Hi @xushiwei, what's the reason why this mod was downgraded to v0.19.0? I tried to build the fmt package or os package, and got this error message:

panic: Cannot range over: func(yield func(E) bool)

Upgrade x/tools to v0.22 can avoid this problem, although the fmt or os cannot be linked for other reason.
