Question

我知道这种问题已经问过很多次了。我什至发现了几乎相同的问题：How to use pip3 for python 3.6 instead of python 3.5? 但是我仍然没有解决我的问题。我正在使用os x。

我有python的三个版本：2.7、3.6和3.7。

{  
   "ORGANIZATION":[  
      {  
         "   id":101,
         "category_name":"Organization 1",
         "description":" ",
         "WING ":[  
            //this is the category children which can also be a subcategory            {  
               "id":122,
               "category_name":"wing 1",
               "description":"",
               "FLOOR":[  
                  {  
                     "id":111,
                     "category_name":"floor 1"
                  }
               ]
            },
            {  
               "id":555,
               "category_name":"wing 2",
               "description":""
            },
            {  
               "id":222,
               "category_name":"wing 3",
               "description":""
            }
         ]
      },
      {  
         "id":11111,
         "category_name":"organization 2",
         "description":"",
         "WING":[  
            {  
               "id":4545,
               "category_name":"wing 1",
               "description":""
            },
            {  
               "id":252,
               "category_name":"wing 2",
               "description":"",
               "FLOOR":[  
                  {  
                     "id":131,
                     "category_name":"floor 1",
                     "description":""
                  }
               ]
            },
            {  
               "id":2526,
               "category_name":"Wing 3 ",
               "description":"",
               "FLOOR":[  
                  {  
                     "id":87,
                     "category_name":"floor 2",
                     "description":""
                  },
                  {  
                     "id":565,
                     "category_name":"floor 3",
                     "description":"",
                     "ROOM":[  
                        // here is an example of a child that is a sub-category also                        {  
                           "id":555,
                           "category_name":"room 1",
                           "description":""
                        },
                        {  
                           "id":584,
                           "category_name":"room 2",
                           "description":""
                        },
                        {  
                           "id":77,
                           "category_name":"room 3",
                           "description":""
                        }
                     ]
                  }
               ]
            }
         ]
      }
   ]
}

但如果我这样做

python --version
Python 2.7.10

python3 --version
Python 3.7.4

我不知道为什么pip3指向3.6而不是3.7（而python3给我3.7）

如果我愿意

pip3 --version
pip 9.0.1 from /Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages (python 3.6)

我有

python3 
import site; site.getsitepackages()

PIP3指向python 3.6而不是3.7。如何使它指向python 3.7？

我尝试将python3添加到路径，但无济于事。我不想卸载python 3.6。

Answer 1

养成使用以下内容的习惯；

python -m pip install <package> # and you will be sure to have the package attached with the right version of python

例如：-

$ python3 -m pip install requests

Answer 2

我最终在bash_profile中使用了它

alias pip3='/usr/local/bin/python3 -m pip'

Answer 3

$ which pip3
/usr/bin/pip3 

$ nano /usr/bin/pip3

在文件的第一行，您应该看到

#!/usr/bin/python3

只需将其更改为所需的python版本即可。

#!/usr/bin/python3.7
or
#!/usr/bin/python3.8

保存。完成！

PIP3与错误的python版本相关
