Dockerfile因numba安装失败而出现llvm-config错误 [英] Dockerfile fails with llvm-config error for numba install

问题描述

我使用pypy的Dockerfile失败，出现FileNotFoundError：[错误2]没有这样的文件或目录：在安装llvmlite时出现 llvm-config，它是numba的依赖项，在我的要求中列出。txt

My Dockerfile using a pypy base fails with FileNotFoundError: [Errno 2] No such file or directory: 'llvm-config' when installing llvmlite, a dependency of numba which is listed in my requirements.txt

我试图遵循并更新此处的说明
在Debian 8上使用Python numba / llvmlite-我无法建立llvmlite

I tried to follow and update the instructions here Python numba / llvmlite on Debian 8 - i can't build llvmlite

我的错误更详细：

安装conda。有没有办法在没有pypy的情况下实现numba安装？

I don't want the heavy weight of a conda installation. Is there a way to achieve a numba install for pypy without it?

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 apt-add-repository "deb http://apt.llvm.org/stretch/ llvm-toolchain-stretch-6.0 main"
RUN apt-get update
RUN apt-get -y install cython python-llvm build-essential libedit-dev
RUN apt-get -y install libllvm6.0 llvm-6.0-dev llvm-dev

RUN pip install enum34
ENV LLVM_CONFIG=/usr/lib/llvm-6.0-dev/bin/llvm-config pip install llvmlite
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

我希望构建干净在pypy上使用numba的docker镜像

I expect a clean build of the docker image with numba on pypy

推荐答案

WORKAROUND 如果该错误在4月17日之后出现（他们发布了新版本，请参见历史）。
作为解决方法，请尝试安装以前的版本

WORKAROUND If the error appeared after April the 17th (they released a new version, see history). As a workaround try installing a previous version

pip3 install llvmlite==0.31.0
