python - 可执行文件在路径中，但 selenium 在 docker frolvlad/alpine-python3 中找不到

Question

我正在尝试在高山码头运行 selenium。我已经管理了它，FROM python:3但是节省磁盘空间会很好。

我收到错误消息
selenium.common.exceptions.WebDriverException: Message: 'geckodriver' executable needs to be in PATH.
，FileNotFoundError: [Errno 2] No such file or directory: 'geckodriver'
谷歌搜索只会给出“将 geckodriver 放入您的 $PATH”和“使用 PATH=$PATH:/usr/src/app 将 geckodriver 的文件夹路径添加到 $PATH”

但是geckodriver在 $PATH 中，它仍然会导致相同的错误。

我还尝试将可执行文件作为参数添加到，driver = webdriver.Firefox()但它没有任何改变。

Dockerfile：

FROM frolvlad/alpine-python3
WORKDIR /usr/src/app
COPY . .
RUN tar -xzf geckodriver-v0.26.tar.gz && cp geckodriver /bin

RUN pip install --no-cache-dir -r requirements.txt
RUN apk add --no-cache firefox-esr xvfb
ENV DISPLAY=:1.0

ENTRYPOINT ["./entrypoint.sh"]

入口点.sh

Xvfb :1 -screen 0 1024x768x16 &> xvfb.log &
python ./seleniumTest.py

输出：
