我已经构建了一些 debian 软件包并将它们放在我的主机上。我想在 python 脚本中安装这些包。因此,我使用 apt_pkg 编写了安装函数,如下所示:
#!/usr/bin/env python
# -*- coding: utf-8 -*-
import apt
import apt_pkg
import sys
class my_pkg_manager:
def __init__(self):
apt_pkg.init()
self.cache = apt_pkg.Cache()
self.sources = apt_pkg.SourceList()
self.pkg_records = apt_pkg.PackageRecords(self.cache)
self.depcache = apt_pkg.DepCache(self.cache)
self.pkg_manager = apt_pkg.PackageManager(self.depcache)
self.fetcher = apt_pkg.Acquire()
def find_my_package(self):
for pkg in self.cache.packages:
if len(pkg.version_list)>0:
package_site = pkg.version_list[0].file_list[0][0].site
if package_site == 'my_host_address.com':
if pkg.name == 'my_pkg_name':
return pkg
return None
def install_package(self, pkg):
self.depcache.mark_install(pkg)
self.sources.read_main_list()
self.pkg_manager.get_archives(self.fetcher, self.sources,
self.pkg_records)
log_file = open('install_log','w')
res = self.pkg_manager.do_install(log_file.fileno())
if res == self.pkg_manager.RESULT_COMPLETED:
print('result completed!')
elif res == self.pkg_manager.RESULT_INCOMPLETE:
print('result incomplete!')
else:
print('result failed!')
def run(self):
my_pkg = self.find_my_package()
if my_pkg != None:
self.install_package(my_pkg)
else:
print('Can't find package!')
if __name__ == '__main__':
my_package_manager = my_pkg_manager()
my_package_manager.run()
如果我使用 apt-get install,安装包没有任何问题,但是使用这个脚本会出现以下错误:
res = self.pkg_manager.do_install(log_file.fileno()) apt_pkg.Error: E:Internal Error, Pathname to install is not absolute 'myPackage_1.0.0_all.deb'
我已将 .deb 文件和 Packages.gz 放在主机中名为“debian”的目录中,并将以下行添加到我的 sources.list :
deb http://my_host_address.com debian/
我不知道我的脚本有什么问题?
