尽管我在互联网上搜索解决方案，但似乎没有任何效果。尤其是在
之后，发生了错误Collecting pywinpty>=0.5; os_name == "nt"
出于类似原因，我无法安装pyaudio。我已安装Visual Studio 2017（已卸载以前的版本）。这是一些日志-

答案 0 :(得分：2)
pywinpty尚未与Python 3.8兼容：https://github.com/spyder-ide/pywinpty/issues/123
我的建议是：不要过早升级到Python 3.8。很好的Python是可以的，但是第三方模块还没有。
答案 1 :(得分：1)
我刚刚按照以下步骤安装了Python 3.8，然后安装了JupyterLab：
从https://www.lfd.uci.edu/~gohlke/pythonlibs
下载 pyzmq 和 pywinpty 滚轮文件通过pip安装它们
pip install pywinpty-0.5.5-cp38-cp38-win_amd64.whl pyzmq-18.1.0-cp38-cp38-win_amd64.whl
然后安装JupyterLab
pip install jupyterlab
运行JupyterLab的最后一步是在龙卷风包中编辑asyncio.py。 在您的Python安装目录中，打开\ Lib \ site-packages \ tornado \ platform \ asyncio.py 并在导入异步后放置以下行
import sys
if sys.platform == 'win32':
asyncio.set_event_loop_policy(asyncio.WindowsSelectorEventLoopPolicy())
就是这样，JupyterLab应该可以发挥作用。
TL; DR
download latest versions of pyzmq and pywinpty from https://www.lfd.uci.edu/~gohlke/pythonlibs
pip install pywinpty-0.5.5-cp38-cp38-win_amd64.whl pyzmq-18.1.0-cp38-cp38-win_amd64.whl
pip install jupyterlab
edit \Lib\site-packages\tornado\platform\asyncio.py and put the following lines after import asyncio:
import sys
if sys.platform == 'win32':
asyncio.set_event_loop_policy(asyncio.WindowsSelectorEventLoopPolicy())
