项目场景：

学习知识图谱构建，安装py2neo

问题及解决过程

主要错误：依赖版本冲突
我的问题和这个博主很像，就试着改了一下版本，py2neo==4.2.0与其他包不冲突。

一、py2neo==4.0.0 + prompt-toolkit 2.0.1

ERROR: pip’s dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following depen
dency conflicts.
py2neo 4.0.0 requires prompt-toolkit==1.0.15, but you have prompt-toolkit 2.0.1 which is incompatible.

二、py2neo == 4.0.0 + prompt-toolkit==1.0.15

ERROR: pip’s dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following depen
dency conflicts.
jupyter-console 6.4.0 requires prompt-toolkit!=3.0.0,!=3.0.1,❤️.1.0,>=2.0.0, but you have prompt-toolkit 1.0.15 which is incompatible.
ipython 7.29.0 requires prompt-toolkit!=3.0.0,!=3.0.1,❤️.1.0,>=2.0.0, but you have prompt-toolkit 1.0.15 which is incompatible.

三、换了 py2neo==4.3.0，出现了更多冲突

ERROR: pip’s dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following depen
dency conflicts.
spyder 5.1.5 requires pyqt5<5.13, which is not installed.
spyder 5.1.5 requires pyqtwebengine<5.13, which is not installed.
conda-repo-cli 1.0.4 requires pathlib, which is not installed.
anaconda-project 0.10.1 requires ruamel-yaml, which is not installed.
nbconvert 6.1.0 requires pygments>=2.4.1, but you have pygments 2.3.1 which is incompatible.
jupyterlab-pygments 0.1.2 requires pygments<3,>=2.4.1, but you have pygments 2.3.1 which is incompatible.

四、换了py2neo==4.2.0，终于没有冲突了！

这是我第一次写博客，我真的很兴奋。
我希望我可以继续以这种方式记录我的学习过程。
