# 编译源码

对于 `Debian/Ubuntu`，执行：

```
sudo apt install -y zlib1g zlib1g-dev libffi-dev openssl libssl-dev
```

对于 `RedHat/CentOS/Fedora`，执行：

```
yum install -y zlib zlib-devel libffi-devel openssl openssl-devel
```

对于 `macOS`，执行：

```
xcode-select --install
```

## 编译、安装

进入 Python 源码根目录，执行以下命令：

```
./configure
make
make install
```

Python 将会被编译，并安装在默认目录中。若您希望将 Python 安装在特定目录，则需要在一开始修改 `configure` 命令为：

```
./configure --prefix=<Python要安装到的目录（绝对路径）>
```

在指定目录中:

* **bin 目录** 存放的是可执行文件
* **include 目录** 存放的是 Python 源码的头文件
* lib 目录存放的是 Python 标准库
  * **lib/python3.7/config-3.7m-{platform} 目录** 存放的是 libpython3.7m.a，该静态库用于使用 C 语言进行扩展。`{platform}` 代表平台，比如在 Mac OS 上为 “darwin”，在 Linux 上为 “x86\_64-linux-gnu”
* **share 目录** 存放的是帮助等文件

如需重新编译，请首先执行：

```
make clean
```

再执行本节开头处的命
