Description
Situation: I want to start a blockchain node
Action: sudo python blockchain.py -p 5000
Result:
Traceback (most recent call last):
File "blockchain.py", line 33, in <module>
from urllib.parse import urlparse
ImportError: No module named parse
Attemption:
pip install parse(install success, does not solve problem)
pip install urllib(No matching distribution found for urllib)
pip install urlparse(No matching distribution found for urlparse)
Solution:
In blockchain.py, change
from urllib.parse import urlparse
to
from urlparse import urlparse
Could you please tell me the reason why we cannot import urlparse from urllib.parse?
And I wonder if we can only execute all the command like create node, start the blockchain client under root? As it notify me "cannot import Crypto" when I type python blockchain_client.py without sudo.
Thanks.
