下载 release-v1.4.0在go1.13.8环境编译

# make 
build github.com/bfenetworks/bfe: cannot load io/fs: malformed module path "io/fs": missing dot in first path element
go get golang.org/x/tools/cmd/goyacc
cd "bfe_basic/condition/parser" && go generate
go test -race -cover ./...
build github.com/bfenetworks/bfe: cannot load io/fs: malformed module path "io/fs": missing dot in first path element
Makefile:75: recipe for target 'test-case' failed
make: *** [test-case] Error 1

google发现 https://github.com/DefectDojo/godojo/issues/31

Also, io/fs came into go around 1.16 so if your go version is less than 1.16, that's likely your problem.

感谢反馈的问题！可以使用golang 1.16+版本来编译bfe
