我正在尝试使用 Python 的安装程序在我的 Windows 10 64 位计算机上安装 Matplotlib pip。任何建议都将不胜感激。当我尝试时，我得到了以下我无法理解的大量错误返回：
C:\Users\Todd Huffman>python -m pip install matplotlib

答案1
PyPI 上的 Matplotlib(pip从哪里绘制包) 还没有适用whl于 Python 3.8 的任何 . 文件 (截至撰写本文时)。因此 Python (正如您似乎知道的那样) 正在尝试从头开始构建，但失败了。值得一提的是，我个人在使用 Python 3.8/Matplotlib 时也遇到过类似的问题。
如果你想要一个快速的解决方案，你应该看看此页面由 Christoph Gohlke 运营。简而言之，它包含各种 Python 包的“非官方”Windows 版本，选择范围极其广泛，包括 32 位和 64 位版本的 Python 3.8 的 Matplotlib 3.1.1（matplotlib‑3.1.1‑cp38‑cp38‑win32.whl和matplotlib‑3.1.1‑cp38‑cp38‑win_amd64.whl分别）。
只需下载适合.whl您的 Python 版本的版本，然后使用例如python -m pip install nameof.whl安装 wheel。python -v如果您不知道您的 Python 版本是 32 位还是 64 位，您可以使用。
顺便提一下，除了 Python 3.8 之外，我遇到了一个问题，每次我运行 Matplotlib 脚本时，Matplotlib 3.1.1 都会使 Python 崩溃。有问题的包实际上是的 PyPI 版本numpy，特别是 OpenBLAS 的 DLL。我通过卸载的 PyPI 版本numpy并将其替换为已引用页面中的版本来解决了这个问题numpy+mkl。如果您遇到任何类似的问题，这只是一些额外的信息。
