嵌入式Python3.8.0如何安装pip？

[哈特比尔波]

我在我的windows 10系统配置python3.8.0时遇到了以下问题，请大家帮忙解决以下这个问题。
我说下具体的情况：
我从python官网上下载了window版本的python3.8.0的压缩包，将其解压到D:\python3.8.0下，并配置相应的系统环境变量。
接着我需要安装pip，以便后续安装其他需要的python库。
但是发生了如下问题：这个get-pip.py是我根据pip的安装文档找到的连接下载的文件，并将其放在了python3.8.0文件夹下。接着就发生了下面代码上的事情。恳求大家帮忙处理下这个问题。谢谢！

打开python目录下的python38._pth ，去掉#import site 行的#号，重新运行 D:\python3.8.0\python.exe get-pip.py 即可，我在window下安装的。测试通过，安装了更多其他模块。阿弥陀佛。哈哈。

好的，我试试。

我已经重新下载最新的Python3.8.1稳定版本的安装包。压缩包实在没有耐心研究了。用安装包，直接搞定。

Time Out 网络原因，建议换源

谢谢，以前没有听说过python还有源的这个情况。 只知道ubuntu 更新系统有换源的这种操作，后来才知道linux都有这个说法。 今天也算是知道了程序更新也有源这种说法。谢谢！
