Docker错误:没有这样的文件或目录，请打开'/package.json' [英] Docker error: no such file or directory, open '/package.json'

问题描述

我正在尝试在docker内部运行节点图像，但出现此错误:

I'm trying to run a node image inside docker but I have this error:

npm WARN saveError ENOENT: no such file or directory, open '/package.json'
npm notice created a lockfile as package-lock.json. You should commit this file.
npm WARN enoent ENOENT: no such file or directory, open '/package.json'
npm WARN !invalid#2 No description
npm WARN !invalid#2 No repository field.
npm WARN !invalid#2 No README data
npm WARN !invalid#2 No license field.

这是我的docker文件.我想将所有项目文件放在容器的/home/app/文件夹中:

Here is my docker file. I want to put all my project files in /home/app/ folder in the container:

# Use an official node runtime as a parent image
FROM node:10

# Set the working directory to /home/app
#WORKDIR /home/app/

# Bundle app source
COPY . /home/app/

# If you are building your code for production
# RUN npm install --only=production
RUN npm install

# Make port 8000 available to the world outside this container
EXPOSE 8000

CMD npm run dev

我在Windows上，并且使用hyper-V.我的package.json与我的Dockerfile处于同一级别.

I'm on windows and I use hyper-V. My package.json is at the same level as my Dockerfile.

有什么想法吗?

谢谢

推荐答案

运行 npm install 命令时，工作目录可能是/，并且没有 package.json 在这里.

When npm install command is run, the working directory is probably /, and there is no package.json here.

只需在 Dockerfile 中取消对 WORKDIR/home/app/行的注释.

Just uncomment your line WORKDIR /home/app/ in your Dockerfile.
