I am having trouble getting node-red-contrib-opi-gpio to install.  
Platform is NanoPi NEO 2. Connection is via ethernet.  
When I try installing from pallet manager, node install fails with a log that looks like this:  
I cut a bunch of errors out of the middle since I could not fit into post size limit. I assume that once you have gone off the rails and into the next county, more detail isn't usually helpful.

I did have some difficulty with package held messages during the re-install process but I thought I got past them in a way that was ok. I am not clear now on what step I took for that

when I do this:

`npm i node-red-contrib-opi-gpio@0.0.7 `  
or this:  
`npm i node-red-contrib-opi-gpio@0.0.5`

I get this :

```auto
 added 1 package, changed 1 package, and audited 9 packages in 4s
   
   found 0 vulnerabilities

```

which seems ok. Reboot and or restart NR and opi nodes are not available (reloaded browser too) and the pallet manager does not show node-red-contrib-opi-gpio installed. This is what I get from command line:

$ npm list node-red-contrib-opi-gpio  
millheim@1.0.0 /home/millheim  
`-- node-red-contrib-opi-gpio@0.0.7`

**Side note:  
Link in palete manager for node - [node-red-contrib-opi-gpio (node) - Node-RED](https://flows.nodered.org/node/node-red-contrib-opi-gpio) still shows version as 0.0.5 whereas NPM link on that page to view at [npmjs.com](http://npmjs.com) [node-red-contrib-opi-gpio - npm](https://www.npmjs.com/package/node-red-contrib-opi-gpio) shows 0.0.7**

I had node-red-contrib-opi-gpio installed and working but I think some update broke something. I know, not very helpful but at this point I cant remember just when or what and am just trying to re-install all up-to-date (LTS versions preferred) and get working . The gpio is the last bit I need. I have been using 0.0.5 for a year or two just fine but now, I cant get that or the newest to work. I would like to have the ActiveLow pin mode in V0.0.7 but could live without if I must.

Any suggestions?

Did you do the ‘Additional Setup’ described in the node?

Thanks zenofmud. Short answer - yes. I checked that these changes all survived updates. Does something specific in the error logs suggest that I did something wrong in that section of instructions?

It looks as if you are running that from the wrong folder. You should run it from your .node-red folder. Also when installing nodes from the command line you must run the npm command from your .node-red folder.

Thank you Colin. Granting that you are correct, how should I clean up the mess? Is there a mess? This seems an excellent opportunity to leave files etc. laying around in the wrong places that I fall over later...

Delete the `node_modules` folder from where you ran the install previously.  
Also `package.json` and `package-lock.json` from there.

Thanks Colin. I was hoping cleanup would be that straightforward. Using your guidance I was able to get the node up and working in short order. Now for cleanup...
