尝试安装python异步IO时失败

我尝试为python安装asyncio，但失败了 我不知道失败是否是“重叠的。c:68:error:'PyExc_ConnectionRefusedError'未声明” 或“错误：命令'c:\mingw\bin\gcc.exe'失败，退出状态为1” 解决方案是什么

命令：

C:\Users\AA>pip安装异步IO

输出：

asyncio

是Python3中的内置包，在Python2中不可用，即使通过pip安装也不可用。如果您真的需要使用协同程序，那么是时候切换到使用Python3了

除此之外，python 2还有一个名为asyncio的端口，如果您愿意，可以使用它（仍然可用，但现在已弃用）。但我仍然建议更新到Python3

---

正如您所看到的，是针对python3.3+的，它没有预先安装

asyncio

，并不意味着要替代Python2中的

asyncio

。

如果您想使用asyncio安装python3，可以。 安装python3并通过下面的命令使python3成为默认值

别名python=/usr/bin/python3 在~/.bash\u别名文件中编写此命令 sudo nano~/.bash_别名

---

当你打开你的终端时，这会自动将python路径设置为python 3。我试图安装trollius，但是我遇到了这个错误，我能做什么？谢谢！因此，通常在使用

pip

时，您应该先查看Python包索引（PyPI网站）并阅读该包的安装说明？在遇到这个问题之前，我没有这样做。
