我正在尝试使用以下命令构建docker镜像：
$ docker build --tag us.gcr.io/my_project_id/useradmin-global:20170907 .
我收到此错误：

看看错误，似乎抱怨我的pyasn1安装版本不满意，期望0.3.4。但是，你可以看到它在0.3.4，所以我不知道该怎么做。
我尝试将docker升级到最新版本：
$ docker --version
Docker version 17.06.2-ce, build cec0b72
现在是哪个。还尝试自己运行pip命令，该命令成功：
$ pip install google-api-python-client

感谢任何帮助。
