我正在使用python-gnupg在烧瓶应用程序中连接gpg。该模块与我的应用程序的其余部分一起安装在virtualenv中。在运行时我收到一个500内部服务器错误，异常是：烧瓶应用程序找不到gpg
File "./myproject/views/settings.py", line 257, in settings_keys_add
gpg = gnupg.GPG()
File "/home/puse/myproject/myproject/lib/python3.5/site-packages/gnupg.py", line 733, in __init__
p = self._open_subprocess(["--version"])
File "/home/puse/myproject/myproject/lib/python3.5/site-packages/gnupg.py", line 786, in _open_subprocess

raise child_exception_type(errno_num, err_msg)
FileNotFoundError: [Errno 2] No such file or directory: 'gpg'
GPG已安装并正常工作：
[email protected] ~/puse> which gpg
/usr/bin/gpg
[email protected] ~/puse> gpg --gen-key

我也可以得到它从Python中的virtualenv内工作：

>>> import gnupg
>>> gpg = gnupg.GPG()
>>> a = gpg.scan_keys("/opt/keys/2a798434-ebb3-4dc6-9f76-fd46f0cce6fa")
我怀疑它与运行该应用程序的用户有关系，但该应用程序正在我的用户下运行，但组设置为www-data。我已经通过运行ps证实了这一点。
