Numba運行時鏈接錯誤

Question

我正試圖導入numba。我使用這裏找到的說明（https://github.com/numba/numba#custom-python-environments）安裝了llvmlite和numba，但是在導入numba時出現以下錯誤。

Traceback (most recent call last):

我在Ubuntu 14.04上遇到了類似llvm 3.6的問題。試試：

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
