[SOLVED] error could not determine Node.js install directory

error could not determine Node.js install directory

I have tried to install ionic by doing npm install ionic

ionic start myapp blank does not work and since then any npm commands tells me :

$ npm config
node:internal/modules/cjs/loader:927
  throw err;
  ^

Error: Cannot find module 'C:\Users\dandonneau.m\devc\node_modules\npm\bin\npm-cli.js'
    at Function.Module._resolveFilename (node:internal/modules/cjs/loader:924:15)

Could not determine Node.js install directory

Solution

I had the same error because I was using a too new version of Node for my system.

I have Windows 7.
The last officially tested version of Node on Windows 7 is 13.6.0 (source). Although, you can also try to run newer versions such as 15.8.0 (source).
The bug occurred when I tried to use Node version 17.1.0.

Solution

I solved the problem by downgrading the Node version to 15.8.0 (in my case via nvm, you can just re-install).
You can also try upgrading your operating system.
