缺少对Python Azure函数的依赖 [英] Missing Dependencies on Python Azure Function

问题描述

请注意:这在本地可正常使用，但仅在使用天蓝色在线功能时会出现问题.

Please note: This works fine locally but only makes an issue when working on azure online function.

错误:

Result: Failure
Exception: ModuleNotFoundError: No module named 'pandas'

我尝试过的操作:az帐户清除&az登录.如果我写: func azure functionapp发布空气温度

What I have tried : az account clear & az login. If i write : func azure functionapp publish air-temperature

这将导致错误:还原依赖项时出错.错误:无法安装cryptography-2.8依赖项:不支持没有轮子的二进制依赖项.使用"--build remote"或"--build-native-deps"选项可使用Docker容器自动构建和配置依赖项.有关更多信息，请访问https://aka.ms/func-python-publish

我没有使用docker集成，所以我无法执行--build-native-deps

I am not using docker integration so i cant do the --build-native-deps

我正在使用azure信息库将其推送到azure仓库中，并且它的构建似乎没有依赖性或任何错误.但是，如果我通过门户网站在线运行它，则会出现此错误，如顶部所述.

I am using azure repositories to push it into the azure repo and it is build seemlessly without errors on dependencies or anything. But if i run it online through portal it give this error as mentioned at the top.

我还尝试在python上使用venv和env并进行pip冻结> requirements.txt.

I have also tried using the venv and env on python and did pip freeze > requirements.txt.

推荐答案

您可以使用这是 解释 .

在使用--build-native-deps进行一般发布期间，我们尝试使用pyinstaller捆绑您在您指定的所有自定义依赖项Requirements.txt和我们的跑步者(工人)一起.我们开始做这是为了提高您获得的启动性能发布到Azure Functions.虽然，这个过程很不稳定并且我们正计划远离它.

during a general publish using --build-native-deps, we try to use Pyinstaller to bundle all the custom dependencies specified in your requirements.txt together with our runner (worker). We started to do this in an effort to improve startup performance that you get after publishing to Azure Functions. Although, this process has been flaky and we are planning on moving away from it.

-无捆绑程序标志绕过该捆绑过程.因此，我们不使用Pyinstaller或任何此类模块进行临时优化.这请注意，您可能会遇到轻微的延迟(冷启动)到达API终点时.

--no-bundler flag bypasses that bundling process. So, we do not use Pyinstaller or any such module to do temporary optimizations. The caveat is that you may experience slight linger delay (cold start) when hitting your API end-point.
