我只是偶然发现了同样的问题，所以我将把它发生的原因留给我。
我们使用pip将主pipe安装到全局path（而不是virtualenv），这意味着我们正在运行最新版本。 然而，从服务器维护的angular度来看这是不可取的，所以我们在Apt中切换了旧版本。
pip uninstall不能自行清除后，将脚本/日志留在所有以下目录中：
我build议做以下search并手动删除对supervisor-3.0a12的所有引用：
sudo find / -iname "*supervisor*"
有趣。 这是目前不知道的错误。 在安装的时候，你应该会收到一个不同的错误，因为在这个版本的Ubuntu中，当前主pipe是被破坏的。 查看错误报告： https ： //bugs.launchpad.net/ubuntu/+source/supervisor/+bug/777862
主pipe可能是previsouly安装，然后删除，但没有清除（所以configuration文件没有被删除）。 稍后，某人手动移除configuration文件。 现在，当您重新安装时，默认情况下它不会replaceconfiguration文件，因为dpkg永远不会覆盖您所做的configuration更改，并且删除configuration文件被视为configuration更改。 你可以专门告诉dpkg来replace丢失的conffiles，像这样：
aptitude -o DPkg::Options::='--force-confmiss' reinstall supervisor
或者，您可以在安装之前清除软件包，说您不想保存您的configuration文件。
