我无法在python 3.8上从pip安装熊猫。
它给了我以下长时间错误：
PS C:\Users\Admin> pip install pandas

不幸的是，自2019年10月18日起，它不起作用。我在LinkedIn上收到了此回复：
您需要安装cython来构建本机位，直到释放具有本机位的轮子为止。
Checked under 'docker run --rm -i -t python:3.8-slim bash'
'pip install pandas' failed with the clear message
Exception: Cython-generated file 'pandas/_libs/algos.c' not found.
Cython is required to compile pandas from a development branch.
Please install Cython or download a release package of pandas.
apt-get update && apt-get -y install cython && pip install pandas is still chugging along compiling.
And that failed with a missing 'cc1plus'... so 'apt-get -y install g++-8' and chugging again.
And much later it can't find g++.
'apt-get -y install g++'
You're responsible for chasing build environments on your own when you choose bleeding edge open source software.
'pip install --no-binary :all: ...' is a great training exercise. And tools like docker simplify creating a pristine environment to double check your assumptions. (edited)
答案 1 :(得分：4)
请尝试使用以下任何代码进行安装。
easy_install pandas
pip install --only-binary :all: pandas
希望以上代码可以帮助您解决问题。
答案 2 :(得分：0)
我的安装似乎可以在Windows 10上进行-我必须确保Wheel在Path中，切换到Python 3.8目录并运行 python -m pip install --upgrade pip setuptools滚轮 然后我
