We recommend the usage of yarn and if you have multiple packages the usage of yarn workspaces that handles by default hoisting of dependencies:

yarn add @effect-ts/system @effect-ts/tracing-utils @effect-ts/core @effect-ts/jest

To enable the custom matcher equals that uses equals from @effect-ts/core/Structural add @effect-ts/jest/Extend to your Jest setupFilesAfterEnv configuration.

{
  "setupFilesAfterEnv": ["@effect-ts/jest/Extend"]
}

and import import "@effect-ts/jest/Extend" in your global.d.ts or in a valid typeRoot
