Python 不可能通过pip安装安装软件包（pywin32、win10toast和许多其他软件包）

我已经安装了python 3.8，需要安装pywin pywin32

然而，皮普找不到它。注意，我以前曾尝试在终端中使用pip install命令安装其他一些软件包，但这些软件包也不起作用

一些可能相关的数据点：

python 3.8.1的新安装

windows 10 x64

python 3.7以前安装在机器上

我正在使用pycharm 2019.3.3。在venv/Lib/site软件包中显示安装了setuptools和pip

我在pycharm中使用终端，因为它是唯一一个让我转到路径系统C:-->windows的正常命令总是在M:，即使我更改目录，它也总是回到M:我不知道为什么

我尝试的是：

*cmd -> netsh winhttp show proxy  #As I thought the installation problems might relate to the proxy. But it doesn't because at work we don't use one, it's DirectAccess (no proxy).

你能帮我吗？ 此外，如果已经有一个主题是有益的，我会很高兴。我浪费了几个小时搜索这个网站，但是有太多

我是如何解决这个问题的： 我想为Windows任务栏编写一个带有弹出通知的代码。因此，我想使用win10toast，但pip无法安装-我检查了要求，有必要先安装pywin32和setuptools。因此，setuptools是预安装的，因此可以。 但是pywin32安装是不可能的。 如果你能给我一个比win10toast更好的解决方案，这也会很有帮助-

万分感谢！祝您一天快乐：

您可以使用plyer而不是win10toast，只需安装并编写

From plyer import notification
a= Notification.notify(title= ,message=,icon=,time=)

如果您试图在没有venv的情况下从cmd运行pip安装pywin32，那么pip安装是否有效？我如何在没有venv的情况下运行它@Flyingtellerj必须打开cmd并键入命令，假设您已将python添加到PATHYes我已经尝试了很多次…相同的错误：警告：重试Retrytotal=0，connect=None，read=None，redirect=None，连接被“NewConnectionError”断开后状态=None:无法建立新连接：[Errno 11001]getaddrinfo失败：/simple/pywin32/ERROR:无法从版本中找到满足pywin32要求的版本：无错误：未找到与pywin32I匹配的发行版我不知道…：
