[英]Python 2.6 — paramiko import error
我有一些在cron
中每30分钟运行一次的脚本,这些脚本会导入paramiko
。 似乎是随机的,导入期间会出现以下两个错误之一:
Traceback (most recent call last):
...
File "build/bdist.linux-x86_64/egg/paramiko/__init__.py", line 65, in <module>
File "build/bdist.linux-x86_64/egg/paramiko/transport.py", line 42, in <module>
File "build/bdist.linux-x86_64/egg/paramiko/packet.py", line 39, in <module>

File "build/bdist.linux-x86_64/egg/Crypto/Util/strxor.py", line 6, in __bootstrap__
ImportError: dynamic module does not define init function (initstrxor)
- 要么 -
Traceback (most recent call last):
...

ImportError: dynamic module does not define init function (init_ARC4)
每当我看到此问题时,只需重新运行脚本即可使paramiko
正确导入并完成脚本。
什么会导致此问题? 任何帮助是极大的赞赏。
虽然我不知道是什么引起了该错误,但似乎在pycrypto的本机部分上还是失败了,因此您可能要重试几次:
from time import sleep
n_tries= 3
import_success= False
while not import_success:
try:
from Crypto.Cipher import Blowfish, AES, DES3, ARC4
from Crypto.Hash import MD5, SHA, SHA256, HMAC
from Crypto import Random
from Crypto.PublicKey import DSA, RSA
from Crypto.Util import Counter, number
import_success= True
except ImportError:
if not n_tries:
raise #re-raise ImportError
n_tries-=1
sleep(1)
