答案1
这是由于以下错误造成的：
File "/usr/bin/pyclean", line 63
except (IOError, OSError), e:
最有可能的原因是它期望的是 python2.x 而不是 python3。
您必须链接/usr/bin/python到适当的版本。如果我没记错的话，/usr/bin/python --version将输出 3.x，因此您可能需要创建指向 python2.x 的符号链接：
ls -la /usr/bin/python # you will see if there's a symlink towards some other file
rm /usr/bin/python # only if it is a symlink!
ln -s /usr/bin/python2.x /usr/bin/python
2.x你的 python 版本在哪里？
或者，更简单，但您需要同时安装 2.x 和 3.x：
sudo update-alternatives --config python
