在emacs 23中使用软件包安装安装python模式时出错

我在scientific linux上运行emacs 23。我试图让python模式工作，但当我试图通过package install[RET]-python模式安装它时，我会收到一长串警告，首先是：

Leaving directory `/home/umroot/.emacs.d/elpa/python-mode-20150909.2301'

以

我不知道还有什么可能与此相关。我正在使用Anaconda for python。

python-mode.el在每次提交/上传之前都要经过测试。到目前为止还没有已知的关键bug

尽管如此，我们仍将研究如何减少警告。万一

python mode.el:2315:7:警告：将变量赋值给常量

`py-block-closing-keywords-re'

例如，使用defvar而不是defconst应该可以让它消失

谢谢报道
