报错pip’s dependency resolver does not currently take into account all the packages that are installed

install pip tensorflow

pip install  --upgrade tensorflow  -i http://pypi.douban.com/simple/ --trusted-host pypi.douban.com

报错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 dependency conflicts.
conda-repo-cli 1.0.4 requires pathlib, which is not installed.
anaconda-project 0.10.2 requires ruamel-yaml, which is not installed.

Screenshot below

solution

Install the library which is not installed in the error message

Here I want to install pathlib library, ruamel-yaml library

pip install  --upgrade pathlib  -i http://pypi.douban.com/simple/ --trusted-host pypi.douban.com

pip install  --upgrade ruamel-yaml  -i http://pypi.douban.com/simple/ --trusted-host pypi.douban.com

Finally install the tensorflow library

pip install  --upgrade tensorflow  -i http://pypi.douban.com/simple/ --trusted-host pypi.douban.com
