请问在对influxdb进行源码编译时，报如下错：
go build github.com/influxdata/flux/libflux/go/libflux:
pkg-config --cflags -- flux
Package flux was not found in the pkg-config search path.
Perhaps you should add the directory containing `flux.pc'
to the PKG_CONFIG_PATH environment variable
No package 'flux' found
pkg-config: exit status 1
可以怎么解决呢
