Newly installed Ubuntu system to compile and install Python3.7.0 environment
Newly installed systems generally have nothing, we need one by one to upgrade, install, we first look at apt-get upgrade
sudo apt-get update
Then we install what gcc environment because we need to use the installation Python3.7 C compiler
sudo apt-get gcc
We rely on it to install the environment Python3.7
sudo apt-get install libffi-dev
After installing the package Python3.7 us to download and install, and can be downloaded to the network after passing Quguan Ubuntu system, download address https://www.python.org/ftp/python/3.7.0/Python-3.7.0 .tgz or later can use shell commands in Ubuntu download, go to the location you want to download,
wget https://www.python.org/ftp/python/3.7.0/Python-3.7.0.tgz
```
下载完之后我们创建一个文件夹用于安装位置
````bash
sudo mkdir /usr/local/bin/python3.7
```
我们将终端位置移动到下载好文件的位置，然后进行解压文件
```bash
sudo tar -zxvf Python-3.7.0.tgz
```
解压完成后进入到解压好的文件夹中
```bash
cd Python-3.7.0/
```
进行配置安装位置,，这里安装位置选择刚刚我们创建的文件夹，也可以选择别的位置
```bash
./configure --prefix=/usr/local/bin/python3.7/
```
下面进行编译
````bash
sudo make
```
编译完成之后进行安装
````bash
sudo make install
```
这样python3.7.0就编译安装好了，下面我们来创建软连接,如果Ubuntu中以及有python3软连接的，我们先删除（不确定有没有的也可以删除一下）。
sudo rm /usr/bin/python3
然后进行创建软连接
````bash
sudo ln -s /usr/local/bin/python3.7/bin/python3.7 /usr/bin/python3
Soft connection has been created, now we enter python3 -v out python3.7.0 is installed successfully
These are compiled on a new Ubuntu system-wide installation of course python3.7.0
