Question

我尝试安装 PyLint。安装时我看到以下内容：

我可以卸载这里提到的软件包吗Installing collected packages: six, isort, mccabe, configparser, backports.functools-lru-cache, lazy-object-proxy, wrapt, astroid, pylint以恢复到以前的状态，还是“安装收集的软件包”也可以指以前安装的软件包？

Answer 1

有两个有用的包可以处理它。

使用该包pip-autoremove来卸载包及其依赖项。您还可以用来pipdeptree显示所有已安装软件包的树形关系。
