Python 如何通过boto3获得AWS的配额？

我正在为AWS开发boto3-SDK python

我从ec2的简单服务配额开始，但最后总是出现以下错误

import boto3

quota_client = boto3.client('service-quotas')
response = quota_client.get_service_quota(
ServiceCode='ec2'
)

错误：

quotas'. Valid service names are: acm, acm-pca, alexaforbusiness,

文档页面显示boto3支持服务配额，但看起来不是，或者我在这里做了什么不正确的事情

我可以用当前的

boto3-1.9.174 botocore-1.12.174安装重现问题

然后我做了：

pip install boto3 --upgrade

它将我移动到版本
boto3-1.9.208 botocore-1.12.208
，并且工作正常

我尝试使用Python虚拟环境隔离库，以便于更新。
这对我很有用。您是否尝试过更新您的
bot3
模块？是的，我已更新模块，当前版本为1.9.207。这是正确的版本吗？我的版本是1.9.190。很可能这些版本在某个地方发生了冲突。你也可以尝试降级。谢谢约翰，尝试了同样的方法，现在效果很好
