What I have installed, following the solution at VIM + JSLint?:

我在VIM + JSLint的解决方案下安装了什么?

• Vundle
• Vundle
• node.js
• node . js
• Node Package Manager
• 节点包管理器
• jshint, globally
• jshint,全球
• Syntastic installed through Vundle (Used the :BundleInstall command inside Vim to make sure Syntastic was installed.)
• 通过Vundle安装Syntastic(使用:Vim内的BundleInstall命令以确保安装了Syntastic)。

.vimrc:

. vimrc:

set nocompatible               " be iMproved
filetype off                   " required!

set rtp+=~/.vim/bundle/vundle/
call vundle#rc()

" let Vundle manage Vundle
" required! 
Bundle 'gmarik/vundle'

" My Bundles here:
Bundle 'scrooloose/syntastic'

filetype plugin indent on     " required! 

let g:syntastic_enable_signs=1
let g:syntastic_auto_jump=1

looking for installed executables:

寻找安装可执行文件:

$ which gjslint
$ which jslint
$ which jsl
$ which jshint
/home/fernando/local/node/bin/jshint
$ 


$ echo $PATH

>/home/fernando/local/bin:/home/fernando/local/node/bin:/home/fernando/node_modules/.bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games

$ jshint test.js

test.js: line 3, col 1, 'blbla' is not defined.
test.js: line 4, col 1, 'x' is not defined.
test.js: line 4, col 5, 'nonono' is not defined.
test.js: line 6, col 1, 'a' is not defined.
test.js: line 7, col 1, 'b' is not defined.
test.js: line 8, col 5, 'a' is not defined.
test.js: line 8, col 10, 'b' is not defined.
test.js: line 8, col 7, Expected '===' and instead saw '=='.

测试。第3行，第1行，“blbla”没有定义。测试。第4行，第1行，'x'没有定义。测试。第4行，第5行，“nonono”没有定义。测试。第6行，第1行，'a'没有定义。测试。第7行，第1行，'b'没有定义。测试。第8行，第5行，“a”没有定义。测试。第8行，第10行，'b'没有定义。测试。js:第8行，第7行，预期'=='，改为'= '。

8 errors

8个错误

$ vi test.js -- no error message shown

:SyntasticEnable -- Vim exits and restarts, opening the same file, but still no message

:w -- still no error message

:Errors -- the location list opens but it is empty

Both jshint and Syntastic seem to be installed, but something is probably missing. What would it be?

jshint和Syntastic似乎都安装了，但可能缺少了一些东西。那会是什么?

Here is a more updated info, there is a configuration to associate a file extension to a checker,
in your .vimrc

这里有一个更新的信息，有一个配置，可以将文件扩展名关联到一个检查器，在您的.vimrc中。

let g:syntastic_javascript_checkers = ['jshint']

Also to get info about what's going on run this command in vim

还要了解在vim中运行该命令的情况。

:SyntasticInfo

And you'll get an output similar to this:

你会得到一个类似的输出:

Syntastic info for filetype: javascript  
Available checkers: gjslint jshint  
Currently active checker(s): gjslint  
Press ENTER or type command to continue

I just had this same problem. Turns out, Syntastic looks for jsl (JSLint) before it looks for jshint. If you have both installed, you'll likely be misled. I moved jsl somewhere not in my PATH, and jshint was detected just fine.

我也有同样的问题。原来，jsl (JSLint)在寻找jshint之前，要寻找Syntastic。如果你都安装了，你可能会被误导。我移动了jsl，而不是在我的路径中，jshint被检测到很好。

I struggled with this issue for days and SyntasticInfo would not recognize jshint as an available checker even after i added let g:syntastic_javascript_checkers['jshint'] to my .vimrc. I am using Ubuntu 15.04 and I followed this tutorial to install nvm, nodejs, and jshint on Ubuntu. After I did that I discovered that if I removed the line filetype plugin indent on from my .vimrc then opened a .js file everything worked perfectly! To summarize...

我在这个问题上花了好几天的时间，而SyntasticInfo甚至在我添加了让g:syntastic_javascript_checkers['jshint']到my .vimrc之后，也不承认jshint是一个可用的检查器。我使用Ubuntu 15.04，我跟随本教程安装了nvm、nodejs和jshint。在我做了这个之后，我发现如果我从我的.vimrc上删除了line filetype插件，那么打开一个.js文件，一切都很顺利!总结……

1. follow the tutorial linked above
2. 遵循上面的教程链接。
3. add ~/.nvm/<version_number>/bin to path in .bashrc
4. 添加~ /。nvm/ /bin to path in .bashrc。
5. remove filetype plugin indent on from .vimrc
6. 从.vimrc删除文件类型插件。
7. add let g:syntastic_javascript_checkers['jshint'] to .vimrc
8. 添加让g:syntastic_javascript_checkers['jshint']到.vimrc。
9. :so % inside vim
10. 所以在vim %
11. open a .js file
12. 打开一个. js文件
13. add filetype plugin indent on back to your .vimrc
14. 在你的。vimrc上添加文件类型插件。
15. everything magically works now
16. 现在一切都神奇地工作
