从源码安装 Python3.7 [英] Installing Python3.7 from source
本文介绍了从源码安装 Python3.7的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我需要使用Python3.7,所以我按照这些说明安装
I need to use Python3.7, so I followed these instructions to install it
curPath=${pwd}
cd /usr/src
sudo wget https://www.python.org/ftp/python/3.7.9/Python-3.7.9.tgz
sudo tar xzf Python-3.7.9.tgz
cd Python-3.7.9
sudo ./configure --enable-optimizations
cd ${pwd}
然后我尝试运行 python -V
并得到
I then tried to run python -V
and got
Command 'python3.7' not found, did you mean:
command 'python2.7' from deb python2.7 (2.7.18-1~20.04)
command 'python3.9' from deb python3.9 (3.9.0-5~20.04)
command 'python3.8' from deb python3.8 (3.8.5-1~20.04.2)
Try: sudo apt install <deb name>
我也尝试运行 whereis python
并得到
Also I tried to run whereis python
and got
whereis python
python: /usr/bin/python3.8 /usr/bin/python3.8-config /usr/lib/python3.8 /usr/lib/python2.7 /usr/lib/python3.9 /etc/python3.8 /usr/local/lib/python3.8 /usr/include/python3.8
推荐答案
通过这个脚本,我能够在 ubuntu 18 上安装 python3.7
With this script, I was able to install python3.7
on ubuntu 18
curPath=${pwd}
sudo apt-get update
sudo apt-get install gcc
sudo apt-get install libreadline-gplv2-dev libncursesw5-dev libssl-dev libsqlite3-dev tk-dev libgdbm-dev libc6-dev libbz2-dev libffi-dev wget liblzma-dev lzma
cd /usr/src
sudo wget https://www.python.org/ftp/python/3.7.9/Python-3.7.9.tgz
sudo tar xzf Python-3.7.9.tgz
cd Python-3.7.9
sudo ./configure --enable-optimizations
sudo make
sudo make altinstall
cd ${pwd}
但是您可能应该使用 pyenv
安装它,这里有一个脚本,它将在 linux 上安装 pyenv
,然后安装 python 3.7.9 .这种方法发生的速度要快很多,第一次安装大约需要一个小时.
But you should probably just install it with pyenv
, here's a script that will install pyenv
on linux, and then install python 3.7.9 . This method happens a lot faster, the first installation takes about an hour.
sudo apt-get install gcc build-essential libreadline-gplv2-dev libncursesw5-dev libssl-dev libsqlite3-dev tk-dev libgdbm-dev libc6-dev libbz2-dev libffi-dev liblzma-dev lzma
curl https://pyenv.run | bash
bashrc="${HOME}/.bashrc"
bash_profile="${HOME}/.bash_profile"
profile="${HOME}/.profile"
checkAndAppend () {
# Checks if some text is in a file, and if it isn't, it appends that text at the end of the file
# $1 - The text to insert into a file
# $2 - A file to insert text into
if ! grep -q $2 <<< "${1}" ; then
echo $1 >> $2
fi 2>/dev/null
}
checkAndAppend 'export PYENV_ROOT="$HOME/.pyenv"' $profile
checkAndAppend 'export PATH="$PYENV_ROOT/bin:$PATH"' $profile
checkAndAppend 'eval "$(pyenv init --path)"' $profile
checkAndAppend 'eval "$(pyenv init -)"' $bashrc
checkAndAppend 'eval "$(pyenv virtualenv-init -)"' $bashrc
checkAndAppend 'source $HOME/.profile' $bash_profile
RED='\033[0;31m'
printf $RED'
If your $HOME/.profile sources $HOME/.bashrc, then these lines must be inserted into $HOME/.profile before that
export PYENV_ROOT="$HOME/.pyenv"
export PATH="$PYENV_ROOT/bin:$PATH"
eval "$(pyenv init --path)"
'
source $profile
source $bashrc
source $bash_profile
pyenv install 3.7.9
