Ubuntu dpkg错误：pycompile:未找到

当我尝试使用上述命令删除mysql时，出现以下错误：

sudo apt-get remove --purge mysql-server mysql-client mysql-common

如何解决此问题？

尝试以下方法：

首先删除不需要的包：

Reading package lists... Done
Building dependency tree       
Reading state information... Done
Package 'mysql-client' is not installed, so not removed
The following package was automatically installed and is no longer required:

  php5-mysqlnd

Use 'apt-get autoremove' to remove it.

The following extra packages will be installed:

  mysql-server-core-5.5 php5-mysqlnd python-aptdaemon

 python-aptdaemon.gtk3widgets python3-aptdaemon python3-aptdaemon.gtk3widgets

  python3-aptdaemon.pkcompat python3-uno python3-update-manager
  ubuntu-drivers-common update-manager

The following packages will be REMOVED:
  libdbd-mysql-perl* libmysqlclient18* mysql-client-5.5* mysql-common*
  mysql-server* mysql-server-5.5* php5-mysql* phpmyadmin*

The following NEW packages will be installed:
  php5-mysqlnd

The following packages will be upgraded:

  mysql-server-core-5.5 python-aptdaemon python-aptdaemon.gtk3widgets

  python3-aptdaemon python3-aptdaemon.gtk3widgets python3-aptdaemon.pkcompat

  python3-uno python3-update-manager ubuntu-drivers-common update-manager

清除检索到的包文件的本地存储库

sudo apt-get autoremove

删除包（未安装mysql客户端）：

py3compile:未找到

py3compile

命令是

python3minimal

包的一部分，该包似乎已损坏

要解决此问题，请尝试以下操作：

• 通过以下方式更正已断开依赖关系的系统：

  sudo apt-get remove mysql-server mysql-common
  

• 通过以下方式重新配置所有未打包但未配置的包：

  sudo apt-get  -f install
  

• 如果上述方法无效，请尝试通过以下方式重新安装

  python3 minimal

  软件包：

  sudo dpkg --configure -a
  

  或者运行：

  sudo apt install -f --reinstall python3-minimal
  

  或通过以下方式从文件下载并安装：

  apt-get download python3-minimal
  sudo dpkg -i *python3*.deb
  sudo apt install -f
  

---

然后确保

py3compile

和

py3clean

命令可以运行，并且可以从

PATH

变量访问这些命令。

尽管py3compile和py3clean存在于/usr/bin/中，但我的Lubunutu 16.10 shell（tcsh）一直抱怨py3compile不存在。经过数小时的挫折，我发现pycompile中的第一行是：

/usr/bin/env python

或者类似的东西，在我的系统中引用了Python2.7。使用以下命令将其更改为指向Python 3：

/usr/local/bin/python3

突然使py3compile可见

事实证明，shell所说的py3compile即使在其路径中也不存在，或者在py3compile引用Python2.7时直接使用“/usr/bin/py3compile”执行。shell甚至没有抱怨Python版本或任何东西，它只是声称py3compile本身并不存在

---

我陷入这种混乱是因为我想删除并重新安装Python3.5，在这样做之后，我发现仍然有一个Python3，然后我发现它来自一个Pythonminimal，我试图删除并重新安装它。pythonmiminal不会重新安装，即使在我尝试了在网络上找到的所有东西和每个包管理器之后。他们都会抱怨Py3文件丢失。现在我发现了py3compile的这个补丁。

啊，是的。Debian软件包管理的古老“第22条军规”。它归结为Debian，这取决于

py3compile

作为

libpython3.x

包的一部分，而该包也提供了

py3compile

；这是不可能的

我也被这件事折磨了，因为我也删除了整个/usr/[/local]/lib/python3*目录，所以无法让

py3compile

再次工作

一旦完成，Debian软件包管理工具中的任何内容都不能帮助您回到一个正常工作的Python3环境。你必须做肉丸手术

在Debian中重建Python3需要三件关键的事情：

• 还原

  py3compile

  script（对于大多数人来说，您已经有了这个）
• 恢复libpython3.7
• 还原python二进制文件

可以从另一个正在工作的Debian主机/系统重新复制/usr[/local]/lib目录。但这一次，我将详细说明在所讨论的坏主机中的步骤（好像您没有另一个工作主机）

步骤1-下载软件包 下载受影响的Debian软件包：

cd/tmp
apt获取下载libpython3.7-minimal
apt获取下载python3.7-minimal
apt get下载python3 minimal（这很重要）
apt获取下载libpython3.7-stdlib
apt获取下载python3.7

步骤2-清理 清理旧东西

rm-rf/usr[/local]/lib/python3.7*
rm-rf/usr[/local]/bin/python3.7*
更新备选方案--删除python3/usr[/local]/bin/python3.7
hash-r#删除缓存的python3二进制路径

步骤3-从包中提取文件 让我们提取缺少的

py3compile

cd/tmp
dpkg deb-x蟒蛇3-minimal_3.7.3-1_amd64.deb缺失
dpkg deb-x蟒蛇3.7-minimal_3.7.3-2_amd64.deb缺失
dpkg deb-x libpython3.7-minimal_3.7.3-2_amd64.deb缺失
dpkg deb-x libpython3.7-stdlib_3.7.3-2_amd64.deb缺失
dpkg deb-x蟒蛇3.7_3.7.3-2_amd64.deb缺失

步骤3 在根文件系统上手动安装

cd/tmp/缺失
ls-lR/tmp/missing#如果你想覆盖你的硬盘
sudo cp-rpfv/tmp/missing/*/

步骤4-核查 启动Python3

python3
Python 3.7.3（默认值，2019年4月3日，05:39:12）
linux上的[GCC 8.3.0]
有关详细信息，请键入“帮助”、“版权”、“信用证”或“许可证”。
>>>

测试导入和显示版本

导入系统 >>>打印（系统版本信息） 系统版本信息（主版本=3，次版本=7，微版本=3，版本级别=final，序列号=0） >>> >>>退出 第五步-清洁自己

rm-rf/tmp/缺失

步骤6-通过Debian APT正式重新安装Python

dpkg-s-a | grep reinstreq
#任何清单也需要与python3一起重新安装
apt get安装--重新安装python3

最有可能的是，您得到了许多处于“reinstreq”状态的软件包

apt获取自动清理
自动记忆
#（许多软件包未能安装）

此时，您必须手动重新安装

apt get autoremove

中列出的每一项

apt获取安装--修复损坏--重新安装

最后一步-重新安装受影响的半状态Debian软件包 让我猜猜，您得到了以下错误：

sudo dpkg -i python3-minimal_*.deb

我会告诉你，你的

/etc/apt/sources.list中可能有一个较新的Debian版本。有一段时间，它完全失败了（糟糕），并从
sources.list
文件中删除了这个较新的版本（努力恢复到“稳定”的版本）：这对我来说不是一件不可恢复的事情，只是你把Debian软件包数据库弄得有点乱。。。相当粗鲁

最后一步的解决需要
sudo dpkg -i python3-minimal_*.deb
