成功使用OSError部署后，Azure功能失败:[Errno 107] [英] Azure function failing after successfull deployment with OSError: [Errno 107]
问题描述
该功能在上次部署之前有效.它用于NLC，我们正在为两种不同的语言运行两个函数.对于新部署，我们删除了一些仅用于一种语言的代码，并将其镜像为与另一种语言相同.Azure CLI告诉我们:
The function was working before the last deployment. It is used for NLC and we are running two functions for two different languages. For the new deployment we removed some code which was only used for one language and mirrored the code to be equal to the other language. Azure CLI tells us:
Upload completed successfully.
Deployment completed successfully.
但是随后尝试调用该函数时，它要么返回没有主体的500，要么返回带有以下内容的404:
But when trying to invoke the function afterwards it either returns 500 without a body or it returns 404 with:
<html>
<head>
<title>404 Not Found</title>
</head>
<body bgcolor="white">
<center>
<h1>404 Not Found</h1>
</center>
<hr>
<center>nginx</center>
</body>
</html>
The stacktrace we can see in the monitoring is the following:
Exception while executing function: Functions.classify Result: Failure
Exception: OSError: [Errno 107] Transport endpoint is not connected: '/home/site/wwwroot/.python_packages/lib/site-packages'

用于部署的命令如下，以前曾工作过:
Commands used for deployment were the following, which worked before:
pip3 install --target="./.python_packages/lib/site-packages" -r requirements.txt
func azure functionapp publish [functionapp name] --no-build
- 删除python包并重建等.
- 我尝试从头开始创建一个新的功能应用程序，但显示出相同的错误.
- 我尝试从另一种语言的文件夹中部署，交换了一个文件(分类器语言模型)，但是它显示相同的错误.我担心尝试重新部署工作语言用于测试，因为它正在工作，我不想杀死它.
推荐答案
似乎在模块导入期间发生.尽管我不确定它以前是如何工作的(如您所述)，但我建议您不要手动进行 pip3安装并删除-no-build标志以使 func azure functionapp发布
It seems to be happening somewhere during module import. Though I am not sure how it was working before (as you mentioned), but I suggest you not to do pip3 install manually and remove --no-build flag to let the func azure functionapp publish handle that. Just make sure you have the requirements.txt in the root.
# no pip install manually
# without --no-build flag
func azure functionapp publish [functionapp name]
