用jieja做測試學習的時候遇到這么一個報錯

You can now look at the traceback which led to the error. To switch between the interactive traceback and the plaintext one, you can click on the "Traceback" headline. From the text traceback you can also create a paste of it. For code execution mouse-over the frame you want to debug and click on the console icon on the right side. You can execute arbitrary Python code in the stack frames and there are some extra helpers available for introspection: dump() shows all variables in the frame dump(obj) dumps all that's known about the object
遇到報錯不能慌，仔細分析報錯內容：
第一處就是這里：
jinja2.exceptions.TemplateSyntaxError: unexpected char '…' at 208
從上面的報錯隱約感覺似乎和字符相關，但是不能確定具體是哪里的，然后往下看，另外一處報了（主要其他處也看不太明白）：
File "/Users/chenjian/PycharmProjects/testAnaconda/microblog/app/templates/index.html", line 12, in template <!--Jinja2 模板同樣支持控制語句，像在 {%…%} 塊中。讓我們在我們的模板中添加一個
自取檢查index.html 這個文件中發現有中文的注釋，似乎是這里影響了，但是我不熟悉jieba，所以刪掉了這個中文注釋，測試了一下，報錯就消失了。
問題解決了，但是不明白為啥這里的jiaba 不能解析注釋掉的 html的中文代碼。
