Question

我有一些进口：

#!/usr/bin/env ruby

require 'openssl'

data = File.open('blob', 'r:ASCII-8BIT').read
c = OpenSSL::Cipher.new('AES-128-ECB')
c.decrypt
c.key = 'M02cnQ51Ji97vwT4'
o = ''.force_encoding('ASCII-8BIT')
data.bytes.each_slice(16) { |s| o += c.update(s.map(&:chr).join) }
o += c.final
File.open('blob.jpg', 'w') { |f| f.write(o) }

引发错误（可能是2）：

gi.require_version('Gtk', '3.0')
from gi.repository import Gtk
from gi.repository import Gdk, GdkPixBuf

我注意到的是，在gi的importer.py中，repository.enumerate_versions（namespace）为GdkPixBuf返回[]（因此会引发错误）。

其他导入会返回一些内容：

WARNING **: Error retrieving accessibility bus address: org.freedesktop.DBus.Error.ServiceUnknown: The name org.a11y.Bus was not provided by any .service files
Traceback (most recent call last):
  File "<frozen importlib._bootstrap>", line 2158, in _find_spec
AttributeError: 'DynamicImporter' object has no attribute 'find_spec'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "camerapython.py", line 10, in <module>
    from gi.repository import Gdk, GdkPixBuf
  File "/usr/lib/python3/dist-packages/gi/importer.py", line 53, in find_module
    'introspection typelib not found' % namespace)
ImportError: cannot import name GdkPixBuf, introspection typelib not found

如果需要，我的dist是Raspbian（Raspberry Pi 3）。

Answer 1

你导致Pixbuf错误，应该是

from gi.repository import Gdk, GdkPixbuf

GdkPixBuf的Python导入说“找不到内省类型库”
