Dockerfile 因 numba 安装的 llvm-config 错误而失败

Question

我使用 pypy 基础的 Dockerfile 失败，出现 FileNotFoundError: [Errno 2] No such file or directory: 'llvm-config' when install llvmlite，numba 的依赖项，在我的 requirements.txt 中列出

我尝试在 Debian 8 上遵循并更新Python numba / llvmlite此处的说明 - 我无法构建 llvmlite

我的错误更详细：

我不想要 conda 安装的重量。有没有办法在没有它的情况下为 pypy 实现 numba 安装？

FROM pypy:3.6-slim-stretch

RUN apt-get update && apt-get install -y gnupg wget software-properties-common
RUN wget -O - https://apt.llvm.org/llvm-snapshot.gpg.key | apt-key add - 15CF4D18AF4F7421

RUN pip install enum34

ENV LLVM_CONFIG=/usr/lib/llvm-6.0-dev/bin/llvm-config pip install numba
# ENV LD_LIBRARY_PATH /usr/lib/llvm-6.0-dev/lib/

#... other stuff

RUN apt-get clean && apt-get -y update
RUN apt-get -y install python3-dev \
    && apt-get -y install build-essential

# Add requirements
COPY requirements.txt /tmp/

# Install sphinx first as it does not work inside requirements
RUN pip install -U pip && pip install -U sphinx && pip install numpy && pip install cython &&  \
  pip install -r /tmp/requirements.txt

我希望在 pypy 上使用 numba 干净地构建 docker 映像

Answer 1

变通方法如果错误出现在 4 月 17 日之后（他们发布了新版本，请参阅历史记录）。作为解决方法，请尝试安装以前的版本

pip3 install llvmlite==0.31.0

Answer 2

“真正的”解决方案是鼓励llvmlite和/或numba为 pypy 发布一个轮子。但对于眼前的问题...

不知何故，你缺少 llvm 安装，至少根据apt-file：

$ apt-file find llvm-config |grep llvm-6
llvm-6.0: /usr/bin/llvm-config-6.0
llvm-6.0: /usr/lib/llvm-6.0/bin/llvm-config
llvm-6.0: /usr/share/man/man1/llvm-config-6.0.1.gz
