无法验证使用libcloud GCE驱动

我试图使用libcloud（1.3.0）使用下面的代码连接到我的GCE项目：无法验证使用libcloud GCE驱动

from libcloud.compute.types import Provider 
from libcloud.compute.providers import get_driver 

USER_ID = "[email protected]" 
KEYFILE = "./xxxxxxx.json" 
PROJECT = "project1" 

cls = get_driver(Provider.GCE) 
driver = cls(USER_ID, KEYFILE, project = PROJECT)

这只是失败，内部PyCrypto一个AttributeError（I” m跑V2.6.1）：

Traceback (most recent call last): 
    File "g.py", line 9, in <module> 
    driver = cls(USER_ID, KEYFILE, project = PROJECT) 
    File "/usr/lib/python2.7/site-packages/libcloud/compute/drivers/gce.py", line 1348, in __init__ 
    super(GCENodeDriver, self).__init__(user_id, key, **kwargs) 
    File "/usr/lib/python2.7/site-packages/libcloud/common/base.py", line 1179, in __init__ 
    self.connection = self.connectionCls(*args, **conn_kwargs)

    credential_file=credential_file, **kwargs) 
    File "/usr/lib/python2.7/site-packages/libcloud/common/google.py", line 765, in __init__

    File "/usr/lib/python2.7/site-packages/libcloud/common/google.py", line 660, in __init__ 
    self.token = self.oauth2_conn.get_new_token() 
    File "/usr/lib/python2.7/site-packages/libcloud/common/google.py", line 530, in get_new_token 
    signature = base64.urlsafe_b64encode(signer.sign(hash_func)) 
    File "/usr/lib/python2.7/site-packages/Crypto/Signature/PKCS1_v1_5.py", line 110, in sign 
    em = EMSA_PKCS1_V1_5_ENCODE(mhash, k) 
    File "/usr/lib/python2.7/site-packages/Crypto/Signature/PKCS1_v1_5.py", line 211, in EMSA_PKCS1_V1_5_ENCODE 
    digestAlgo = DerSequence([hash.oid, DerNull().encode()]) 
AttributeError: oid

我跟着libcloud GCE驾驶员页有关设置服务帐户，下载JSON文件等等，所以我觉得我做了正确的步骤，但我对所有指令无法摆脱这个问题。

我刚刚在Python 2.7.12上用PyCrypto 2.6.1测试过，并没有在libcloud 1.3.0上看到任何问题。看着哈希，我怀疑这是你的服务帐户配置的问题。

from libcloud.compute.types import Provider 
from libcloud.compute.providers import get_driver 

USER_ID = "[email protected]" 
KEYFILE = "./libcloud-test-xxx.json" 
PROJECT = "libcloud-test" 

cls = get_driver(Provider.GCE) 
driver = cls(USER_ID, KEYFILE, project = PROJECT) 
print(driver.auth_type) # should be SA 
print(driver.list_nodes())

从API管理器中，我去了Credentials，然后选择了“Create Credentials” - >“Service Account Key”。对于服务帐户，我选择了“计算引擎默认服务帐户”和JSON格式。

Compute Engine的默认服务帐户

在凭据管理器服务帐户看起来像这样
