无法在命令提示符中使用 pip 下载 streamlit
我尝试使用 pip 在 window10 中安装 streamlit,但在安装构建依赖项后出现以下错误:

这只是错误的一小部分,错误很长。我该怎么做才能解决这个问题?
由于您使用的是 Windows,请尝试安装或检查这两个 Visual Studio dist 包是否已安装:
-
Visual C++ Build Tools 安装程序: http://go.microsoft.com/fwlink/?LinkId=691126&fixForIE=.exe
-
转到此链接并下载安装程序并安装 Visual Studio 的 Visual C++ Redistributable: https://www.microsoft.com/en-in/download/details.aspx?id=48145
尝试再次安装所需的 python 包。
否则,作为提示,尝试创建一个虚拟环境并在那里继续安装。另外,我可能会检查 python 版本。我在尝试使用 python3.8 时遇到了这个问题,所以如果您现在使用的是 python3.8,也许您可​​以使用 3.7。;)
我认为这个问题出在你的 NumPy 库上。
你的 numpy 是如何安装的?如果你还没有安装 conda,我建议你使用它。Numpy 在 Windows 上构建时有时会出现问题。
我会给你一个 conda 安装链接,你可以试试这个方法。 https://docs.conda.io/projects/conda/en/latest/user-guide/install/windows.html
