Python3
python3指向python2.7.6
我想當我沒有給予足夠的關注時，我試圖弄亂虛擬環境，從而提升了我的 python 安裝。
python3 --version Python 2.7.6但是當我檢查垃圾箱時，我不確定這是怎麼回事：
ls -lah /usr/bin/python3 lrwxrwxrwx 1 root root 9 Sep 21 2015 /usr/bin/python3 -> python3.4這讓我發瘋，因為發生這種情況我無法正確使用 apt 。我收到 ASCII 錯誤，因為它使用了錯誤的解釋器。
我很確定我用 pyvenv 或 venv 搞砸了，但我不確定是什麼。幫助？
好的，我跑了
dpkg -C，得到了一整包半編譯的包。大多數是 python3 包，因為我試圖刪除並重新安裝它。我在它們上執行了 dpkg –configure 並找到了一個給出此錯誤的錯誤：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，這個錯誤以前出現過，就像我現在嘗試安裝其他軟體包時出現的那樣，但在堆棧跟踪中更遠了。

which python3返回
/usr/bin/python3和
dpkg -S /usr/bin/python3 python3-minimal: /usr/bin/python3啊哈！但這意味著什麼？

回顧一切，我發現問題是虛擬環境創建的 bin 目錄實際上創建了指向我的根 bin 目錄的符號連結。
最後，我安裝了一個不同的作業系統並從備份中載入了我的文件。
