Pip 安装 pandas 失败

Question

我尝试在 Windows 计算机上安装 pandas，但得到以下输出：

python -m pip install pandas

  note: This error originates from a subprocess, and is likely not a problem with pip.

我尝试了以下方法：

• 以管理员身份运行终端
• 更新点
• 安装旧版本的 pandas，因为我读到最新版本存在一些问题
• 从输出中查看日志文件，但进程完成后它不再存在

输出还是一样。

我看到它在抱怨 C 标准。我需要安装特定的编译器或任何其他先决条件吗？

谢谢。 问候， 塞尔维亚

所以我克服了这个问题，这是发生这种情况的一个愚蠢的原因。我在 MinGW 安装文件夹中的某个位置有另一个 pip 二进制文件，它总是调用该二进制文件。我确保更改环境变量以指向正确的、独立的 pip 安装（也不是 python）。
