git clone \
  https://github.com/input-output-hk/cardano-js-sdk.git \
  && cd cardano-js-sdk

nvm install && \
nvm use && \
DETECT_CHROMEDRIVER_VERSION=true yarn global add chromedriver && \
yarn install && \
yarn build

The web extension e2e tests uses chromedriver. chromedriver and your Chrome browser versions should match, if they don’t the driver will error. If you have issues, try running yarn workspace @cardano-sdk/e2e remove chromedriver && yarn workspace @cardano-sdk/e2e add chromedriver to reinstall the latest version.
