Question

我在win10上使用Docker Toolbox运行unbuntu：最新的docker容器。我使用create-react-app npm为我自动创建一个react应用程序。当我运行“npm start”时，我收到以下错误。

events.js:182
      throw er; // Unhandled 'error' event
      ^

非常简单的东西 - 这是我的dockerFile

FROM ubuntu:latest

ENV DEBIAN_FRONTEND noninteractive

RUN apt-get update
RUN apt-get install -y apt-utils
RUN apt-get install -y curl
#RUN curl -sL https://deb.nodesource.com/setup_6.x | bash -
RUN curl -sL https://deb.nodesource.com/setup_8.x | bash -
RUN apt-get install -y nodejs

# install editor
RUN apt-get install -y vim

# install tools and create frontend
RUN npm install -g create-react-app
RUN create-react-app frontend

# configure proxy (let's frontend talk to backend)
RUN sed '$i,\n"proxy": "http://localhost:3001"' frontend/package.json >> frontend/package.json.new
RUN cp frontend/package.json.new frontend/package.json

WORKDIR /frontend

# run the frontend
CMD npm start

我可以在我的mac上构建相同的dockerfile，它工作正常。 FSWatch是一个检查文件是否发生变化的库 - 所以不确定这里到底发生了什么。我有点难过。任何帮助将不胜感激。

Docker Toolbox不支持文件系统事件通知。（由Docker dev Mano Marks确认）。需要使用＆＃34; Docker for Windows＆＃34;它的工作原理。

猜猜MSFT正在贬低我。
