使用 pypy 库的我的 Dockerfile 失败，并出现 FileNotFoundError: [Errno 2] No such file or directory: 'llvm-config' 安装 llvmlite 时，numba 的依赖项列在我的 requests.txt 中
我尝试遵循并更新此处的说明 Debian 8 上的 Python numba / llvmlite - 我无法构建 llvmlite
我的错误更详细：

我不想要 conda 安装的沉重负担。有没有办法在没有它的情况下实现 pypy 的 numba 安装？

我希望在 pypy 上使用 numba 干净地构建 docker 镜像
解决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）。 作为解决方法，请尝试安装以前的版本
pip3 install llvmlite==0.31.0
目前 numba 无法安装在 python 3.9 上。
我将基本 docker 镜像从
python:3.9-slimpython:3.8-slimpip install numba这为我解决了问题 -
RUN echo "deb http://apt.llvm.org/xenial/ llvm-toolchain-xenial-8 main" >> /etc/apt/sources.list
RUN echo "deb-src http://apt.llvm.org/xenial/ llvm-toolchain-xenial-8 main" >> /etc/apt/sources.list
RUN apt-get install -y --no-install-recommends libedit-dev build-essential
RUN apt-get install -y --no-install-recommends llvm-8 llvm-8-dev
RUN LLVM_CONFIG=/usr/bin/llvm-config-8 pip3 install enum34 llvmlite numba
使用版本 8，因为最新的 llvm 版本出现错误 -
RuntimeError: Building llvmlite requires LLVM 7.0.x, 7.1.x or 8.0.x, got '3.7.1'
要在 macOS 上的 Python 3.9 上安装
numba# install llvm using MacPorts
sudo port install llvm-10
sudo port install llvm_select
sudo port select --set llvm mp-llvm-10
# set environment variable used when building `llvmlite`
export LLVM_CONFIG=/opt/local/bin/llvm-config
# clone, build, and install `llvmlite`
# http://llvmlite.pydata.org/en/latest/admin-guide/install.html#compiling-llvmlite
git clone [email protected]:numba/llvmlite.git

llvmlitenumba根据https://askubuntu.com/questions/1286131/how-do-i-install-llvm-10-on-ubuntu-18-04 我在 Dockerfile 中添加了以下行
RUN apt-get -y install llvm-10*
RUN rm -f /usr/bin/llvm-config
RUN ln -s /usr/bin/llvm-config-10 /usr/bin/llvm-config
并且它有效（
llvmlite这是从 github issues thread 获得的解决方案，对我有用！本质上，
pip--upgrade pip \
这是我的 Dockerfile 示例：
# Docker commands here ...
RUN APT_INSTALL="apt-get install -y " && \
PIP_INSTALL="python3 -m pip install " && \
apt-get update && \
# more docker commands here ...
DEBIAN_FRONTEND=noninteractive $APT_INSTALL \
python3.6 \
python3.6-dev \
python3-distutils-extra \
python3-pip && \
ln -s /usr/bin/python3.6 /usr/local/bin/python3 && \
$PIP_INSTALL \
--upgrade pip \ # adding this line was my solution
setuptools \
&& \
$PIP_INSTALL \
numpy==1.18.5 \
# more docker commands here...
这是针对 python 3.6 的
我在使用 python3.8 时遇到了这个问题，但最终的解决方案是将我的 PIP 更新到版本 23.0.1，它解决了问题。
尝试
sudo apt-get install llvm
