Webpacker 编译失败 - 错误：[Errno 21] 是目录：'bin'

Question

我刚开始使用 Docker，一切都在进行，直到我尝试访问我的超级基本应用程序的页面。我得到了这个：

web_1    | [Webpacker] Compiling...

这是我第一次看到这个错误。

这是我的 docker-compose.yml

version: '3'                                                                                                                                                                                                                          

services:

  web:
    build: .
    ports:
      - "3000:3000"
    volumes:

这是我的 Dockerfile：

有人遇到过这个错误吗？请帮忙。谢谢！

我遇到了同样的错误。也许你需要安装最新版本的nodejs和yarn。

将此添加到您的 Dockerfile：

（假设你有 curl，如果没有安装它）

RUN curl -sL https://deb.nodesource.com/setup_12.x  | bash -
RUN curl -sS https://dl.yarnpkg.com/debian/pubkey.gpg | apt-key add
RUN echo "deb https://dl.yarnpkg.com/debian/ stable main" | tee /etc/apt/sources.list.d/yarn.list
RUN apt-get update -qq && apt-get install -y nodejs yarn

然后在最后我添加以下内容进行编译：

RUN npm rebuild node-sass #maybe you don't need it, I do
RUN bundle exec rails assets:precompile
