在OSX 10.11 Node v4.4.5 NPM 3.9.5上设置Serverless 0.5.6后，我运行serverless project install serverless-graphql-blog并为新配置文件提供IAM凭据，我得到：

当我使用现有的凭据集时，我得到：
/Users/mac/.npm packages/lib/node_modules/servless/node_modules/bluebird/js/release/async.js:61fn=函数()｛throw arg；｝；^ServerlessError:ServerlessError:用户：arn:aws:iam:：…：用户/@gmail.com未被授权在上执行：cloudformation:DescriptionStackResourcesresource:arn:aws:cloudformation:us-west-2:49562908449:stack/serverless-starter-dev-r/*
问题：如何解决安全令牌的问题？有没有一个详细的选项，我可以"；买一个元音"；？
我认为无服务框架正在使用aws-cli配置。您的主路径(/home/xxx/.aws/credentials)上有一个文件，用于存储您的AWS凭据。可能您的凭据没有使用云信息的权限。(Servless广泛使用云信息)cloudformation:DescribeStackResources。
您必须向用户授予权限(添加asws策略)才能对云形成执行操作。
