【问题描述】：
我启动了 Spyder (Python 3.7) 并收到了这个警告：
C:\ANACONDA3\lib\site-packages\pandas\compat\_optional.py:138: UserWarning: Pandas requires version '2.7.0' or newer of 'numexpr' (version '2.6.9' currently installed). warnings.warn(msg, UserWarning)
如果我忽略它，我有时会收到内核连接错误（当/如果再次发生时，我会截屏）。
我尝试了pip install pandas --upgrade，希望它能升级pandas 及其所有依赖项（包括numexpr），但它只是删除了pandas 1.3.0 而没有安装pandas 1.3.4
Collecting pandas

Installing collected packages: pandas
Found existing installation: pandas 1.3.0
Uninstalling pandas-1.3.0:
Successfully uninstalled pandas-1.3.0
ERROR: Could not install packages due to an EnvironmentError: [WinError 5] Access is denied: 'c:\\users\\u03132tk\\appdata\\roaming\\python\\python37\\site-packages\\~andas\\_libs\\algos.cp37-win_amd64.pyd'
Consider using the `--user` option or check the permissions.
然后我做了pip install pandas，它成功安装了pandas 1.3.4：
print (pandas.__version__)
1.3.4
我认为一切都很好，但我又开始收到警告。当我像上面那样做pip install numexpr --upgrade 然后是pip install numexpr 时，这些就消失了。但是现在我的内核偶尔会无缘无故地重新启动。我应该做些什么来解决这个问题？
干杯！
