我知道这个一般性问题并不新鲜，但这似乎是我个人的问题。

我尝试在 Windows 7 下为 Python 3.3 安装 pylint（是的，我知道它不受支持，但我知道这是可能的 - 因为我的一位同事做到了，但遗憾的是他对已知问题的解决方法不适用于我的电脑 - 并且他有 Windows 8 ...)

这个时候我已经安装了python 3.3，先尝试通过pip安装pylint，失败了。

搜索和与我的同事的一些谈话带来了这个答案： 没有运气 pip-installing pylint for Python 3

我设法按照这些说明安装了 pylint，但是其中一个依赖项（logilab-astng）失败了。

我检查了 setup.py 脚本并意识到“2to3”转换没有在我的机器上运行（我认为是由于路径问题） - 我重新配置了转换并且它运行了。

之后所有安装过程（pylint、logilab-astng、logilab-common）都退出“成功” - 但如果我启动 pylint，我会收到以下消息：

我期待着你的想法！

问题在于，保存 pylint 使用的 ast 表示的 logilab-astng 尚不支持在 python 3.3 中引入的“yieldfrom”节点。

您可能想尝试下面的补丁，它应该可以解决问题：

diff --git a/rebuilder.py b/rebuilder.py
--- a/rebuilder.py
+++ b/rebuilder.py
@@ -877,10 +877,12 @@ class TreeRebuilder3k(TreeRebuilder):

             newnode.orelse = [self.visit(child, newnode) for child in node.orelse]
         newnode.set_line_info(newnode.last_child())
         return newnode

+    def visit_yieldfrom(self, node, parent):

 if sys.version_info >= (3, 0):
     TreeRebuilder = TreeRebuilder3k
