Can't locate IO/Compress/Lzma.pm
解决：
执行下面命令装一下就行了
sudo cpan -I IO::Compress::Lzma
改下这2个文件就可了：
1、/opt/theos/vendor/dm.pl/dm.pl
注释掉第12、13行
#use IO::Compress::Lzma;
#use IO::Compress::Xz;
2、/opt/theos/makefiles/package/deb.mk
第6行lzma改为gzip_THEOS_PLATFORM_DPKG_DEB_COMPRESSION ?= gzip
make: *** No rule to make target `/application.mk'. Stop.
解决：
export THEOS=/opt/theos
export PATH=/opt/theos/bin/:$PATH
theos new sdk problem solve:https://github.com/theos/theos/issues/146#issuecomment-240574611
指定SDK版本
默认是：iphone:clang:latest:latest。意即meaning to build for iOS, using clang, with the latest SDK version, deploying to support iOS versions matching the SDK version, or newer。
SDK可以放在xcode的包路径里面，或者最好的是放在theos里，然后设置路径即可。 方法如下： you should edit ~/.theosrc (which probably doesn’t exist, so create it) and insert something along the lines of:
SDKVERSION = 9.3 SYSROOT = $(THEOS)/sdks/iPhoneOS9.3.sdk
TARGET = iphone::9.2:9.0
