python - 使用 Python gnupg 包，我收到错误 "Homedir ' 'C :/Users/. 。 .' needs read/write permissions"

Question

我在 Anaconda 中运行 Windows 7 和 Python 3.6.1 版。我使用 pip install gnupg 安装了 python 包 gnupg。

我从 ftp://ftp.gnupg.org/gcrypt/binary/ 下载了 gnupg Windows 可执行文件 2.1.23| .

当我使用下面两行中的任何一行运行代码时，它会失败并出现以下错误。

import gnupg

gpg = gnupg.GPG(binary='C:/Program Files (x86)/GnuPG/bin/gpg.exe',
               homedir='C:/Users/Alex/Desktop/SFTP Connection')

# gpg = gnupg.GPG(binary='C:/Program Files (x86)/GnuPG/bin/gpg.exe')

但是，当我使用这两行中的任何一行运行 Python 代码时，它都会失败。

import gnupg
# gpg = gnupg.GPG(homedir='C:/Program Files (x86)/GnuPG')
gpg = gnupg.GPG(homedir='C:/Program Files (x86)/GnuPG/bin')

RuntimeError: Homedir ''C:/Users/Alex/Desktop/SFTP Connection'' needs read/write permissions

我运行了以下两个命令并验证了该文件夹具有读写权限。

>>> os.access('C:/Users/Alex/Desktop/SFTP Connection', os.W_OK)
True
>>> os.access('C:/Users/Alex/Desktop/SFTP Connection', os.R_OK)
True
>>>

关于新权限报错，我猜其实是gnupg的bug，我have submitted a patch .
