KeyError: 'ZK_SYNC_LIBRARY_PATH' #46
Description
My code is:
from web3 import Account, Web3, HTTPProvider
from zksync_sdk import ZkSyncProviderV01, HttpJsonRPCTransport, network, ZkSync, EthereumProvider, Wallet, ZkSyncSigner,
EthereumSignerWeb3, ZkSyncLibrary
import asyncio
def main():
# env = TestEnv()
library = ZkSyncLibrary()
provider = ZkSyncProviderV01(provider=HttpJsonRPCTransport(network=network.rinkeby))
account = Account.from_key("XXX")
async def get_contract_address():
ret = await provider.get_contract_address()
return ret
loop = asyncio.get_event_loop()
task = loop.create_task(get_contract_address())
loop.run_until_complete(task)
contracts = task.result()
w3 = Web3(HTTPProvider(endpoint_uri="https://rinkeby.infura.io/v3/XXX"))
# Setup zksync contract interactor
zksync = ZkSync(account=account, web3=w3,
zksync_contract_address=contracts.main_contract)
# Create ethereum provider for interacting with ethereum node
ethereum_provider = EthereumProvider(w3, zksync)
ethereum_signer = EthereumSignerWeb3(account=account)
# Initialize zksync signer, all creating options were described earlier
signer = ZkSyncSigner.from_account(account, library, network.rinkeby.chain_id)
# Initialize Wallet
wallet = Wallet(ethereum_provider=ethereum_provider, zk_signer=signer,
eth_signer=ethereum_signer, provider=provider)
if name == "main":
main()
however, I get the error.
