问题似乎来自我的

requirements.txt

文件：

当我部署这个示例时，它运行良好
当我用我的文件替换原来的
```

```
文件时，它不起作用*

这是我的

您是否尝试像这样在本地使用此requirements.txt文件

pip install -r requirements.txt

您的requirements.txt文件的最后两行似乎与可随pip安装的Python包不对应。

您是否尝试在本地像这样使用此requirements.txt文件？：

pip install -r requirements.txt

看起来requirements.txt文件的最后两行与可随pip一起安装的Python软件包不对应。

事实上，

requirements.txt

文件中同时存在

os

和

openfoodfacts

（只需要包含pip可安装的软件包，请参阅）正在导致pip安装错误：

[venv] openfoodfacts> pip install os
Collecting os
  Could not find a version that satisfies the requirement os (from versions: )
No matching distribution found for os

[venv] openfoodfacts> pip install openfoodfacts
Collecting openfoodfacts
  Could not find a version that satisfies the requirement openfoodfacts (from versions: )
No matching distribution found for openfoodfacts

您不需要将

os

添加到您的需求中，它是标准python安装的一部分，您只需导入它即可

而且

openfoodfacts

似乎不是常规的

Pypi

包。如果它来自不需要SSH密钥的pip存储库，您可以在

requirements.txt

文件中指定它，请参阅。否则，您需要将其安装到应用程序中，以便与应用程序代码一起上载，请查看部分

您可以/应该始终尝试检查

requirements.txt

文件的完整性。请注意需要SSH密钥的pip回购，因为默认情况下，您可以通过帐户配置访问这些密钥。

根据您收到的错误，Cloud Build未能安装requirements.txt文件中指定的最后两个依赖项。如果转到并检查失败的部署，您将注意到部署失败，并显示与此类似的错误消息：

Step #1 - "builder": INFO     `pip_download_wheels` had stderr output:
Step #1 - "builder":   Could not find a version that satisfies the requirement openfoodfacts==0.1.0 (from -r requirements.txt (line 10)) (from versions: )

无需在requirements.txt中包含，因为它是Python 3.7标准库的一部分。例如，请注意，基于的应用程序将导入，而这并没有在上指定

实际上尚未在PyPI上发布（即is 404），因此您需要参考的相关部分并手动添加，方式与此类似：

在应用程序的项目目录上创建一个

lib

目录（例如，使用

mkdir lib

创建my）

通过发出以下命令将所需的依赖项复制到新创建的

lib

pip3 install git+git://github.com/openfoodfacts/openfoodfacts-python.git -t lib

转到

lib

目录，验证是否已正确安装所有依赖项

修改

requirements.txt

文件以使用Open Food Facts包所需的依赖项。应该是这样的：

以与导入库类似的方式导入应用程序中的模块。openfoodfacts作为openff

使用

gcloud app deploy

命令部署应用程序

最后，您应该有一个文件结构与此类似的项目目录：

Step #1 - "builder": INFO     `pip_download_wheels` had stderr output:
Step #1 - "builder":   Could not find a version that satisfies the requirement openfoodfacts==0.1.0 (from -r requirements.txt (line 10)) (from versions: )

            __init__.py
            openbeautyfacts.py

文件上的

os
