在 google 云 运行 应用程序中为 python selenium 安装 google chrome
Install google chrome for python selenium in a google cloud run app
我正在尝试在我正在开发的云 运行 应用程序中使用 selenium。该应用程序在我的本地计算机上正常运行，但在我将其部署到 google 云 运行 上后无法运行。我收到的错误与未在 google 云上安装 chromedriver.exe 有关。
这是日志中的回溯错误：

Please see https://sites.google.com/a/chromium.org/chromedriver/home
该回溯的相关部分似乎是 Message: 'chromedriver' executable needs to be in PATH。我如何在这个 google 云 运行 应用程序的 PATH 中获取 chromedriver 可执行文件？
现在，我尝试过做什么？
首先，我找到了这个 post: unable to run selenium chrome-driver on google-cloud-run and followed the instructions left in the comments. I looked at this post on dev.to 并按照建议的方式对我的 Dockerfile 进行了建模。唯一的区别是我使用 Python3.6 而不是 Python3.7:
# Use the official lightweight Python image.
# https://hub.docker.com/_/python
FROM python:3.6-slim
# Install manually all the missing libraries
RUN apt-get update
RUN apt-get install -y gconf-service libasound2 libatk1.0-0 libcairo2 libcups2 libfontconfig1 libgdk-pixbuf2.0-0 libgtk-3-0 libnspr4 libpango-1.0-0 libxss1 fonts-liberation libappindicator1 libnss3 lsb-release xdg-utils

# Run the web service on container startup. Here we use the gunicorn
# webserver, with one worker process and 8 threads.
# For environments with multiple CPU cores, increase the number of workers
# to be equal to the cores available.
CMD exec gunicorn --bind :$PORT --workers 1 --threads 8 main:app
我还在 requirements.txt 文件中添加了 chromedriver-binary==77.0.3865.40.0。
当我尝试使用 gcloud builds submit 部署它时，出现此错误：
/bin/sh: 1: wget: not found
The command '/bin/sh -c wget https://dl.google.com/linux/direct/google-chrome-stable_current_amd64.deb' returned a non-zero code: 127
ERROR
ERROR: build step 0 "gcr.io/cloud-builders/docker" failed: step exited with non-zero status: 127
我一直在尝试在线寻找此错误的解决方案，但我迷路了。非常感谢您的帮助！
添加安装命令wget。
