Sublime的插件都是用Python写的，但是我并不会Python，但日志信息第一行可以看出
OmniMarkupPreviewer: [INFO] Launching web browser for http://127.0.0.1:51004/view/29
这是命令Preview Markup in Browser 开始执行，
下行开始就是错误信息，这里指出了是 UnicodeEncodeError 的错误。 UnicodeEncodeError('latin-1', '夏至', 0, 2, 'ordinal not in range(256)')

3.查找原因

我一开始以为是中文编码的问题，但是整篇文章无论是否有中文字符都是无法显示。但是日志信息中的第一行让我突然想起来我的计算机名字，没错就是下图

计算机名夏至，这样子应该可以对上了，感觉应该是无法发送数据到我本机上。

4.更改计算机名

更改下计算机名，转为英文，按要求重启

5.问题解决

最终结果，可以正常显示了。

结束语

感觉这应该是一个比较容易忽略的地方，虽然大多数人没有设置计算机名为中文的习惯，但是这个地方出了问题感觉还是难以发现的，记录下来和大家分享。
