“pip install mysqlclient”说要更新python？

在浏览 requirments.txt 文件时，它会进入 mysqlclient 并出现错误：

  Running setup.py install for mysqlclient ... error

据我所知，它希望我更新 python，但我无法通过我能找到的任何命令来更新。

apt-get python3已经是最新版本并且pip install python3已经安装。pip install --upgrade python3表示它已经是最新版本。

我已经完成apt-get update并apt-get upgrade重新启动了两次。

这不是真正的错误。仔细看看最后几行：

unable to execute 'x86_64-linux-gnu-gcc': No such file or directory
error: command 'x86_64-linux-gnu-gcc' failed with exit status 1

您缺少一些依赖项，包括编译器。应安装以下软件包：

sudo apt-get install build-essential python-dev python3-dev

然后重试。

请注意，pip和python指的是您系统上运行的 Python 2.x 版本，而pip3和python3指的是您的 Python 3.x 版本。您可以选择在哪个版本下运行程序，只需注意其中的区别即可。
