在 Google App Engine's Python runtime for Managed VMS ，我要安装Splinter ( Selenium )Chromedriver。根据 Linux 的文档，我的 dockerfile 中有以下内容:

# Dockerfile extending the generic Python image with application files for a
# single application.
FROM gcr.io/google_appengine/python-compat

RUN apt-get update && apt-get install -y apt-utils zip unzip wget

ADD requirements.txt /app/
RUN pip install -r requirements.txt

RUN cd $HOME/
RUN wget https://chromedriver.googlecode.com/files/chromedriver_linux64_20.0.1133.0.zip
RUN unzip chromedriver_linux64_20.0.1133.0.zip

RUN mkdir -p $HOME/bin
RUN mv chromedriver /bin
ENV PATH "$PATH:$HOME/bin"

ADD . /app

WebDriverException: Message: 'chromedriver' executable needs to be
available in the path. Please look at

最佳答案

您需要查看 ENTRYPOINT和 CMD与该图像相关联(在您启动的容器上执行 docker inspect)

如果图像设置为打开一个新的 bash session ，profile或 .bashrc与运行该 session 的帐户相关联可能会重新定义 $PATH ，覆盖 Dockerfile ENV PATH "$PATH:$HOME/bin"指示。

如果是这种情况，请确保 profile或 .bashrc定义权利 PATH修改 COPY 更容易(例如，使用自定义 .bashrc 的 ENV) .
