我正在尝试使用 obs 构建 deb 文件(开放式构建服务），但是，当我执行时osc build --local-package，出现以下错误：
[ 269s] make[1]: Entering directory '/usr/src/packages/BUILD'
[ 269s] cython --cplus msgpack/*.pyx
[ 269s] /bin/sh: 1: cython: not found
[ 269s] Makefile:7: recipe for target 'cython' failed
[ 269s] make[1]: *** [cython] Error 127
[ 269s] make[1]: Leaving directory '/usr/src/packages/BUILD'
[ 269s] dh_auto_build: make -j1 returned exit code 2
[ 269s] debian/rules:18: recipe for target 'build' failed
[ 269s] make: *** [build] Error 2
[ 269s] dpkg-buildpackage: error: debian/rules build gave error exit status 2
似乎 /bin/sh 没有找到 cython。而 cython 已安装在我的 ubuntu 中。
$ which cython
/usr/bin/cython
$ cython --version
Cython version 0.23.4
有人能帮助我吗？谢谢
