1. 背景

平常我们在安装应用时,经常会碰到缺少各种文件、依赖等问题,例如缺少.so文件。Ubuntu中提供了一个强大的工具apt-file来查找依赖。最适合的场景是在Docker中使用,因为Docker Image的系统通常是Ubuntu。

2. 安装

apt-file的安装命令如下:

# Install
$ apt-get update
$ apt-get install apt-file
# Update apt-file
$ apt-file update
3. 搜索缺少的文件

如果缺少cv.py文件,则搜索cv.py文件,apt-file会列出包含cv.py的包,发现需要的包是python-opencv,然后安装ython-opencv。

# 命令格式
$ apt-file seach [filename]
# Demo
$ apt-file search cv.py

4. 列出包中的文件

查看python-opencv中的文件。

5. 其它系统

在其它系统中,例如CentOS中,可以用yum whatprovides命令来查询命令所在的包。
