Running phpize does not require you to enter the directory of phpize to run, but to run it in the source code directory. Run /usr/bin/phpize directly in the source directory without changing directories. The directory environment is a very important part of executing a program. When you refer to other people's code, you should pay attention to other people's directory structures.

Translate the error message for you: Make sure /usr/bin/phpize is running in the root directory of your source code

This is someone else’s path, you can’t copy it.
Check where phpize is:
which phpizewhich phpize
如果你的PHP是用yum安装的话，应该是在/usr/bin，那么直接运行phpizeIf your PHP is installed with yum, it should be in /usr/bin, then run phpize will do.
