ModuleNotFoundError: No module named 'aiohttp'

Question

寻找 this existing issue

的解决方法

使用 azure web app(linux) 计划，linux_fx_version 是 Python|3.7

我的requirement.txt是

botbuilder_schema==4.13.0
requests==2.25.0
aiohttp==3.7.4
botbuilder==0.0.1
botbuilder-core==4.13.0
botbuilder-dialogs==4.13.0

当我尝试执行 zip deploy(az webapp deployment source config-zip ) 时，部署进展顺利 - 使用 Kudo zip deploy，除了在启动我的应用程序时它给出错误 liks module not found aiohttp

我尝试了不同版本的 aiohttp ，request 甚至增加了 Python 3.8 目前没有任何效果。

Answer 1

可能是您使用的是 pip 而不是 pip3。 尝试使用 pip3 install -r requirements.txt.

安装依赖项

另一件需要注意的事情是，如果您使用的是 virtual environment，您还需要在其中安装依赖项。

Answer 2

所以有很多事情可以帮助我解决问题。

1. 默认情况下，Kudu 假定 zip 部署不需要任何与构建相关的操作，如 npm install 或 dotnet publish。因此，这种情况下的原因可能是 pip installation 没有得到妥善处理。

   要让它自动安装requirements.txt文件中所有需要的包，我们可以简单地在appsettings中将SCM_DO_BUILD_DURING_DEPLOYMENT设置为true，然后再次部署。

2. 需要设置启动命令如

   gunicorn --bind 0.0.0.0 --worker-class aiohttp.worker.GunicornWebWorker --timeout 600 app:APP
   

3. 正确配置 MicrosoftAppId 和 MicrosoftAppPassword
