在Google Cloud Function中访问用户自定义包(ModuleNotFoundError: No module named...)

我正在从源代码库部署Google Cloud函数。只要我在main.py中不引用存储库中的任何用户定义函数（即package或package2中的脚本/函数，除了main.py），就可以成功部署Google Function。

.
├── package
|   ├── __init__.py
|   ├── main.py
|   ├── requirements.txt
|   ├── script1.py
|   └── script2.py
├── package2
|   ├── __init__.py
|   ├── script3.py
|   └── script4.py
└── ...

我有两个最近的Stack Overflow问题与此函数部署相关，分别在这里和这里。它们共同引导我走向一个解决方案，即将main.py和requirements.txt放在一个包中，并将该包作为源来部署Google Cloud Function。现在的问题是，我需要能够访问其他包/脚本中的函数/脚本。如果我在main.py中包含像from package.script1 import foo这样的语句，当我部署函数时会出现下面的错误：

ERROR: (gcloud.functions.deploy) OperationError: code=3, message=Function load error: Code in file main.py can't be loaded.
Did you list all required modules in requirements.txt?

    from package.script1 import foo
ModuleNotFoundError: No module named 'package'

我目前正在使用以下Google函数部署语句来部署此功能：

gcloud functions deploy NAME --source https://source.developers.google.com/projects/PROJECT_ID/repos/REPOSITORY_ID/moveable-aliases/BRANCH_NAME/paths/package/ --trigger-topic TOPIC

将 main.py 和 requirements.txt 移回根目录由于这个stackoverflow问题中的问题而无法正常工作。

我需要一种方法在gcloud functions deploy ...语句期间导入用户定义的软件包/函数。我的main.py使用package.script1.py，package.script2.py，package2.script3.py和package2.script4.py中的函数。如何实现？

编辑/更新的信息

我确实在每个包（package和package2）中都有__init__.py文件，但它们目前是空白的。

我尝试了以下gcloud deploy...选项：

main.py and requirements.txt in the root directory (instead of the configuration as shown above/originally) with this deploy command:

gcloud functions deploy NAME --source https://source.developers.google.com/projects/PROJECT_ID/repos/REPOSITORY_ID/moveable-aliases/BRANCH --trigger-topic TOPIC

This produces the following error:

ERROR: (gcloud.functions.deploy) OperationError: code=3, message=Function load error: File main.py that is expected to define function doesn't exist

In an attempt to explicitly call out the root directory as source, I've also tried this with the same file configuration as in #1

gcloud functions deploy NAME --source https://source.developers.google.com/projects/PROJECT_ID/repos/REPOSITORY_ID/moveable-aliases/BRANCH/paths/ --trigger-topic TOPIC

It gives me the same error as #1:

ERROR: (gcloud.functions.deploy) OperationError: code=3, message=Function load error: File main.py that is expected to define function doesn't exist

The using the original file structure in this question (with main.py and requirements.txt in package), I have tried the deploy statement provided above. It resolves the main.py not found issue, but gives me the error as stated in the original question above

我还应该尝试什么？

你的每个包目录中都有__init__.py文件吗？ - Dustin Ingram

很高兴收到你的来信，达斯汀！是的，我有这些，但它们仍然是空白的。我应该如何填充它们以使其工作？ - Jed

你应该按照以下方式构建你的应用程序：

.
├── main.py
├── package
│   ├── __init__.py
│   ├── script1.py
│   └── script2.py
├── package2
│   ├── __init__.py
│   ├── script3.py
│   └── script4.py
└── requirements.txt

然后在 main.py 中，你可以这样做：

from package.script1 import foo
from package2.script2 import bar
# etc
