Hello,
I have an Azure App Service web app running the NODE|18-lts Linux runtime stack.
I'm doing a zip deploy of a node app and my server code ( Remix app server ) evidently uses some syntax that requires npm >= 7 to run.
However, the app service container only seems to use npm 6.14.15, regardless of the node runtime version specified in the config.
The container will utilize the node and npm executables at /usr/local/bin .
The node executable changes versions along with the config, but the npm version stays at 6.14.15.
If I deploy my app using the service as-is, my startup command gives me a cryptic error:
npm start
npm info it worked if it ends with ok
npm info using npm@6.14.15
npm info using node@v18.12.1
npm info lifecycle
Azure App Service

SnehaAgrawal-MSFT 22,706 Reputation points Moderator2023-02-20T12:49:21.4466667+00:00 Christopher Barless Thanks for reaching here! Node.js apps must be deployed with all the required NPM dependencies. The App Service deployment engine automatically runs
npm install --productionfor you when you deploy a Zip package with build automation enabled.To show all supported Node.js versions you may use below command from Azure CLI
az webapp list-runtimes --os linux | grep NODETo set your app to a supported Node.js version, run the following command
az webapp config set --resource-group <resource-group-name> --name <app-name> --linux-fx-version "NODE|14-lts"This setting specifies the Node.js version to use, both at runtime and during automated package restore in Kudu.
Please Note that you should set the Node.js version in your project's package.json
The deployment engine runs in a separate container that contains all the supported Node.js versions.
Please refer to this document on troubleshooting: https://learn.microsoft.com/en-us/azure/app-service/configure-language-nodejs?pivots=platform-linux#troubleshooting
Let us know if further query or issue remains.

2023-02-20T19:03:33.0266667+00:00 Hi Sneha! Thanks for the reply.
Everything you said is working. The Node version is correct.
My problem is that the NPM version is incorrect. Alongside NODE|18-LTS, it's running NPM 6, when I would expect NPM 8 or 9.
My webapp (specifically Remix App Server) will not start on Azure's NODE|18-LTS, which uses NPM 6. But, if I use the SCM bash prompt to install NPM 9 on that same machine, my webapp starts and runs perfectly with no other changes.
Logs after changing the Node version from 16 to 18 in the Azure web app configuration:
2023-02-16T19:04:00.780278838Z npm info using npm@6.14.15The Node version correctly goes from 16 to 18, but the NPM version stays at 6.
I've tested extensively and determined that the outdated NPM is the cause of my issue.
The issue is reproducible by creating any new NODE|{16,18}-LTS web app, and the fix is reproducible by installing the latest version of NPM on that machine.

VanidaB-5672 25 Reputation points2023-03-19T01:15:09.0766667+00:00 I am having the same issue trying to run a very basic remix-run app. After hours, I noticed in the scm's bash, I can not install the required dependencies because my Node is stuck on 10 and npm at 6 :=/ even though in the application setting, I have my node set to 16 LTS.

Im having the same issue. My linux app service is "stuck" on node version 14.19 and I need be at least 16.18 in order for it to work with the latest nextjs 13.4 release.
