在python中使用导入的模块会导致权限被拒绝错误
[英]Using a imported module in python result in permission denied error
问题描述
I'm trying to use a imported module (pylightning) in a python script that runs using apache under user www-data. 
我正在尝试在用户www-data下使用apache运行的python脚本中使用导入的模块（pylightning）。
The script gives a permission error when run via apache as user www-data: 当以用户www-data的身份通过apache运行时，脚本给出了权限错误：
File "/usr/local/lib/python3.4/dist-packages/lightning/lightning.py", line 69, in call
sock.connect(self.socket_path)
PermissionError: [Errno 13] Permission denied
To fix this I have intensively searched and found i needed to reinstall the module as www-data user: 为了解决这个问题，我进行了深入搜索，发现我需要以www-data用户身份重新安装该模块：
sudo pip3 uninstall pylightning
sudo -H -u www-data pip3 install pylightning
The script still runs smoothly from the CLI as regular user: 该脚本仍可以作为常规用户从CLI顺利运行：
$python3 index.py
Content-Type: text/html
<html><body>
etc...
But from apache (through a browser or from the command line as user www-data) still gives the same error: 但是从apache（作为用户www-data通过浏览器或从命令行）仍然给出相同的错误：
$sudo -u www-data python3 /var/www/html/index.py
Content-Type: text/html
<html><body>
Traceback (most recent call last):
File "/var/www/html/index.py", line 29, in <module>
print(rpc_interface.listpeers())
File "/usr/local/lib/python3.4/dist-packages/lightning/lightning.py", line 345, in listpeers
return self.call("listpeers", payload)
File "/usr/local/lib/python3.4/dist-packages/lightning/lightning.py", line 69, in call
sock.connect(self.socket_path)
PermissionError: [Errno 13] Permission denied
Anyone has any idea here? 有人在这里有想法吗？
Script source: 脚本来源：
#!/usr/bin/env python3
import hashlib
from lightning.lightning import LightningRpc
rpc_interface = LightningRpc("/home/pi/.lightning/lightning-rpc")
print ("Content-Type: text/html\n\n");
print ("</body></html>asd");
print(rpc_interface.listpeers())
the error triggers on this line: print(rpc_interface.listpeers()) 错误将在此行触发：print（rpc_interface.listpeers（））

验证www数据用户是否有权访问/home/pi/.lightning/lightning-rpc （包括父目录）。
