通过curl在ubuntu中安装Google Cloud SDK时出错

运行命令：

curl https://dl.google.com/dl/cloudsdk/release/install_google_cloud_sdk.bash | bash

（我尝试“卷曲https://sdk.cloud.google.com/ | bash”有相同的错误）

没问题...

显然错误发生在“gcloud app Python Extensions”中....

细节：

Python版本是2.7.6
经销商ID：Ubuntu描述：Ubuntu 14.04 LTS版本：14.04代号：trusty
