使用Boto3从googleappengin管理AWS

Question

我试图使用Boto3来管理GAE应用程序中的一些EC2实例，但是导入Boto3会导致以下错误：

Traceback (most recent call last):
  File "/Applications/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/google/appengine/runtime/wsgi.py", line 240, in Handle
handler = _config_handle.add_wsgi_middleware(self._LoadHandler())

class Loader(object):
  File "/Users/squad/Desktop/Squad/Squad/lib/botocore/loaders.py", line 201, in Loader
CUSTOMER_DATA_PATH = os.path.join(os.path.expanduser('~'),
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/posixpath.py", line 261, in expanduser
import pwd
  File "/Applications/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/google/appengine/tools/devappserver2/python/sandbox.py", line 963, in load_module
raise ImportError('No module named %s' % fullname)
ImportError: No module named pwd

我可以很好地使用Boto，所以这不是一个迫切的需要，但如果可能的话，我更喜欢使用Boto3。在

我正在使用Python2.7，如果这有帮助的话。在

您必须伪造pwd模块。在

使用必要的垫片创建一个名为fake_pwd.py的文件：

class struct_passwd_dummy(object):

    def __init__(self, uid):
        self.pw_name = "user"
        self.pw_passwd = "x"
        self.pw_uid = uid
        self.pw_gid = uid
        self.pw_gecos = "user"
        self.pw_dir = "/home/user"
        self.pw_shell = "/bin/sh"


def getpwuid(uid):
    return struct_passwd_dummy(uid)

然后，在appengine_config.py中，尝试以下方法：
