ubuntu16.04安装Python3.7及可能出现问题总结

最近尝试CornerNet_Lite,需要python3.7的环境,安装流程如下:

1.安装相关依赖

sudo apt-get update

sudo apt-get install build-essential python-dev python-setuptools python-pip python-smbus

sudo apt-get install build-essential libncursesw5-dev libgdbm-dev libc6-dev

sudo apt-get install zlib1g-dev libsqlite3-dev tk-dev

sudo apt-get install libssl-dev openssl

sudo apt-get install libffi-dev

注意:若安装依赖报错

E: Could not get lock /var/lib/dpkg/lock-frontend - open (11: Resource temporarly unavailable)

E: Unable to acquire the dpkg frontend lock (/var/lib/dpkg/lock-frontend), is an other process using it
等类似的错误,出现原因是有另外一个程序正在运行导致资源被锁不可用,解决方法删除锁定文件:

sudo rm /var/lib/dpkg/lock-frontend       

sudo rm /var/lib/dpkg/lock

2.安装pyenv

 git clone git://github.com/yyuu/pyenv.git ~/.pyenv
 echo 'export PYENV_ROOT="$HOME/.pyenv"' >> ~/.bashrc
 echo 'export PATH="$PYENV_ROOT/bin:$PATH"' >> ~/.bashrc
 echo 'eval "$(pyenv init -)"' >> ~/.bashrc
 exec $SHELL -l

3.安装python3.7

pyenv install 3.7.0 -v

接着对数据库更新

pyenv rehash

查看安装版本

pyenv versions

显示:

* system (set by /home/nvidia/.pyenv/version)
3.7.0

4.设置全局python版本

pyenv global 3.7.0
