無法驗證使用libcloud GCE驅動

我試圖使用libcloud（1.3.0）使用下面的代碼連接到我的GCE項目：無法驗證使用libcloud GCE驅動

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)

這只是失敗，內部PyCrypto一個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) 
    File "/usr/lib/python2.7/site-packages/libcloud/compute/drivers/gce.py", line 98, in __init__ 
    credential_file=credential_file, **kwargs) 
    File "/usr/lib/python2.7/site-packages/libcloud/common/google.py", line 765, in __init__ 
    user_id, key, auth_type, credential_file, scopes, **kwargs) 
    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駕駛員頁有關設置服務帳戶，下載JSON文件等等，所以我覺得我做了正確的步驟，但我對所有指令無法擺脫這個問題。

我剛剛在Python 2.7.12上用PyCrypto 2.6.1測試過，並沒有在libcloud 1.3.0上看到任何問題。看着哈希，我懷疑這是你的服務帳戶配置的問題。

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())

從API管理器中，我去了Credentials，然後選擇了「Create Credentials」 - >「Service Account Key」。對於服務帳戶，我選擇了「計算引擎默認服務帳戶」和JSON格式。

Compute Engine的默認服務帳戶

在憑據管理器服務帳戶看起來像這樣
