Hi, the open source 7.x version has not been released yet, we don't recommend to use 7.x content, we still recommend to use the latest LTS v6.6 branch for compilation; moreover, since compilation environments vary, we provide a mirror specifically for compilation, can you please refer to this link to try it again:
