Ubuntu 14.04-Pylern2安装：在$PATH上找不到nvcc编译器

我正试图在我的Ubuntu 14.04上安装pylearn2 键入“python setup.py develope”命令时失败 并获取nvcc&x86_64-linux-gnu-gcc致命错误

joeson@joeson-Lenovo-G40-70m:~/KuaiPan/MachineLearning/Deep Learning/Practical Implementation/Deep Reinforcement Learning/deep_q_rl-master/build/pylearn2$ ***sudo python setup.py develop***

我得到一个nvcc编译器错误，声明找不到$PATH

**ERROR (theano.sandbox.cuda): nvcc compiler not found on $PATH. Check your nvcc installation and try again.**

我认为有些不推荐使用的Numpy软件包在安装过程中失败

我不知道x86_64-linux-gnu-gcc在这里发生了什么，是否发生了一些致命错误
