The ease of installing the dependent libraries is often a matter of personal luck. Sometimes a simple pip install xx or apt-get install xx can succeed, and sometimes it’s a pit of life and death, and various errors are reported. I just fell into a deep pit, and after a day of tossing, I found various solutions online, but fortunately I finally crawled out. . . If my method is useful to you, please give me a compliment, thank you
Installation environment :
pip version：19.3.1
python version：3.7.4
cmake version：3.15.3
gcc version：5.5.0
OS version：ubuntu16.04installation method:
pip install dlib==19.17.0I use version 19.17.0 here, you can also use the latest version 19.18.0, try to use a newer version, because no matter you use the new version of python3.5, 3.6 or 3.7
Can be used, do not use before 19.7.0.
If you are lucky, you can install successfully through the above line of commands. If you report the following error like me, you can use the following command to solve it (the solution can be found from the dlib official website: http://dlib.net /compile.html )
sudo apt-get install libx11-devThe error is as follows:

CMake Warning (dev) in CMakeLists.txt:
No project() command is present. The top-level CMakeLists.txt file must
contain a literal, direct call to the project() command. Add a line of
code such as
project(ProjectName)
near the top of the file, but after cmake_minimum_required().
CMake is pretending there is a "project(Project)" command on the first
line.
This warning is for project developers. Use -Wno-dev to suppress it.

In addition, if you use python setup.py install to report an error similar to the above, you can also use the above solution to solve it. Please refer to the link below for specific errors. Posting is a bit long
https://github.com/davisking/dlib/issues/1903
I originally wanted to ask the dlib code manager for this issue, but I solved it by myself, so I posted a solution later.
