Unable to install BigCommerce Stencil CLI with NPM

Question

I'm trying to install the BigCommerce Stencil Cli using NPM. I followed the instructions on the bigcommerce website but when I try to install the Stencil CLI I get errors.

I'm not experienced with NPM, all I want to do it add a style.css file to a bigcommerce theme and they are forcing you to use NPM. Clearly it isn't working for me. Can anyone help me before the voices in my head win, and i put my laptop in the dishwasher.

NPM VERSION:

{
  npm: '8.10.0',
  node: '14.19.3',
  v8: '8.4.371.23-node.87',
  uv: '1.42.0',
  zlib: '1.2.11',
  brotli: '1.0.9',
  ares: '1.18.1',
  modules: '83',
  nghttp2: '1.42.0',
  napi: '8',
  llhttp: '2.1.4',
  openssl: '1.1.1o',
  cldr: '40.0',
  icu: '70.1',
  tz: '2021a3',
  unicode: '14.0'
}

I've tried to uninstall/install npm but I don't really understand what to do here.

Answer 1

I solved this on Mac by using Node v14.20 as advised in the documentation but switching from NPM v7 to NPM v6, this is not mentioned in the documentation.

Assuming you have NVM installed, I did the following:

nvm install 14.20
nvm use 14.20
npm install -g npm@6.14.17 (or the last v6)
npm install -g @bigcommerce/stencil-cli

This now successfuly installs.

Answer 2

I also faced the same problem but found this . You just have to use node version 14.20.0.
