PDB是干嘛的？

[kenneth]

blockchain-py/cli.py(69)create_blockchain()
-> bc = Blockchain(address)
(Pdb)

去掉后RuntimeError: generator raised StopIteration

Traceback (most recent call last):
  File "/Users/Documents/Github/blockchain-py/blockchain-py/blockchain.py", line 119, in blocks
    raise StopIteration
StopIteration

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "cli.py", line 121, in <module>
    create_blockchain(args.blockchain_address)
  File "cli.py", line 71, in create_blockchain
    utxo_set.reindex()
  File "/Users/Documents/Github/blockchain-py/blockchain-py/utxo_set.py", line 25, in reindex
    utxos = self._bc.find_utxo()
  File "/Users/Documents/Github/blockchain-py/blockchain-py/blockchain.py", line 92, in find_utxo
    for block in self.blocks:
RuntimeError: generator raised StopIteration

那是用来产生Debug断点的，删除那两行就行了。

删除了，还是有点报错。
