我正在尝试使用pip在python 3.8.1的Mac OS Mojave上安装python软件包pycuda。我写：
python -m pip安装pycuda
但是经过多次试验，我总是以相同的错误结尾：
错误：命令'clang'失败，退出状态为1
我做了： 出口CC = / usr / bin / clang 导出CXX = / usr / bin / clang ++ 在我的.profile文件中，但这没有帮助。
在终端上写的文字的最后一部分说：
90 warnings generated.

答案 0 :(得分：0)
这是实际错误：
ld：找不到-lcuda库
编译器找不到您的CUDA C库。您必须先安装它，和/或确保它在编译器可以找到它的位置。
另请参阅this question，以了解如何在OSX上安装CUDA。
如果您使用conda，也可以这样做
$ conda install cudatoolkit
安装CUDA工具包的版本。
