我已经构建了一些debian软件包并将其放在主机上。我想将这些软件包安装在python脚本中。因此,我使用apt_pkg编写了安装功能,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,将安装软件包没有任何问题,但是使用此脚本会发生以下错误:
res = self.pkg_manager.do_install(log_file.fileno())apt_pkg。错误: E:内部错误,要安装的路径名不是绝对的 'myPackage_1.0.0_all.deb'
我已将.deb文件和Packages.gz放置在主机中名为“ debian”的目录中,并将以下行添加到了sources.list中:
deb http://my_host_address.com debian/
我不知道我的脚本有什么问题吗?
