无法在pycharm上安装pandas包

Question

我在 Pycharm 上安装 pandas 包时遇到问题

我收到以下错误

`(venv) PS C:\Users\merta\PycharmProjects\pythonProject2> pip install pandas

我尝试更改解释器，通过终端和pycharm选项安装pandas，但它不起作用

我不明白与 vswhere 的链接

谢谢您的帮助

Answer 1

您遇到的错误似乎与使用 Meson（一个构建系统）构建 Pandas 包的问题有关。它似乎试图从 Microsoft Visual Studio 中查找名为 vswhere.exe 的工具，但找不到它。这可能是由于 Visual Studio 安装不完整或不正确或配置错误造成的。

解决这个问题

---

安装 Visual Studio

---

升级 Pip 和设置工具

python -m pip install --upgrade

pip python -m pip install --升级安装工具

---

使用虚拟环境

python -m venv myenv

.\myenv\Scripts\激活

---

使用预建

pip安装pandas==2.1.1

---

如果不使用此工作

conda 安装 pandas
