无法安装Python 3.13的石榴包

Question

我已经尝试使用 pip 安装石榴有一段时间了，但似乎不能。它所做的就是给我这个输出。

有人有解决办法吗？

我之前也通过它安装了 Cython。我还使用 .whl 文件类型安装了 pytorch。这个包好像无法安装。

互联网上有人告诉我安装 VS C++ Build Tools，但它说“安装包丢失或损坏”。我也需要找到解决方案吗？

Answer 1

您的主要问题可能与使用 Python 3.13（这是一个最新的 Python 版本）为石榴构建轮子有关。可能存在兼容性问题。

您可以尝试以下方法：

1. 安装较早的 Python 版本，因为 Python 3.13 非常新，许多软件包尚未更新以实现完全兼容。 Python 3.11 或 3.12 会是更稳定的选择

# Create a new environment with Python 3.11
conda create -n pomenv python=3.11
conda activate pomenv

# Then try installing pomegranate
pip install pomegranate

2. 如果您必须坚持使用 3.13，请尝试从具有特定依赖项的源安装：

# First install build dependencies
pip install --upgrade pip wheel setuptools
pip install numpy scipy scikit-learn cython

# Then try pomegranate
pip install pomegranate --no-binary :all:

关于 Visual C++ Build Tools 错误（“安装包丢失或损坏”），这是一个单独但相关的问题。您将需要它来编译一些 Python 包。

修复方法如下：

a.直接从微软官方网站下载Visual Studio Build Tools安装程序

b.以管理员身份运行安装程序

c.选择“使用 C++ 进行桌面开发”工作负载

d。确保安装中包含“Windows 10/11 SDK”和“MSVC C++ Build Tools”
