Python 写入临时文件

import tempfile import subprocess import os custom_tmp_dir = r"E:\js_tmp" # 你想放临时 js 的目录 os.makedirs(custom_tmp_dir, exist_ok=True) js_code = "console.log(123);" with tempfile.NamedTemporaryFile( mode='w', suffix='.js', dir=custom_tmp_dir, # 👈 关键 delete=False, encoding='utf-8' ) as f: f.write(js_code) js_path = f.name result = subprocess.run( ['node', js_path], capture_output=True, text=True ) print(result.stdout) os.remove(js_path)
