Hi,

I have `X` and `Y` two custom nodes. I installed node `X` and `Y` I used them for a while. Then, I re-install node Y and it removes node `X` and I have to reinstall `X` node. What are the possible reasons for this behavior? Is this due to a dependency conflict between these two nodes?

Regards,  
Malintha

How did you install the nodes?  
How did you re-install node Y?

What version of npm (`npm -v`) are you using?

One possible explanation is your nodes were not listed in `.node-red/package.json` and you are using npm 5 or later. When you reinstalled node Y, npm will have removed node X if it was not listed in your package.json.

I am using `npm 6.5.0 version`.

I install nodes using`npm install <location_of_the_source_folder>` command in side `.node-red` folder.

I can see both nodes are in`.node-red/package.json` file. But After installing Y, the short cut folder of X which was in `.node-red/node_modules` folder is missing and but the registration is still there in the `package.json` file.

In which case, all I can say is you're hitting some odd behaviour of npm - it isn't anything Node-RED is doing.
