Python调用ESLint检查临时.js文件时遭遇忽略问题

我需要对生成的.js内容做ESLint基础合理性检查，用Python的subprocess模块调用ESLint，并用tempfile创建临时.js文件执行检查。但即使添加了--no-ignore参数，ESLint仍提示该临时文件被忽略，断言验证失败。将文件写入当前目录时，ESLint可正常工作，推测是tempfile生成的路径导致被忽略。

代码示例 #

import subprocess
import tempfile
import os

# 创建临时文件、执行ESLint验证并清理
def run_eslint_validation(content):
    with tempfile.NamedTemporaryFile(delete=False, suffix=".js", mode='w') as tmp:
        tmp.write(content)
        js_file_path = tmp.name

    cmd = [
        'eslint',
        '--no-config-lookup',
        '--no-ignore',
        '--rule', 'semi: [error, always]', # 强制要求分号
        js_file_path
    ]

    # 执行验证
    try:
        result = subprocess.run(cmd, capture_output=True, text=True)
        print("CMD:", cmd)
        print("STDOUT:", result.stdout)
        return result.returncode == 0
    finally:
        # 删除临时文件
        os.remove(js_file_path)

assert(run_eslint_validation("const x = 10")) == False, "ESLint验证失败"

报错信息 #

可行方案（写入当前目录） #

将文件写入当前目录时，ESLint可正常工作，代码如下：

js_file_name = f"{uuid.uuid4()}.js"
    js_file_path = os.path.join('.', js_file_name)

    # 将JavaScript内容写入文件
    with open(js_file_path, 'w') as js_file:
        js_file.write(content)
