+# ohos-sdk 两个版本文件比对工具
+
+## 简介
+比对两个ohos-sdk版本，将两个版本共同文件以及缺失文件输出到Excel表格中
+
+## 目录
+
+```
+├─src         #存放源码
+└─test        #本地运行使用文件
+```
+
+## 环境
+
+电脑中必须配置有Python环境
+
+## 打包
+
+1、工具代码clone下来之后，需要在当前工程目录下安装打包依赖，即在 .\build-tools\compare_sdk_files 目录下进入终端，输入命令：pip install pyinstaller
+
+2、打包依赖安装完成之后，输入打包命令：pyinstaller --onefile .\src\main.py
+
+3、工具打包完成之后，会在当前工程文件下生成'build'文件夹、'dist'文件夹、main.spec文件，工具包为'dist'文件夹下的'main.exe'文件
+
+## 运行
+
+在'dist'文件夹下进入终端，运行以下命令即可运行工具
+
+```
+main.exe -N compare -P 旧版SDK路径 -M 新版SDK路径 -O 输出文件差异结果Excel表格地址
+
+例如：main.exe -N compare -P E:\unzip2\3.2.3.0\ohos-sdk -M E:\unzip2\3.2.6.3\ohos-sdk -O C:\Users\Administrator\Desktop\0325\diff.xlsx
+```
+
+> **说明：**
+> 
+> 1、需保证参数按照规定顺序输入
+> 
+> 2、旧版本SDK和新版本SDK路径必须确定在ohos-sdk目录下，且ohos-sdk目录下为linux、windows两个文件夹
+> 
+> 3、输出地址如果只填写文件路径未指定具体的输出文件名，则会在指定文件目录下输出'diff.xlsx'文件，也可将文件名拼接至输出路径中
