如何将Syntastic设置为python3检查器而不是python2 [英] How to setup Syntastic as python3 checker instead of python2

问题描述

在MacVim中，我将以下代码另存为test.py

In MacVim, I save following code as test.py

print "Hello world! python2"

，显然是python3的错误，但是 我运行:w保存文件后，没有错误信息出现， 以下是〜/.vimrc的一部分，全部与Syntastic有关:

, which is apparently wrong with python3, but after I run :w to save the file, there is no error message for it, Following is a part of ~/.vimrc, which is all about Syntastic:

" Syntastic                                                                     
"" Recommended settings                                                         
set statusline+=%#warningmsg#                                                   
set statusline+=%{SyntasticStatuslineFlag()}                                    
set statusline+=%*                                                              
let g:syntastic_always_populate_loc_list = 1                                    
let g:syntastic_auto_loc_list = 1                                               
let g:syntastic_check_on_open = 1                                               

"" Display checker-name for that error-message                                  
let g:syntastic_aggregate_errors = 1        

"" I use the brew to install flake8                                             
let g:syntastic_python_checkers=['flake8', 'python3']

当我在终端中运行test.py时，如何使Syntastic检测此类错误:

How to make Syntastic detect this type of error as I run test.py in Terminal:

NingGW:Desktop ninggw$ python3 test.py
  File "test.py", line 1
    print "Hello world! python2"
                               ^
SyntaxError: Missing parentheses in call to 'print'

以下是:SyntasticInfo所说的:

Following is what :SyntasticInfo said:

Syntastic version: 3.8.0-10 (Vim 800, Darwin, GUI)
Info for filetype: python
Global mode: active
Filetype python is active
The current file will be checked automatically
Available checkers: flake8 python
Currently enabled checker: flake8
Press ENTER or type command to continue

推荐答案

flake8是Python软件包.它使用Python的内置功能来解析代码，因此它接受所属的Python版本的语法.

flake8 is a Python package. It uses Python's built-in facilities to parse code, so it accepts syntax for the Python version that it belongs to.

如何为python3安装安装它取决于安装本身的安装方式-除非您使用pip 很好.

How to install it for your python3 installation depends on how that installation itself was installed - unless you're fine with using pip.
