ModuleNotFoundError: No module named 'CommandNotFound'

错误来源：

Ubuntu18系统，安装最新版python后就出现如下错误：

ModuleNotFoundError: No module named 'CommandNotFound'
   
   
   
   

而且，pip install时，还是出现了这个错误：

   
   
   
   

    
    
    
    

     
     
     
     

      
      
      
      

     
     
     
     
     
     
     
     

      
      
      
      

       
       
       
         File

           output=stdout, stderr=stderr)
      
      
      
      
     
     
     
     
    
    
    
    

     
     
     
     

      
      
      
      

     
     
     
     
     
     
     
     

      
      
      
      

       
       
       
       subprocess.CalledProcessError: Command 
       
       
       
       '('lsb_release
       
       
       
       ', '-a
       
       
       
       ')' returned non-zero 
       
       
       
       exit status 1.
      
      
      
      
     
     
     
     
   
   
   
   
   
   
   
   

终端运行lsb_release -a则是报错：

ModuleNotFoundError: No module named 'lsb_release'
   
   
   
   

---------------------------------------------------------------

解决方案：

找到lsb_release.py文件和CommandNotFound目录，把它们拷贝到报的错误中subprocess.py所在文件夹

命令如下：

   
   
   
   

    
    
    
    

     
     
     
     

      
      
      
      

     
     
     
     
     
     
     
     

      
      
      
      

       
       
       
       sudo find / -name 
       
       
       
       'lsb_release.py'
      
      
      
      
     
     
     
     
    
    
    
    

     
     
     
     

      
      
      
      

     
     
     
     
     
     
     
     

      
      
      
      

       
       
       
       # result:

       python -V
