Vim 更新插件时出现错误

Question

现在我在 Mac Osx 中更新我的 .vimrc 但出现以下错误：

处理 /Users/dmuino/.vimrc 时检测到错误：第 59 行：E319：抱歉，该命令在此版本中不可用：py << EOF 第
60 行：E492：不是编辑器命令：导入 os 第 61 行：E492：不是编辑器命令： import sys line 62: E15: Invalid expression: 'VIRTUAL_ENV' in os.environ: line 117: E171: Missing :endif

但我检查了我的 .vimrc 但没有发现任何错误，你能帮我吗？我的 .vimrc 是下一个：
