Python Selenium邮件采集程序在Sublime可运行但终端报错求助

我开发了一个基于Python Selenium的网站邮件采集程序，编写于Sublime Text编辑器中。程序在Sublime中通过Ctrl+B或「Build with python」执行时可正常运行，但在终端执行python3 harvest.py时，会在初始化Firefox驱动阶段触发错误。

程序代码 #

from selenium import webdriver
from selenium.webdriver import FirefoxOptions

class colors:
    RESET = '\033[0m'
    BOLD = '\033[1m'
    UNDERLINE = '\033[4m'
    BLACK = '\033[30m'
    RED = '\033[31m'
    GREEN = '\033[32m'
    YELLOW = '\033[33m'
    BLUE = '\033[34m'
    MAGENTA = '\033[35m'
    CYAN = '\033[36m'
    WHITE = '\033[37m'
    BOLDBLACK = '\033[1;30m'
    BOLDRED = '\033[1;31m'
    BOLDGREEN = '\033[1;32m'
    BOLDYELLOW = '\033[1;33m'
    BOLDBLUE = '\033[1;34m'
    BOLDMAGENTA = '\033[1;35m'
    BOLDCYAN = '\033[1;36m'
    BOLDWHITE = '\033[1;37m'

class App:
    def __init__(self):
        self.emails = []
        self.opts = FirefoxOptions()
        self.opts.add_argument("--headless")
        self.opts.binary_location = "/usr/bin/firefox"
        self.driver = webdriver.Firefox(options=self.opts)
        self.read_urls()
        self.driver.close()
    def read_urls(self):
        urls = [ "https://wertweoritwoertiwoerit.com/", "https://rwteirtwertwertwertwe.com/" ]
        for url in urls:
            self.scan(url)
        #print(self.emails)
    def scan(self,url):
        self.driver.get(url)
        source_code = self.driver.page_source
        body = self.driver.find_element("css selector", "body")
        visible_text = body.text
        edited_visible_text = visible_text.replace("\n", " ")
        array = edited_visible_text.split(' ')
        for string in array:
            if "@" in string:
                self.emails.append(string)
                print(""+colors.BOLDBLUE + f"[+]{string}"+colors.RESET)
if __name__ == "__main__":
    main = App()

终端执行报错信息 #

已完成的排查动作 #

• 配置了Firefox二进制文件路径
• 设置了geckodriver路径并尝试添加相关配置
• 尝试查找geckodriver日志文件但未找到

排查方向与解决方案 #

1. 确认Python环境一致性 #

Sublime和终端可能使用不同的Python环境，导致依赖版本差异：

• 在Sublime中执行代码import sys; print(sys.executable)，获取其使用的Python路径
• 在终端执行which python3，对比两者路径
  如果路径不同，可选择：
  • 在终端切换到Sublime使用的Python环境运行脚本（比如用/path/to/sublime/python harvest.py）
  • 在终端的Python环境中重新安装依赖：pip3 install selenium

2. 验证geckodriver与Firefox版本兼容性 #

版本不匹配是常见报错原因：

• 终端执行firefox --version和geckodriver --version，记录版本号
• 确保两者版本兼容（最新版geckodriver通常适配最新版Firefox，旧版本需对应匹配），不兼容则升级或降级其中一方

3. 明确指定geckodriver路径 #

在代码中直接指定geckodriver的完整路径，避免环境变量问题：

from selenium import webdriver
from selenium.webdriver import FirefoxOptions
from selenium.webdriver.firefox.service import Service

# ...

class App:
    def __init__(self):
        self.emails = []
        self.opts = FirefoxOptions()
        self.opts.add_argument("--headless")
        self.opts.binary_location = "/usr/bin/firefox"
        # 添加这行指定geckodriver路径
        service = Service(executable_path="/path/to/geckodriver")
        self.driver = webdriver.Firefox(service=service, options=self.opts)
        self.read_urls()
        self.driver.close()

4. 启用geckodriver日志定位问题 #

修改代码生成日志文件，查看Firefox启动失败的具体原因：

service = Service(executable_path="/path/to/geckodriver", log_path="geckodriver.log")
self.driver = webdriver.Firefox(service=service, options=self.opts)

运行脚本后，查看当前目录下的geckodriver.log，里面会包含详细的启动错误信息。

5. 调整无头模式参数 #

部分Linux环境下，无头模式需要额外参数才能正常运行：

self.opts.add_argument("--headless=new")  # 替代旧的--headless参数
self.opts.add_argument("--disable-gpu")
self.opts.add_argument("--no-sandbox")  # 解决沙箱权限问题
self.opts.add_argument("--disable-dev-shm-usage")  # 解决临时空间不足问题
