我想当我没有给予足够的关注时，我试图通过虚拟环境来搞乱我的Python安装。
python3 --version
Python 2.7.6
但当我检查垃圾箱时，我不确定情况是怎样的：
ls -lah /usr/bin/python3
lrwxrwxrwx 1 root root 9 Sep 21 2015 /usr/bin/python3 -> python3.4
这让我发疯，因为发生这种情况我无法正确使用 apt 。我收到 ASCII 错误，因为它使用了错误的解释器。
我很确定我把 pyvenv 或 venv 搞砸了，但我不确定是什么。帮助？
好吧，我运行dpkg -C并得到了一整堆半编译的包。主要是 python3 软件包，因为我尝试删除并重新安装它。我对它们运行 dpkg --configure 并得到一个给出此错误的结果：
Setting up python3-gi (3.12.0-1ubuntu1) ...
File "/usr/bin/py3compile", line 4
SyntaxError: Non-ASCII character '\xc2' in file /usr/bin/py3compile on line 4, but no encoding declared; see http://www.python.org/peps/pep-0263.html for details
dpkg: error processing package python3-gi (--configure):
subprocess installed post-installation script returned error exit status 1
Errors were encountered while processing:
python3-gi
我想，这个错误之前就出现过，就像我现在尝试安装其他软件包时出现的那样，但在堆栈跟踪中更靠后。
满的dpkg -C：

答案1
回顾所有内容，我发现问题是虚拟环境创建的 bin 目录实际上创建了到我的根 bin 目录的符号链接。
最后，我安装了不同的操作系统并从备份加载了我的文档。
