possible to connect to pyethapp node with Mist?
Alexander Mühle
I havent tried it but you should be able to connect to pyethapp via http RPC, you can't use IPC however, so it will be less secure @osteotek
Arthur Tazhitdinov
@alexandermuehle yeah, I'm getting no luck with usual way of "--rpc http://HTTP://". Should I enable API modules somehow when starting pyethapp node, like with geth?
Alexander Mühle
Pyethapp rpc port is 4000
Arthur Tazhitdinov
I remapped port to 8545. I'm able to connect to it from python scripts with web3.py, I just can't connect mist (or geth) to it

Hi guys when I enter pyethapp run im getting an error stating resource temporarily unavailable. Anyone have a suggestion?
Piper Merriam
@/all pyethapp does not have a dedicated maintainer or development team and is likely to be formally deprecated/sunseted. If you are looking for a python ethereum client come check out trinity (currently found in the py-evm repository and under the py-evm gitter channel ). It is built on top of pyevm (replacement for pyethereum). It is actively maintained and developed and quickly approaching the first public alpha release.
Which Web3.py version do you trust the most?
See https://github.com/ethereum/web3.py/issues/808#issuecomment-385982456
how can I set a private network in
pyethapp with a couple of local nodes?
or a local testnet with a couple of nodes?
Matheus Melo
hey guys. i'd like to understand the ethereum blockchain and smartcontracts, like how it works in code level. for example, which parts of the code are used when a smartcontract is created and performed. how and where can i learn this?

probably this is the issue : Link to http://pypi.python.org/simple/ ***BLOCKED*** by --allow-hosts but i am not getting that for other projects ...
@vesellov pyethapp is being deprecated https://github.com/ethereum/pyethapp/pull/297/ go try trinity instead https://github.com/ethereum/trinity
