树莓皮上的pip安装时间慢

Question

有没有其他人在覆盆子pi上安装pip时遇到过安装速度慢的问题

在我的pi上安装python3.8之后，安装软件包需要很长时间。 有人能看到我的安装过程中有什么错误吗

sudo apt update
sudo apt upgrade -y
# build tools
sudo apt install build-essential zlib1g-dev libncurses5-dev\
 libgdbm-dev libnss3-dev libssl-dev libreadline-dev libffi-dev curl

# SSL certificate
sudo apt-get install libssl-dev

wget https://www.python.org/ftp/python/3.8.6/Python-3.8.6.tar.xz

tar -xf Python-3.8.6.tar.xz
cd Python-3.8.6
./configure
sudo make install

Then I checked my install by running:

python3 -m test

Updated pip

python3.8 -m pip install -U pip

And now it takes ages to install the package steinloss which I don't understand

python3.8 -m pip install steinloss
