Install dlib step pit record, error: WARNING: pip is configured with locations that require TLS/SSL

Recently I have been taking time to learn opencv - python, when I installed the dlib library today, I reported an error and recorded itStepping on the pit process.

In the beginning, it is natural to open a command window and start the installation:

pip install dlib -i https://pypi.tuna.tsinghua.edu.cn/simple

However, an error is reported:
WARNING: pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.

I found a lot of solutions, they are: (It doesn't work, at leastI tried to no avail)

• Download SSL Installation
• Update pip (I'm already up to date)
• Various uninstalls and reinstalls

Solution:

Add your Anaconda directories to the environment variable:

Your Anaconda installation path\AnacondaYour Anaconda installation path \ScriptsYour Anaconda installation path \Anaconda\Library\bin

Add to the path of the system:

install again, no WARNING: pip is configured with locations that require TLS/SSL, prompt: missing CMakemodule

Install CMake:

pip install CMake -i https://pypi.tuna.tsinghua.edu.cn/simple

Install again: dlib

pip install dlib -i https://pypi.tuna.tsinghua.edu.cn/simple

Success!

The above is installed in the default virtual environment!

Under anaconda:

1. Enter your own virtual environment first:
cmd:activate your virtual environment name
2. Enter the installation command:

conda install -c conda-forge dlib
