无法在 PyCharm 中安装软件包

Question

我一直在尝试在我使用的 IDE PyCharm 中安装一些用于数据科学的 Python 包：NumPy、Pandas 等。它不断显示“安装包‘name_of_package’时发生错误。详细信息...” 这是错误消息：

可能是什么问题？

我尝试在终端中使用 pip install 命令，但出现了同样的错误。

也许你应该创建一个虚拟环境来将 python 依赖项与你的 PC 依赖项分开！

使用：python3.11 -m venv name_of_your_env

并使用以下命令激活它：./env/Scripts/activate.ps1

然后安装你的软件包
