运行“ conda install conda”后，yum和dnf损坏

Question

我正在Fedora 27上的python3中工作，我正在尝试安装anaconda。运行conda install conda之后，yum和dnf都坏了。现在我收到以下错误。

Traceback (most recent call last):
  File "/usr/bin/dnf", line 57, in <module>
    from dnf.cli import main
  File "/usr/lib/python3.6/site-packages/dnf/cli/__init__.py", line 30, in <module>
    from dnf.cli.cli import Cli  # :api

  File "/usr/lib/python3.6/curses/__init__.py", line 13, in <module>
    from _curses import *
ImportError: libncursesw.so.5: cannot open shared object file: No such file or directory

有人可以帮助我吗？
