When running pnpm install, pnpm throws an error:

$ pnpm install
 ERR_PNPM_BAD_PM_VERSION  This project is configured to use v8.15.6 of pnpm. Your current pnpm is v9.1.1

If you want to bypass this version check, you can set the "package-manager-strict" configuration to "false" or set the "COREPACK_ENABLE_STRICT" environment variable to "0"

The error is not clear what “configuration” should i choose. package.json‘s config field? Or pnpm config? I’m not sure.

From this PR, apparently you need to set it on .npmrc:

package-manager-strict=false

Upgrading the PNPM

Use corepack up, as mentioned by edvinv.

corepack up

… or maybe follow the pnpm’s announcement:

corepack prepare [email protected] --activate

# and update the field:
corepack use [email protected]
