gpg：decrypt_message失败：eof

Question

我正在使用Python v3.6.5（Anaconda），python-gnupg v2.3.1，gpg.exe v1.4.22，并且在解密时出现以下错误：

  

错误：root：gpg：无法创建D：/ folder / flder / pgb \ D：/folder/flder/pgbsecring.gpg.lock'：
      gpg：密钥块资源D：/ folder / flder / pgb \ D：/folder/flder/pgbsecring.gpg'：一般错误
      gpg：无法创建D：/ folder / flder / pgb \ D：/folder/flder/pgbpubring.gpg.lock'：
      gpg：关键块资源D：/ folder / flder / pgb \ D：/folder/flder/pgbpubring.gpg'：一般错误
      gpg：找不到有效的OpenPGP数据。
      [GNUPG：] NODATA 1
      [GNUPG：] NODATA 2
      gpg：decrypt_message失败：eof

下面是我的代码：

import gnupg
gpg=gnupg.GPG(homedir='D:/folder/flder/pgb',binary='C:/Users/Anaconda3/Lib/GNU/gpg.exe')
status = pgp.decrypt(gpg, res_files['fname'], gpcnf['passphrase'], outfile)

with open(file, 'rb') as f:
        status = gpg.decrypt_file(f, passphrase=passphrase, output=outfile)
