【问题描述】：

我正在尝试 Dockerise 一个 React 应用程序，但是当它到达安装 npm 的命令时会引发错误。

我的 Dockerfile 包含：

# pull official base image
FROM node:12.6.0-alpine


# set working directory
RUN mkdir /app
COPY . /app
WORKDIR /app
ENV PATH /app/node_modules/.bin:$PATH

RUN yarn

# start app
CMD ["npm", "start"]

当它到达运行npm install或yarn的命令时错误是这样的：

[5/5] RUN yarn:

标签： reactjs docker npm yarn-v2

【解决方案1】：

#9 40.35 error 找不到二进制 git

解决方案：在你的 docker 镜像中安装 git。

【解决方案2】：

像这样在你的镜像中安装 git

FROM node:12.6.0-alpine
RUN apk update && apk add git

# set working directory
RUN mkdir /app
COPY . /app
WORKDIR /app
ENV PATH /app/node_modules/.bin:$PATH

RUN yarn

# start app
CMD ["npm", "start"]

谢谢，它有效。另外，我目前正在研究 React(UI)，每次我在 VS 编辑器上更改代码时，我都需要查看 dom 上的更改，有没有办法让容器监听更改并立即更新图像？ . - 不确定，但可能是音量或类似的东西，这是我的 docker 文件 FROM node:12.6.0-alpine RUN apk update && apk add git # set working directory RUN mkdir /app COPY 。 /app WORKDIR /app ENV PATH /app/node_modules/.bin:$PATH RUN yarn # 启动应用 CMD ["npm", "start"]
