我一直在我的Makefile上找几个小时，却找不到“ make build”在这里给我一个错误的原因：
GOBUILD=go build
GOX=gox
BINARY_NAME=tobw
VERSION=$(shell git describe --tags --always --dirty)
# linker flags for stripping debug info and injecting version info
LD_FLAGS="-s -w -X main.Version=$(VERSION)"

# Used for help output

HELP_COLOR=33
HELP_FORMATSTRING="\033[$(HELP_COLOR)m%-$(HELP_SPACING)s \033[00m%s.\n"

结果：
make build
Makefile:26: *** missing separator. Stop.
首先，我认为这是空格与制表符的问题，但我不再认为是这种情况：

我能理解为什么人们一旦不得不处理Makefile，就不能继续从事软件开发事业...
