azure - BlobServiceClient 对象没有属性 `exists`

Question

我创建了一个 azure 管道。添加了从 blobStorage 下载文件的任务。

但我收到以下错误:

ERROR: The command failed with an unexpected error. Here is the traceback:

AttributeError: 'BlobServiceClient' object has no attribute 'exists'To open an issue, please run: 'az feedback'
##[error]PowerShell exited with code '1'.\

任务中编写的内联脚本:

az storage blob download-batch --destination $(build.sourcesDirectory) --pattern $(jmxfile) -s $(jmeter-storagecontainer) --account-name $(az-storageaccount) --account-key '$(az-accountkey)' --connection-string '$(az-connstring)'

我已验证所有变量值均正确且 jmxfile 模式也正确。

知道为什么会出现此 BlobServiceClient Object has no attribute 'exists' 错误吗？

Answer 1

如果您使用 az cli 最新版本 并执行，通常会出现错误“BlobServiceClient 对象没有属性‘存在’”>az storage blob download-batch 命令。

• 要解决该错误，请尝试使用 az storage blob download 作为解决方法。
• 否则，请尝试通过卸载 Azure cli 最新版本来安装以前的版本。
• 执行上述步骤时，请确保删除最新版本的所有依赖项。
• 请注意--pattern参数仅支持四种情况

• 请注意，最新 CLI 中存在处理完整 blob 名称的错误。

请查看下面的 GitHub 博客，它证实了上述问题:
