Since Yarn workspace is used, Yarn needs to be installed first: https://yarnpkg.com/en/docs/install#windows-stable
### Windows environment configuration
[The L7 test solution](https://github.com/antvis/L7/blob/master/dev-docs/%E8%87%AA%E5%8A%A8%E5%8C%96%E6%B5%8B%E8%AF%95%E6%96%B9%E6%A1%88.md) relies on headless-gl, which requires node-gyp [to compile local dependencies](https://github.com/nodejs/node-gyp#on-windows).
1. Start PowerShell as an administrator
2. Run `npm install --global --production windows-build-tools` to install Microsoft's windows-build-tools
See [other issues](https://github.com/antvis/L7/issues/101) during installation.
