Question

我是python的新手，下载后我尝试下载一些软件包，但它们都给出了很长的错误：

pip install pandas

      Note: if you need reliable uninstall behavior, then install
      with pip instead of using `setup.py install`:

        - `pip install .`       (from a git repo or downloaded source
                                 release)
        - `pip install numpy`   (last NumPy release on PyPi)

它一直不可用，有时与pg_config executable not found一起使用，我在python 3.9和Windows 10上运行，我尝试了其他一些堆栈溢出问题解决方案，但它们都适用于Windows。

编辑：我安装了测试pip和networkx，错误针对的是熊猫和matplotlib

您可以尝试安装较低版本的Python，例如Python 3.8或Python 3.7吗？

如果您仍想继续使用Python 3.9，则需要安装两个Visual Studio dist软件包：

下载Visual C ++ Build Tools安装程序并从此处安装：http://go.microsoft.com/fwlink/?LinkId=691126&fixForIE=.exe
转到此链接并下载设置并安装Visual Studio 2015的Visual C ++ Redistributable：https://www.microsoft.com/en-in/download/details.aspx?id=48145

尝试再次安装所需的软件包。

无法安装任何东西
