Question

im使用python 3，但需要安装python 2进行测试。卸载python2后，如果我运行python 3代码，则会出现以下错误：

$( "#combobox" ).combobox({
         select: function(event, ui) {
           console.log("Selected");
            // Event handling code goes here.
         } // selected
      });

这是我的代码：

如您所见，没有任何东西会使此错误出现。如果我运行一个简单的hello world程序，一切正常。

我真的不知道为什么，但是，在sys.flags中没有名为utf8_mode的属性。如果要查看和比较编码，请尝试：

> vue.esm.js:1741 ReferenceError: body is not defined
>     at o.eval (eval at ko (vue.esm.js:10680), <anonymous>:3:642)
>     at o.t._render (vue.esm.js:4544)
>     at o.<anonymous> (vue.esm.js:2788)
>     at je.get (vue.esm.js:3142)
>     at new je (vue.esm.js:3131)
>     at vue.esm.js:2795
>     at o.hn.$mount (vue.esm.js:8540)
>     at o.hn.$mount (vue.esm.js:10939)
>     at init (vue.esm.js:4137)
>     at vue.esm.js:5608

或者也许：

if sys.getdefaultencoding() == 'utf-8':
    continue

我不确定自己在做什么，因为没有代码，所以这是我所能做的限制。

编辑：错误似乎出在python的lib文件夹内的_bootlocale.py文件上。我认为从python 2.x来的一些残余被遗留下来，并且在返回到3.x之后没有被覆盖或更新

我认为先卸载再删除整个python文件夹，然后检查local_variables以防万一，在重新安装python 3.x之前可以解决此问题，尽管我不确定是否会解决。

安装和卸载Python2后出现错误
