Error-安装doctr

如果安装doctr出现如下error:
The conflict is caused by:
    python-doctr 0.4.1 depends on mplcursors>=0.3
    python-doctr 0.4.0 depends on mplcursors>=0.3
    python-doctr 0.3.1 depends on mplcursors>=0.3
    python-doctr 0.3.0 depends on mplcursors>=0.3
    python-doctr 0.2.1 depends on mplcursors>=0.3
    python-doctr 0.2.0 depends on mplcursors>=0.3
    python-doctr 0.1.1 depends on mplcursors>=0.3
    python-doctr 0.1.0 depends on mplcursors>=0.3

 这时需要先安装mplcursors：
python

Error-安装doctr最先出现在Python成神之路。
