python - Numba 运行时链接错误

Question

我正在尝试导入 numba。我使用此处找到的说明 (https://github.com/numba/numba#custom-python-environments) 安装了 llvmlite 和 numba，但是在导入 numba 时出现以下错误。

Traceback (most recent call last):

我在 Ubuntu 14.04 上的 llvm 3.6 遇到了类似的问题。尝试:

apt-get install gcc-4.8 g++-4.8 libedit-dev llvm-3.6-dev
LLVM_CONFIG=/usr/lib/llvm-3.6/bin/llvm-config CC=/usr/bin/gcc-4.8 CXX=/usr/bin/g++-4.8 pip install numba
