为什么 requirements.txt 没有在部署到 AppEngine 时安装？

Question

我正在尝试将现有项目升级到新的 Python 3 AppEngine 标准环境。我能够部署我的应用程序代码，但是该应用程序崩溃了，因为它找不到 requirements.txt 文件中定义的依赖项。应用程序文件结构如下所示：

|____requirements.txt
|____dispatch.yaml
|____dashboard
| |____dashboard.yaml
| |____static
| | |____gen
| | | |____favicon.ico
| | | |____fonts
| | | | |____MaterialIcons-Regular.012cf6a1.woff
| | | |____app.js
| | |____img
| | | |____avatar-06.png
| | | |____avatar-07.png
| | | |____avatar-05.png
| | | |____avatar-04.png
| |____templates
| | |____gen
| | | |____index.html
| |____main.py
| |____.gcloudignore
|____.gcloudignore

requirements.txt 文件如下所示：

Flask==0.12.2
pyjwt==1.6.1
flask-cors==3.0.3
requests==2.19.1
google-auth==1.5.1
pillow==5.3.0
grpcio-tools==1.16.1
google-cloud-storage==1.13.0
google-cloud-firestore==0.30.0
requests-toolbelt==0.8.0
Werkzeug<0.13.0,>=0.12.0
firestore-model>=0.0.2

部署后，当我在网络上访问该站点时，收到 502。GCP 控制台错误报告服务表明错误是从 main.py 中的一行抛出的，它试图导入其中一个以上依赖项：ModuleNotFoundError: No module named 'google'

我尝试将 requirements.txt 移动到仪表板文件夹中并得到相同的结果。

ModuleNotFoundError: No module named 'google'

Answer 1

有些地方可能出了问题。确保：

您的 requirements.txt 文件与您的 main.py 文件位于同一目录中
您的 .gcloudignore 没有忽略您的 requirements.txt 文件
您正在将函数部署在与 requirements.txt 和 main.py

为什么 requirements.txt 没有在部署到 AppEngine 时安装？

Why is requirements.txt not being installed on deployment to AppEngine?

google-app-engine

pip

python-3.x

requirements.txt

google-cloud-platform
