Sublime是我最愛的寫程式碼神器。最近看網上配置sublime為python IDE的文章時，看到很多人推薦使用Pylinter這個外掛。仔細研究了一番，這個外掛主要是用來檢查程式碼格式的，從而規範化python程式設計師的編碼規範。

但是由於我經常開發的專案是Django，而Django各種ORM把pylint搞得是暈頭轉向。比如，經常會出現這樣一個錯誤：

Class 'xxx' has no 'objects' member

這個其實就是pylint對Django支援不好的原因。看StackOverFlow大神說需要使用一個“更懂Django”的外掛，叫做pylint-django

Ubuntu使用如下命令安裝：

sudo pip install pylint-django

然後使用的時候這麼使用，在命令列

pylint -E --load-plugins=pylint_django xxx.py

可以看到還是有效果的。加了pylint_django的外掛以後就不輸出錯誤。但是當在sublime pylint中配置load_plugins時，就成了這樣：

出現pylint_plugin_utils.NoSuchChecker錯誤。。

好吧，根據逐一排查，最終定位到原來問題的根源在於/usr/local/lib/python2.7/dist-packages/pylint_plugin_utils/__init__.py檔案中的一個if判斷句

臨時解決辦法：

把__init__.py檔案中的get_checker函式中的

if isinstance(checker, checker_class):

替換為

if checker.__class__.__name__ == checker_class.__name__:

附上我的Sublime的Pylinter外掛的User.settings
