Local installation (recommended)
The recommended way of using Buidler is through a local installation in your project. This way your environment will be reproducible and you will avoid future version conflicts. To use it in this way you will need to prepend
npx to run it (i.e.
npx buidler). To install locally initialize your
npm project using
npm init and follow the instructions. Once ready run:
npm install --save-dev @nomiclabs/buidler
Be careful about inconsistent behavior across different projects that use different Buidler versions.
npm install --global @nomiclabs/buidler
If you choose to install Buidler globally, you have to do the same for its plugins and their dependencies.
