执行 backup-push 命令时出现以下错误：

# envdir /etc/wal-e.d/env wal-e backup-push /var/lib/postgresql/9.5/main

 wal_e.main   INFO     MSG: starting WAL-E

    During handling of the above exception, another exception occurred:

我已经尝试过更新的 Python 和 Azure

wal-e 版本：1.0.3 SO：Ubuntu Server 16.4.1 LTS

任何的想法？

我尝试成功重现您的问题，并查看了wal-e版本的源代码1.0.3，然后我发现问题是由于wal-e版本1.0.3实际需要的azure-storage版本低于，但是在您通过安装时0.20.3安装了最新azure-storage版本。请检查您当前的via版本。0.34.3pip3 install wal-e[azure]azure-storagepip3 freeze | grep azure-storage

因此，有两种解决方案可以解决该问题，如下所示。

  1. azure-storage将版本降级为0.20.3via pip3 install azure-storage==0.20.3。
  2. 或者只是将需要最新版本的wal-e版本升级到与旧版本兼容，通过.1.1.0b1azure-storagepip3 install wal-e==1.1.0b1

希望能帮助到你。
