Cant create index file on adding to feeds.conf.default

[runalsh]

Added src-git 3proxy https://github.com/osnosn/3proxy-openwrt to feeds.conf.default .
Cannot create index file.
On ./scripts/feeds update -a get error

Create index file './feeds/3proxy.index'
grep: feeds/3proxy/Makefile:$(eval: No such file or directory
grep: $(call: No such file or directory
grep: BuildPackage,3proxy))/Makefile: No such file or directory
/root/openwrt/feeds/3proxy.tmp/info/.files-packageinfo.mk:1: *** target pattern contains no '%'.  Stop.

In file /root/openwrt/feeds/3proxy.tmp/info/.files-packageinfo.mk
$(eval $(call PackageDir,Makefile:$(eval $(call BuildPackage,3proxy)),Makefile:$(eval $(call BuildPackage,3proxy)),))
After run ./scripts/feeds install -a get error
Ignoring feed '3proxy' - index missing

No need to add into feeds.conf.
Just "git clone 3proxy-openwrt" into the "package/" directory.
Read "README.md".
