如何解决更改Python模块上的权限，因此无需“ sudo”我的Python脚本调用
是否有一种方法可以重新配置我从中调用某些实用程序（即urlopen）的所有Python3模块，这样我就不必在不重建Ubuntu VM的情况下以“ sudo”开头我的Python3脚本调用了吗？ / p>
示例，我的脚本代码如下：
import socks
import socket
from urllib.request import urlopen
from time import sleep
from bs4 import BeautifulSoup
socks.set_default_proxy(socks.SOCKS5,"127.0.0.1",9050)
socket.socket = socks.socksocket
url_name1 = "http://www.google.com"
print("url name is : " + url_name1)
print("About to open the web page")
sleep(5)
webpage = urlopen(url_name1)
print("Web page opened successfully")
sleep(5)
html = webpage.read().decode("utf-8")
soup = BeautifulSoup(html,"html.parser")
print("HTML extracted")
sleep(5)
没有在命令前加上“ sudo”，输出如下所示：

解决方法
我向教授提出了这个问题，他建议我在Ubuntu VM上启用torsock后在python3命令前加“ torsocks”（在运行脚本之前必须先安装并配置tosocks）。
然后，从脚本中删除以下两个语句。
socks.set_default_proxy(socks.SOCKS5,"127.0.0.1",9050)
socket.socket = socks.socksocket
现在，当我输入“ torsocks python3
