创建新的 cljs 命名空间时 Lein figwheel 编译错误“pushback buffer overflow”

问题描述

我在 https://github.com/milleva/LyricMaster（发布此内容时为 https://github.com/milleva/LyricMaster/tree/d6d534ff02f098d23c435152627247e753bfb341）有一个开源应用程序的轻量级 figwheel 配置。突然间，对于我来说，没有明显的原因，每当我尝试添加任何新命名空间时，figwheel 都会遇到编译错误 Pushback buffer overflow。

使用 lein figwheel 输出：

figwheel: Cutting some fruit,just a sec ...
figwheel: Validating the configuration found in project.clj
figwheel: Configuration Valid ;)
figwheel: Starting server at http://0.0.0.0:3449
figwheel: Watching build - lyric-frontend
Compiling build :lyric-frontend to "resources/public/js/lyric_frontend.js" from ["src"]...

  Pushback buffer overflow

  1  (ns lyric-frontend.thingy)
                               ^--- Pushback buffer overflow
  2  
  3  (def test "test")

----  Reader Error : Please see src/lyric_frontend/thingy.cljs  ----

这是在几天后重新编写代码后发生的。我已经检查了许多早期的提交，但问题仍然存在。
