Azure Function 部署失敗：`上傳構建內容時 SCM_RUN_FROM_PACKAGE 格式錯誤。`

Question

嘗試使用VS 代碼 Azure 函數擴展部署 python 運行時 ( v3.6.9 ) Azure function。

我創建了 function 就好了，然后......

1. 從擴展點擊Upload
2. Create new function app in Azure (advanced)
3. 輸入了一個全球唯一的 function 名稱
4. 選擇Python 3.6作為運行時
5. 選定Consumption托管計划
6. 選擇了現有資源組（僅為該項目創建）
7. 選擇了一個現有的存儲帳戶（僅為該項目創建）
8. 為 App Insights 選擇Skip for now
9. Output window 顯示“正在創建新的 function 應用程序”

...但過程錯誤：

我也試過...

• 右鍵單擊 Function 項目
• Deploy to Azure

……同樣的結果。

EDIT1：還嘗試按照@hury-shen 的建議從 cli 執行遠程構建：

(.venv) user@system:~/Documents/azureBlobToS3$ func azure functionapp publish azureblobtoawss3 --build remote

Getting site publishing info...
Remote build is a new feature added to function apps.
Your function app azureblobtoawss3 does not support remote build as it was created before August 1st, 2019.
Please use '--build local' or '--build-native-deps'.
For more information, please visit https://aka.ms/remotebuild

然后我繼續使用az functionapp update -g <RESOURCE_GROUP_NAME> -n <APP_NAME>更新應用程序。 結果相同。

我還添加了此處列出的應用程序設置，以在 Linux 上啟用遠程構建。 結果相同。

然后我嘗試運行func azure functionapp publish <APP_NAME> --build local並得到錯誤：

There was an error restoring dependencies.   Could not find a version that satisfies the requirement pkg-resources (from -r /home/user/Documents/azureBlobToS3/requirements.txt (line 19)) (from versions: )
No matching distribution found for pkg-resources (from -r /home/user/Documents/azureBlobToS3/requirements.txt (line 19))
ERROR: ['/home/user/Documents/azureBlobToS3/.venv/bin/python3', '-m', 'pip', 'download', '-r', '/home/user/Documents/azureBlobToS3/requirements.txt', '--dest', '/tmp/azureworkerjv2xkb_k'] failed with exit code 1

然而 pip 顯示滿足pkg-resources依賴關系！

(.venv) user@system:~/Documents/azureBlobToS3$ pip install pkg-resources

Requirement already satisfied: pkg-resources in ./.venv/lib/python3.6/site-packages

EDIT2：從requirements.txt中刪除pkg-resources只是為了測試

我在這里陷入了一個循環。 無法遠程構建，無法在本地構建。

There was an error restoring dependencies. ERROR: cannot install cryptography-2.9.2 dependency: binary dependencies without wheels are not supported when building locally. Use the "--build remote" option to build dependencies on the Azure Functions build server, or "--build-native-deps" option to automatically build and configure the dependencies using a Docker container. More information at https://aka.ms/func-python-publish

有沒有其他人看到這個錯誤？ 如何進行故障排除？

Answer 1

Deploy the python function by extension often occurs some problem, so I suggest you to use command to deploy the python function from local to azure. 請參考以下步驟：

1. Go 到 azure 門戶並創建 function 應用程序（python）。

2.單擊 VS 代碼中的“終端”按鈕打開“終端”window 並運行以下命令生成“requirements.txt”，其中包括安裝在 function 中的所有模塊。

pip freeze > requirements.txt

3.運行以下命令，將 function 從本地部署到 azure：

func azure functionapp publish <functionAppName> --build remote

<functionAppName>是您剛剛創建的 function 應用程序的名稱。 運行此命令后，function 代碼將從本地部署到 azure 和 azure 將安裝我們生成的“requirements.txt”內容的模塊

希望有幫助~

Answer 2

我遇到了這些完全相同的錯誤，包括編輯，並按照所有推薦的步驟來解決。 我的問題出在 VSCode 中，我使用 Python 3.7 構建，即使安裝了 3.6。 卸載 Python 3.7 並強制 3.6 構建解決了我的問題。

Answer 3

就我而言，這是因為 Function 應用程序無法訪問存儲帳戶。 我修改了存儲在AzureWebJobsStorage和AZURE_STORAGE_CONNECTION_STRING appSettings 中的連接字符串。

為了確定這一點，我在本地構建了 function 應用程序並嘗試部署。

func azure functionapp publish func-durableFuncAci-ussc-demo --build local --build-native-deps

我收到以下錯誤，告訴我 Function 應用程序的配置有錯誤。

Error creating a Blob container reference. Please make sure your connection string in "AzureWebJobsStorage" is valid
