Result

"Compression requires the (missing) zlib module"

Yum install zlib

Yum install zlib-devel

After the installation is complete, recompile python2.7. [you do not need to delete it. You only need to re-compile, make, and install it]
Make
Make install

I found that I deleted it before, so I re-compiled it.

Reload python2.7.

There are a lot of things in python, the dependency is strange, obviously installed, still prompts lack, so just reinstall python.

After installing and updating Python on CentOS recently, the following error occurs: ImportError: cannot import name HTTPSHandler.

Solution:

You must install OpenSSl before installing python.

The command is as follows:

Centos:

Yum install openssl-devel-y

Debian or Ubuntu:

Apt-get install libssl

And then reinstall Python.
So I went back to reinstall python.

Pip install xlwt
