llvmlite 安装失败。构建 llvmlite 时出错

问题描述 投票：0回答：6

我在安装 llvmlite 时遇到问题，这是安装 Numba 所必需的。 我寻找问题的答案，但没有任何效果。 我用来安装 numba 和 llvmlite 的命令：

pip install numba

pip install llvmlite

    enter code here

请帮助我，我已经寻找解决这个问题的方法两天了，但没有成功，我很绝望

前往此处并下载适合您的Python版本的llvmlite包，例如

llvmlite‑0.35.0‑cp39‑cp39‑win_amd64.whl
适用于 Python 3.9。

然后安装

pip install llvmlite‑0.35.0‑cp39‑cp39‑win_amd64.whl
。

Python 3.9 可能尚未正式支持 llvmlite。这就是为什么只有像这个网站上这样的非官方版本。

此外，如果您需要 numba，请转到此处并下载/安装

numba‑0.51.2‑cp39‑cp39‑win_amd64.whl
。该网站所有者尚未为 Python 3.9 编译最新的 numba 0.52.0，仅版本 0.51.2。

此外，在安装 numba 时，您可能需要将密钥 

--no-deps
传递给 pip 以忽略安装依赖项，例如 
pip install --no-deps numba‑0.51.2‑cp39‑cp39‑win_amd64.whl
，因为 numba 0.51.2 默认情况下需要较旧版本的 llvmlite。还需要手动安装一些小的额外依赖项。因此，在 Win Python 3.9 64 位上安装的所有步骤是：

  1. pip install llvmlite‑0.35.0‑cp39‑cp39‑win_amd64.whl
    （来自此处的.whl 文件）。
  2. pip install --no-deps numba‑0.51.2‑cp39‑cp39‑win_amd64.whl
    （来自此处的.whl 文件）。
  3. pip install numpy importlib-metadata
    （通过常规 pip 安装无需下载即可获得少量额外依赖项）。

PS。上述链接站点仅包含 Windows 软件包。此外，这个网站还有许多其他流行的 Python 轮子包，其中大多数都放在这个网站上，因为它们目前在官方 PIP 存储库中不可用..

使用命令安装 llvm {version} 大于 7 :

sudo apt install llvm-{version}

安装 numba 或 llvmlite {package} 使用命令：

LLVM_CONFIG={path to llvm-config file} pip install {package}

例如（对于 llvm 版本=8）：

LLVM_CONFIG=/usr/bin/llvm-config-8 pip install numba==0.48

llvmlite 尚不支持 python 3.9。 卸载 python 3.9 并下载python 3.8.7，然后重试。这解决了我的问题。

另一种方法是安装直接兼容Python 3.9的llvmlite版本。 今天我用

pip install llvmlite==0.36.0rc1
成功做到了这一点；您可能想使用其他最新版本。

恢复到 python 3.8，一切正常。它仍然会抱怨某些语料库，但相对容易弄清楚这一点。

恢复到 Python 3.8 对我有用：

conda activate
conda create --name py38 python=3.8  # or just conda install python==3.8

然后剩下的。当我收到你提到的错误时，我已经拥有了所有依赖项。
