python - llvmlite 安装失败。构建 llvmlite 时出错

Question

我在安装 llvmlite 时遇到问题，这是安装 Numba 所必需的。
我搜索了我的问题的答案，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，我一直在寻找解决此问题的方法2天，但没有成功，我很绝望

去 to here并为您的 python 版本下载 llvmlite 包，例如llvmlite‑0.35.0‑cp39‑cp39‑win_amd64.whl对于 Python 3.9。
然后安装 pip install llvmlite‑0.35.0‑cp39‑cp39‑win_amd64.whl .
可能 llvmlite 尚未在 Python 3.9 上得到正式支持。这就是为什么只有像本网站这样的非官方版本。
此外，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 .此站 pip 所有者尚未为 Python 3.9 编译最新的 numba 0.52.0，只有 0.51.2 版。
此外，在安装 numba 时，您可能需要传递 key --no-deps pip 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:

pip install llvmlite‑0.35.0‑cp39‑cp39‑win_amd64.whl (来自 here 的 .whl 文件)。

pip install --no-deps numba‑0.51.2‑cp39‑cp39‑win_amd64.whl (来自 here 的 .whl 文件)。

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)。

附注。上面提到的通过链接的站 pip 只有 Windows 软件包。此外，该站 pip 还有许多其他流行的 Python 轮子包，其中大部分都放置在此站 pip 上，因为它们目前在官方 PIP 存储库中不可用。
