python pycrypto: module' object has no attribute 'importKey'

Question

I'm currently working with pycrypto and I want to import public key,but it can not work and raise some error: 'module' object has no attribute 'importKey''
I also use pycrypto in my other script,it works well,so I can not understand why this can not work.
my code that can't work is as following:

    from Crypto.PublicKey import RSA
    .............
    .............
    def task_name(task):
        username = task['user']
        taskintid = task['taskintid']
        data = '%s,%s' % (str(username), str(taskintid))
        user_id = task.get('op_user_id', '')
        db = get_db()

        ssh_key = db.ssh_key.find_one({'user_id': user_id})
        if ssh_key:
            try:
                public_key = RSA.importKey(ssh_key.get('ssh_key', ''))
                data = public_key.encrypt(data, 32)[0].encode('hex')
            except Exception, e:
                print e

    return "task-%s-%s" % (data, task['repeat_num'])

also, my python version is 2.6.5
=======================================
sorry,I forgot it, the pycrypto version is 2.0.1
because I have installed many packages,so I can not upgrage my pycrypto version

Support for exporting and importing RSA keys was implemented in version 2.2 listed in the changelog so unless you can upgrade you are out of luck.
