在Python 3.8上安装Matplotlib时出错 [英] Error Installing Matplotlib on Python 3.8

问题描述

已解决:在Mac上安装Xcode会安装所有缺少的Matplotlib依赖项，因此我能够通过终端成功安装Matplotlib.

我目前在我的Mac OS X Catalina上拥有Python 2.7和Python 3.8(已通过Python.org下载了.dmg).我已经通过Terminal成功安装了Numpy，以及通过Terminal在Python 2.7上成功安装了Matplotlib，但是当我通过Terminal安装Matplotlib时，我总是得到两个错误代码.我曾尝试通过在线研究中的故障排除方法通过终端使用不同的输入变体，但无济于事.

I currently have Python 2.7 and Python 3.8 (downloaded the .dmg via Python.org) on my Mac OS X Catalina. I have successfully installed Numpy via Terminal, as well as Matplotlib on Python 2.7 via Terminal, but I always get two error codes when I install Matplotlib through Terminal. I've tried using different variants of inputs via terminal via troubleshooting I did in my online research, but to no avail.

输入:

pip3 install matplotlib

输出(错误#1):

推荐答案

我可以使用非官方的软件包解决此问题，您可以先下载然后

I was able to solve this by using the unnoficial packages, you can download then here and just make sure to install de requirements, you can find them on the link too, then install each package with:

pip install "SomePackage-1.0-py2.py3-none-any.whl"
