这是一个非常受欢迎的问题，但我所看到的许多答案中，没有一个能清楚地解释这个错误的真正含义，以及它为什么会发生。
混淆的一个来源是，当(例如)你执行pip install pycparser时，你首先得到错误:
pycparser构建转轮失败
后面跟着一个消息，这个包是:
成功安装pycparser-2.19。
# pip3 install pycparser

这是怎么回事?
(我想了解一些东西是如何失败的，但仍然可以安装，以及您是否可以相信这个包正常运行?)
到目前为止，我找到的最好的部分解释是这样的。
错误:
系统:aws ec2实例(t2小)
问题:在安装opencv python via
Pip3安装opencv-python
Problem with the CMake installation, aborting build. CMake executable is cmake
----------------------------------------
Failed building wheel for opencv-python
Running setup.py clean for opencv-python
什么对我有用
Pip3安装——升级PIP setuptools轮
在此之后，您仍然可能收到休闲错误错误
from .cv2 import *
ImportError: libGL.so.1: cannot open shared object file: No such file or directory
安装libgl为我解决了这个错误。
sudo apt update
sudo apt install libgl1-mesa-glx
希望这能有所帮助
在我的例子中，在创建venv后更新pip versión，这将pip从9.0.1更新到20.3.1
python3 -m venv env/python
source env/python/bin/activate
pip3 install pip --upgrade
但是，信息是…
Using legacy 'setup.py install' for django-avatar, since package 'wheel' is not installed.
然后，我在更新pip后安装车轮包
python3 -m venv env/python
source env/python/bin/activate
pip3 install --upgrade pip
pip3 install wheel
信息是…
Building wheel for django-avatar (setup.py): started
default: Building wheel for django-avatar (setup.py): finished with status 'done'
错误:
系统:aws ec2实例(t2小)
