Hi, everyone. I have some problems with my container.
I have followed the step with [Cannot seem to start Node-RED Docker custom container](https://discourse.nodered.org/t/cannot-seem-to-start-node-red-docker-custom-container/26168) . But in the last step, which he says "The package.json file didn't have "node-red" as a dependency and therefore npm wasn't installing the package.". I didn't know how to add "node-red" into the package.json. Actually, I have add once but it doesn't work. The package.json is below.
package.json
```auto
{
"name": "node-red-project",
"description": "A Node-RED Project",
"version": "0.0.1",
"private": true,
"dependencies": {
"node-red": "1.2.6",
"node-red-contrib-buffer-array": "~1.1.0",
"node-red-contrib-counter": "~0.1.6",
"node-red-contrib-modbus": "~5.13.3",
"node-red-contrib-opc-da": "~1.0.3",
"node-red-contrib-opcda-client": "0.0.5",
"node-red-contrib-opcua": "~0.2.89",
"node-red-contrib-re-postgres": "~0.2.2",
"node-red-contrib-redis": "~1.3.7",
"node-red-dashboard": "~2.25.0",
"node-red-node-mysql": "~0.1.1",
"node-red-node-random": "~0.2.0",
"node-red-node-serialport": "~0.11.1"
}
}
```
Dockerfile
```auto
FROM nodered/node-red:latest
# Copy package.json to the WORKDIR so npm builds all
# of your added nodes modules for Node-RED
COPY package.json /data/
RUN npm install --only=production
# Copy _your_ Node-RED project files into place
# NOTE: This will only work if you DO NOT later mount /data as an external volume.
# If you need to use an external volume for persistence then
# copy your settings and flows files to that volume instead.
COPY settings.js /data/settings.js
COPY flows_nodered.json /data/flows.json
# User configuration directory volume
VOLUME ["/data"]
EXPOSE 1880
CMD ["npm", "start"]
```
After I build the image and run the image. The response is the nodes are missing. That's means the node\_module doesn't work with `npm install `.
Response
```auto
> node-red-docker@1.2.6 start /usr/src/node-red

Your flow credentials file is encrypted using a system-generated key.
If the system-generated key is lost for any reason, your credentials
file will not be recoverable, you will have to delete it and re-enter
your credentials.
You should set your own key using the 'credentialSecret' option in
your settings file. Node-RED will then re-encrypt your credentials
file using your chosen key the next time you deploy a change.

So, how can I add the "node-red" into package.json or how to fix the package.json. Hoping guys can help me to build it successfully. Thanks a lot.
