我正在尝试使用本地dev_appserver本地连接到BigQuery API，遵循本教程：<a href="https://developers.google.com/bigquery/authorization?hl=de#service-accounts" rel="nofollow">https://developers.google.com/bigquery/authorization?hl=de#service-accounts</a> 运行此网站上提到的代码，返回一个重要错误： <pre><code>ImportError: cannot import name SignedJwtAssertionCredentials </code></pre> 所以我跟踪错误并发现（在oauth2client/client.py中）： <pre><code>if HAS_CRYPTO: # PyOpenSSL and PyCrypto are not prerequisites for oauth2client, so if it is # missing then don't create the SignedJwtAssertionCredentials or the # verify_id_token() method. class SignedJwtAssertionCredentials(AssertionCredentials): </code></pre> 但我需要“签名的jwtassertioncredentials”！所以我进一步隔离了这个错误，发现（在oauth2client/crypt.py中）这一行实际上导致了这个问题： <pre><code>from OpenSSL import crypto </code></pre> 我试过： <pre><code>$ python >>> import OpenSSL >>> OpenSSL.__file__ '/usr/local/lib/python2.7/site-packages/OpenSSL/__init__.pyc' >>> from OpenSSL import crypto >>> crypto.__file__ '/usr/local/lib/python2.7/site-packages/OpenSSL/crypto.so' </code></pre> 它看起来很有前途，还检查了代码的sys.path： <pre><code>['/Users/mattes/Developer/gae-projects/project123', '/Applications/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine', '/Applications/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine', '/usr/local/Cellar/python/2.7.6/Frameworks/Python.framework/Versions/2.7/lib/python2.7', '/usr/local/Cellar/python/2.7.6/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-dynload', '/Applications/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/lib/webapp2-2.5.2', '/Applications/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/lib/protorpc-1.0', '/Applications/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/lib/webob-1.1.1', '/Applications/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/lib/yaml-3.10'] </code></pre> 无论如何，将<code>"/usr/local/lib/python2.7/site-packages/OpenSSL"</code>添加到sys.path或<code>/Users/mattes/Developer/gae-projects/project123</code>下的符号链接<code>/usr/local/lib/python2.7/site-packages/OpenSSL</code>都无法解决此问题。 <code>/usr/local/lib/python2.7/site-packages/OpenSSL</code>看起来像： <pre><code>├── SSL.so ├── __init__.py ├── __init__.pyc ├── crypto.so ├── rand.so ├── test │ ├── __init__.py │ ├── __init__.pyc │ ├── test_crypto.py │ ├── test_crypto.pyc │ ├── test_rand.py │ ├── test_rand.pyc │ ├── test_ssl.py │ ├── test_ssl.pyc │ ├── util.py │ └── util.pyc ├── tsafe.py ├── tsafe.pyc ├── version.py └── version.pyc </code></pre> 使用Mac 10.9 Mavericks，Python 2.7.5 有人能帮忙吗？
