## Environment Before you follow the instructions below, make sure that `ecc-gulp-tasks` is up to date. You may do that by running `gulp doctor --self-check`. If you are sure, you want to update your environment, you can follow these steps: 1. Find out which node packages are installed globally ```bash npm ls -g --depth 0 yarn global ls ``` 2. Update env ```bash # update nvmrc and node bash -c "echo "6.9.4" > ~/.nvmrc" nvm install # install latest npm and yarn npm install --global npm@<%= npm.version %> yarn@<%= yarn.version %> ``` 3. Reinstall you installed with npm/yarn, for example: ```bash yarn global add gulp eslint ecc-license-checker ```
