在 PyCharm (macOS) 中安装 dlib 的问题

Question

I am a beginner in the Python programming language. I am Working on a project for facial landmark detection in Python. For this I am trying to use dlib.

I am using PyCharm IDE for Python programming language, but when I am trying to install dlib library on my PyCharm package then I am getting the following error.

Can anyone please help me solving this.

Edit: Here is the complete error that I am getting.

Answer 1

conda install cmake

Then

pip install dlib

It works for me.

Answer 2

Refer Answer from this link and try, circleci: pip install dlib fails

you can download Anaconda from here, https://www.anaconda.com/distribution/#download-section

And all package can found in, https://repo.anaconda.com/pkgs/main/win-64/

Answer 3

I have found the answer to this question. We just need to follow simple steps to install dlib in Python.

1. Install Python
2. Install Pycharm
3. Install Anaconda

Open anaconda, create a new enviornment, and then execute the following commands in the same order.

• conda update conda

• conda update anaconda

• conda install cmake

• conda install -c conda-forge dlib

Now in this way you can install dlib on anaconda's virtual enviornment. Next you can access this virtual enviornment inside your Pycharm editor.
