python - 更新失败，错误代码为 BUILD_DOCKER_UNKNOWN

Question

我正在使用 VS Code 和 Cloud Code 扩展来尝试将 Python 脚本部署到 GCP Cloud Run。我可以使用 Cloud Run 模拟器在本地运行“hello, world”python Flask 应用程序，也可以将其移动以成功部署到 Cloud Run，但当我尝试通过要求添加任何外部库时。 txt 文件并导入到 app.py 文件中，我收到以下构建失败错误消息:

Update failed with error code BUILD_DOCKER_UNKNOWN

app.py 文件:

"""
A sample Hello World server.
"""
import os

from flask import Flask, render_template
import pandas as pd

# pylint: disable=C0103
app = Flask(__name__)


@app.route('/')
def hello():
    """Return a friendly HTTP greeting."""
    message = "It's running!"

    """Get Cloud Run environment variables."""
    service = os.environ.get('K_SERVICE', 'Unknown service')
    revision = os.environ.get('K_REVISION', 'Unknown revision')

    return render_template('index.html',
        message=message,
        Service=service,
        Revision=revision)

if __name__ == '__main__':
    server_port = os.environ.get('PORT', '8080')
    app.run(debug=False, port=server_port, host='0.0.0.0')

需求.txt

Flask==2.2.2
requests==2.28.1
ptvsd==4.3.2 # Required for debugging.
pandas==1.5.0

Dockerfile:

# Python image to use.
FROM python:3.10-alpine

# Set the working directory to /app
WORKDIR /app

# copy the requirements file used for dependencies
COPY requirements.txt .

# Install any needed packages specified in requirements.txt
RUN pip install --trusted-host pypi.python.org -r requirements.txt

# Copy the rest of the working directory contents into the container at /app
COPY . .

# Run app.py when the container launches
ENTRYPOINT ["python", "app.py"]

这不是我应该添加库依赖项的方式吗？请让我知道我还能提供什么来帮助解决此问题。

调试 Cloud Run 的提示:在“输出”面板中，有一个名为 Cloud Run:本地运行/调试 - 详细 的单独 channel 。这包括来自关联 Skaffold 和 Docker 子进程的更详细的日志记录。

当我尝试重现您遵循的步骤(安装 Python Flask Hello World 示例，添加对 pandas 1.5.0 的依赖项)时，我能够看到所添加包的传递依赖项的一些依赖项编译问题，也许您运行了进入类似的东西。
