我有一个通过Shippable部署的Node应用程序。几周前，我的构建开始失败，没有任何环境变化（10/15/19是最后一次成功构建）
我正在部署到Node v 6.11.5，并且在awsebcli安装上失败
CI / CD管道需要AWS Elastic Beanstalk CLI，而当我在不久前进行设置时，我发现我们需要下面的特定版本才能使所有版本都可以与此Node版本一起使用
pip install --force-reinstall awsebcli==3.14.5是失败的行，带有错误
NameError：未定义名称“ platform_system”
我想我只是希望针对其他版本的awsebcli，但我似乎不知道该怎么做
以及完整的错误日志...
Downloading/unpacking docker-compose>=1.21.2,<1.22.0 (from awsebcli==3.14.5)
Downloading/unpacking blessed>=1.9.5 (from awsebcli==3.14.5)
Cleaning up...
