llvmlite安装失败。生成llvmlite时出错

Question

我在安装llvmlite时遇到问题，这是安装Numba所必需的。 我在寻找我问题的答案，但什么都没用。 我用于安装numba和llvmlite的命令：

pip install numba

pip install llvmlite

    enter code here

请帮帮我，我已经找了两天的方法来解决这个问题，但是没有成功，我绝望了

Answer 1

使用命令安装大于7的llvm{版本}

suda apt install llvm-{version}

而不是安装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

Answer 2

转到to here并下载适用于python版本的llvmlite包，例如适用于python 3.9的llvmlite‑0.35.0‑cp39‑cp39‑win_amd64.whl

然后安装pip install llvmlite‑0.35.0‑cp39‑cp39‑win_amd64.whl

Python3.9可能还没有正式支持llvmlite。这就是为什么在这个网站上只有非官方的版本

另外，如果您需要numba，那么go to here并下载/安装numba‑0.51.2‑cp39‑cp39‑win_amd64.whl。最新版本的numba 0.52.0尚未由该网站所有者为Python 3.9编译，只有版本0.51.2

此外，在安装numba时，您可能需要将--no-deps键传递给pip以忽略安装依赖项，如pip install --no-deps numba‑0.51.2‑cp39‑cp39‑win_amd64.whl，因为默认情况下，numba 0.51.2需要稍旧一点的llvmlite版本。此外，还需要手动安装很少的额外依赖项。因此，在Win Python 3.9 64位上安装的所有步骤如下：

1. pip install llvmlite‑0.35.0‑cp39‑cp39‑win_amd64.whl（.whl文件来自here）
2. pip install --no-deps numba‑0.51.2‑cp39‑cp39‑win_amd64.whl（.whl文件来自here）
3. pip install numpy importlib-metadata（通过常规pip安装而不下载的少量额外依赖项）

上面提到的链接站点只有Windows软件包。此外，该网站还有许多其他流行的Python wheels软件包，其中大多数都放在该网站上，因为它们目前在官方PIP存储库中不可用

Answer 3

llvmlite还不支持python 3.9Uninstallpython3.9，下载python 3.8.7，然后重试。这为我解决了这个问题
