我正在尝试使用 pip 在 VScode 中安装 bertopic，并且我正在使用虚拟环境，但在构建句子时遇到 Winerror2。
我尝试单独安装sentpiece，但出现了同样的错误。
我使用的是python版本3.12.0和pip版本23.3.2

我也可以下载其他库，但只有 bertopic 时才会出现错误。
考虑降级你的Python版本，一些库与python 3.12不完全兼容。
如果您使用conda，您可以使用特定版本的Python创建conda环境：
conda create --name myenv python=3.11
激活虚拟环境：
conda activate myenv
您可以使用
pipbertopicpip install bertopic
