Hello zhangdengwei!

We believe that this post does not fit the main topic of this site.

Not a bioinformatics question

For this reason we have closed your question. This allows us to keep the site focused on the topics that the community can help with.

If you disagree please tell us why in a reply below, we'll be happy to talk about it.

Cheers!

In addition to what bioExplorer wrote, if you post a question like this online and expect help you would have to provide more information:

• your operating system
• python version
• pip version
• detailed error

Also note that https://pypi.org/project/tre/ tells you:

This is the python bindings only - you will need to have installed the tre library already, either using your OS’s package manager (‘brew install tre’, ‘sudo apt-get install tre’, etc.) or by compiling it yourself.
