Checking out master and running demos gives,

bash-3.2$ yarn install
bash-3.2$ yarn compile
bash-3.2$ yarn demos
yarn run v1.15.2
$ yarn ts ./scripts/demos.ts
$ cross-env NODE_ENV=test ts-node -r tsconfig-paths/register -P tsconfig.all.json ./scripts/demos.ts

I'm getting the same error when I run yarn demos :( I tried downgrading some dependencies like typescript and ts-node but no luck.

By the way, I'm on a laptop with Ubuntu 18.04.2 LTS and this is my package.json file:

{ "name": "@haiku/core", "version": "4.5.2", "description": "Haiku Core is a JavaScript library for building user interfaces", "homepage": "https://www.haikuforteams.com", "directories": { "lib": "lib", "dom": "dom", "components": "components", "dist": "dist" }, "keywords": [ "animation", "motion", "component", "web", "browser", "svg", "rendering", "engine" ], "repository": "https://github.com/HaikuTeam/core", "main": "index.js", "scripts": { "lint": "tslint --exclude 'src/vendor/**' -p tsconfig.all.json -t stylish", "lint-report": "yarn lint -t checkstyle -o checkstyle-result.xml", "fix": "yarn lint --fix", "ts": "cross-env NODE_ENV=test ts-node -r tsconfig-paths/register -P tsconfig.all.json", "test": "yarn ts ./node_modules/.bin/tape 'test/**/*.test.ts' | tap-spec", "test-report": "nyc yarn ts ./node_modules/.bin/tape 'test/**/*.test.ts' > test-result.tap", "compile": "tsc", "develop": "tsc --watch", "bundle": "yarn compile && yarn ts ./scripts/bundle.ts", "demos": "yarn ts ./scripts/demos.ts" }, "authors": [ "Matthew Trost <matthew@haiku.ai>", "Zack Brown <zack@haiku.ai>", "Taylor Poe <taylor@haiku.ai>", "Sasha Joseph <sasha@haiku.ai>" ], "license": "MIT", "devDependencies": { "@angular/core": "^6.0.9", "async": "^2.5.0", "chokidar": "^1.7.0", "cross-env": "^5.1.6", "depcheck": "^0.6.7", "express": "4.14.1", "filesize": "3.5.10", "fs-extra": "^4.0.2", "haiku-testing": "4.5.2", "handlebars": "^4.0.8", "istanbul-reporter-cobertura-haiku": "^1.0.2", "jsdom": "^11.1.0", "leaked-handles": "^5.2.0", "nodemon": "1.11.0", "nyc": "^13.0.1", "opn": "^5.3.0", "react": "^16.0.0", "react-dom": "^16.0.0", "react-router-dom": "^4.1.1", "rollup": "^0.53.3", "rollup-plugin-commonjs": "^8.2.6", "rollup-plugin-json": "^2.3.0", "rollup-plugin-node-resolve": "^3.0.0", "rollup-plugin-uglify-es": "^0.0.1", "rxjs": "^6.3.3", "tap-spec": "^4.1.2", "tape": "^4.9.0", "ts-loader": "^4.4.2", "ts-node": "^6.1.0", "tsconfig-paths": "^3.3.2", "tslint": "^5.11.0", "tslint-config-haiku": "^1.0.16", "tslint-no-circular-imports": "^0.5.0", "typescript": "^3.0.3", "webpack": "^4.16.0", "webpack-cli": "^3.0.8" }, "peerDependencies": { "@angular/core": "^6.0.9", "react": "^16.0.0 || ^15.4.2", "react-dom": "^16.0.0 || ^15.4.2" }, "dependencies": { "@haiku/core": "^4.5.2" } }

in the meantime if you want to checkout the demos, you can try running the server manually. This is what I did that might work for you as well:

1. Clone the repository locally.
2. Run yarn install
3. Run yarn add @haiku/core
4. Run node demo/server.js
5. On your browser go to http://localhost:3000/ and you'll see the list of demos.

Important: Make sure to install the @haiku/core (step 3) otherwise the demos won't run and this error will be shown: throw new Error('webpack compile had errors'); . To make sure it is installed check your package.json file, the dependency should be there.
