c# - Docker 中的剧作家不工作 : Microsoft. Playwright.PlaywrightException:可执行文件不存在

Question

我有一个 .net 仪表板应用程序，用户可以通过 playwright 将当前页面导出为 pdf。这在本地有效，但是，当我在 Docker 中运行应用程序时，出现此错误:

    Microsoft.Playwright.PlaywrightException: Executable doesn't exist at /root/.cache/ms-playwright/chromium-1005/chrome-linux/chrome
     ╔════════════════════════════════════════════════════════════╗

错误来自于我没有正确理解 Docker 阶段。这是一个固定的 Dockerfile，我在基础阶段安装了 Playwright:

FROM mcr.microsoft.com/dotnet/aspnet:6.0 AS base
RUN apt-get update
RUN apt-get -y install curl gnupg
RUN curl -sL https://deb.nodesource.com/setup_16.x  | bash -
RUN apt-get -y install nodejs
RUN npx playwright install
RUN apt-get update && apt-get install -y --no-install-recommends \
