Oh... I see, you have different versions. Wait for resolving #136

Yes, I have downgraded mdbook to version 0.4.52 and the issue has been resolved. However, I have encountered other problems. {{ #playground }}, {{ #include }}, and {{ #rustdoc_include }} cannot be processed correctly. I hope this can be optimized. For reference, see https://github.com/monstertsl/rust-lang-book.

{{ #playground }}, {{ #include }}, and {{ #rustdoc_include }} cannot be processed correctly

All those tags are processed by mdbook so better to check it first. That is something odd every time. so I did 'custom' mdbook version earlier.

A incorrect version issue is fixed by #141

The {{ #playground }}, {{ #include }}, and {{ #rustdoc_include }} cannot be processed correctly

That needs separate issue, because generated html looks odd.
