1. 问题介绍

由于Code Runner插件的工作目录与文件执行目录不同，而导致路径错误！

示例演示：
创建根目录test-dir，然后在里面分别创建两个目录code和data，分别存放Python程序read_file.py和输入数据input.txt

read_file.py内容为：

def read_and_write_file(input_file_path, output_file_path):
    try:
        with open(input_file_path, 'r', encoding='utf-8') as file:
            content = file.read()
        
        output_content = f"I get {content}"
        
        with open(output_file_path, 'w', encoding='utf-8') as file:
            file.write(output_content)
        
        print(f"Content from {input_file_path} has been written to {output_file_path}.")
    except FileNotFoundError:
        print(f"The file at {input_file_path} was not found.")
    except Exception as e:
        print(f"An error occurred: {e}")

if __name__ == "__main__":
    input_file_path = '../data/input.txt'
    output_file_path = '../data/output.txt'
    read_and_write_file(input_file_path, output_file_path)

input.txt内容为：

Hello, World.

使用Code Runner运行程序时，报错The file at ../data/input.txt was not found.，如下图所示：

2. 解决方案

打开VSCode 设置settings，搜索file directory，然后在勾选 Code-runner: File Directory As Cwd

再次使用Code Runner可成功运行程序：
