@susiwen8 zrender also should be switched to next branch and a soft link from local zrender to node_modules/zrender is needed. Mac OS may refer to Wiki: How-to-setup-the-dev-environment Windows may also refer to Wiki: How-to-setup-the-dev-environment, but it needs to pay extra attention to how to create a soft link in Windows.
