在觀看有關(guān)人臉識(shí)別的 YouTube 視頻后，我安裝了 Python 3.8.2，然后安裝了 CMAKE，然后安裝了 dlib。dlib 失敗并顯示以下消息。起初我有 python 32 位，然后我刪除它并安裝了 64 位版本，同樣的問題。任何想法？我在另一臺(tái)計(jì)算機(jī)上執(zhí)行了相同的流程，但出現(xiàn)了類似的錯(cuò)誤，安裝 CMake 后解決了。在這種情況下，安裝了 CMake。我錯(cuò)過了什么？C:\Users\NH5>pip install dlibDefaulting to user installation because normal site-packages is not writeableCollecting dlib  Using cached dlib-19.19.0.tar.gz (3.2 MB)Could not build wheels for dlib, since package 'wheel' is not installed.Installing collected packages: dlib    Running setup.py install for dlib ... error    ERROR: Command errored out with exit status 1:     command: 'c:\program files\python38\python.exe' -u -c 'import sys, setuptools, tokenize; sys.argv[0] = '"'"'C:\\Users\\NH5\\AppData\\Local\\Temp\\pip-install-7c571567\\dlib\\setup.py'"'"'; __file__='"'"'C:\\Users\\NH5\\AppData\\Local\\Temp\\pip-install-7c571567\\dlib\\setup.py'"'"';f=getattr(tokenize, '"'"'open'"'"', open)(__file__);code=f.read().replace('"'"'\r\n'"'"', '"'"'\n'"'"');f.close();exec(compile(code, __file__, '"'"'exec'"'"'))' install --record 'C:\Users\NH5\AppData\Local\Temp\pip-record-wm_xgg14\install-record.txt' --single-version-externally-managed --user --prefix= --compile --install-headers 'C:\Users\NH5\AppData\Roaming\Python\Python38\Include\dlib'         cwd: C:\Users\NH5\AppData\Local\Temp\pip-install-7c571567\dlib\    Complete output (57 lines):    running install    running build    running build_py    package init file 'dlib\__init__.py' not found (or not a regular file)    running build_ext    Building extension for Python 3.8.2 (tags/v3.8.2:7b3ab59, Feb 25 2020, 23:03:10) [MSC v.1916 64 bit (AMD64)]
