I followed the tutorials below for the installation of the tensorflow model:
https://flows.nodered.org/node/node-red-contrib-tf-model
https://github.com/tensorflow/tfjs/blob/master/tfjs-node/WINDOWS_TROUBLESHOOTING.md
Steps taken:
I first installed the #tensorflow/tfjs-node inside Node-RED directly by running the following code:
C:\Users\username\.node-red\node_modules> npm install #tensorflow/tfjs-node#1.4.0
Ran npm install under C:\Users\username\.node-red\node_modules\#tensorflow\tfjs-node:
C:\Users\username\.node-red\node_modules\#tensorflow\tfjs-node> npm install
Finally ran npm install node-red-contrib-tf-model in the same directory:
C:\Users\username\.node-red\node_modules\#tensorflow\tfjs-node> npm install node-red-contrib-tf-model
Error that occured:
npm WARN node-red-contrib-tf-model#0.1.11 requires a peer of #tensorflow/tfjs-node#^1.4.0 but none is installed. You must install peer dependencies yourself.
npm WARN #tensorflow/tfjs-node#1.4.0 No license field.
I have installed the correct tfjs-node version, and so why does this error occur?
Edit: Tried installing the module straight from Node-RED itself and got the following
ERROR:The specified module could not be found.
C:\Users\username\.node-red\node_modules\#tensorflow\tfjs-node\lib\napi-v6\tfjs_binding.node
When I checked the above directory it turns out that I do have the 'tfjs_binding.node'.
What am I doing wrong here? Can someone please help me out.
I was trying to figure out how local cache is fitted in npm install flow. I did the following:
npm cache clear --force
npm cache rd
npm install react#16.10.1
I disconnected from the internet
I removed the node_modules directory
npm install react#16.10.1
The package got installed and a package-lock.json was created successfully; however the following warning in the console made me confused:
Using stale data from https://registry.npmjs.org/ because the host is inaccessible -- are you offline?
npm WARN registry Using stale data from https://registry.npmjs.org/ due to a request error during revalidation.
...
...
Why did npm try to connect to the registry at all while the package does exist in the local cache? and
What was npm trying to get from the registry? Did it try to download the whole package or it just wanted to check some metadata like hash or so?
I'm developing some JavaScript application with VSCode editor, and it says cannot find ESlint package. So i tried install it locally on app directory and globally, but both methods are failed. It gives following error(log file) and stops installation.
silly fetchPackageMetaData error for emoji-regex#^7.0.1 Unexpected end of JSON input while parsing near '...gex-7.0.1.tgz","fileC'
i tried to install package that causes the error and it also get failed, i cleared cache of npm with npm cache clean --force and re-install eslint package. And it worked.
I try to install node_module in my angular project what I downloaded, but I get this error:
npm ERR! registry error parsing json
Then i reinstall npm using npm intall npm -g and after when i try use npm install I get this error:

16 error <https://github.com/npm/npm/issues>
I already tried npm cache clean --force but i get same error.
node -v v6.10.2
npm -v 5.4.2
I had the same issue. I resolved it
by excluding package-lock.json file
npm i --no-package-lock
OR by manually deleting package-lock.json
Run npm cache clean --force and perform an install.
I had the same issue. I resolved it by remove nodejs#10 and install nodejs#8
On Windows 10 running npm install gave me this error.
I solved this issue by doing so from within Administrator: Command Prompt.
Ensure that you have a package.json file within the root of your angular project which should look something similar to this.
https://github.com/heroku/node-js-sample/blob/master/package.json
If the package.json file exists, you run npm install to get the packages saved to it and that will generate a node_modules directory for you.
However, if the file does not exist, it means you have to initialize npm into the project by running npm i -y which should automatically create a package.json file for you and as well allow you to install node modules.
NB: You have npm installed on your machine already so running npm install npm -g is not ideal.
I got this error when my package.json referred to a package using file:../(local path) and the directory didn't exist. Pointing it to the correct path resolved the error.
In my case... none of the above worked. I then deleted my package-lock.json. When I ran an npm install I got an error that a certain package could not be found in the repository. When I removed that from package.json my npm install worked!
I had the same issue. In my case it was caused by a syntax error within the .npmrc file, which was manually edited
Method 1:
npm cache clean --force then install your package
Method 2:
Disable your antivirus software and try to install your package
Method 3:
It is your internet connection, if you are using Wifi or an Ethernet connection use your cellular network or a different network and try to install your package
I am trying to run the project its given following error.
npm start error Failed at the nedben-fe#0.0.1 start script ' grunt
live'.
I tried the following but it did not work
npm i findup-sync --save
