Vim錯誤E745在`neosnippet`中創建`Latex`片段時'使用列表作爲數字'

Question

我使用neosnippet爲latex模板創建片段。這段代碼相當長，當我嘗試展開代碼段時，我一直在收到奇怪的錯誤E745 Using a List as a Number。

以下是neovim發佈的錯誤消息。

[dein] Error occurred while executing hook: neosnippet.vim 
[dein] Vim(let):E745: Using a List as a Number 
Error detected while processing function <SNR>346 snippets_expand ... 
Line 11 
E15: invalid expression: 
E15: invalid expression 

實際的代碼片段本身在下面 - 它很長。現在，當我從片段文件中取出這個長片段時，所有其他片段都可以正常工作。所以它似乎在某個地方我正在使用我不應該使用的角色或什麼的。或者可能是某些東西沒有正確逃脫，等等。

我所有的其他膠乳片段都能正常工作，但也有短得多。有沒有人有任何想法，爲什麼這個片段造成這麼多麻煩？

這是乳膠片段。

好的，我與開發人員交談過，他表示問題與本文檔中的反引號有關。

\newcommand{\forwards}{\mbox{````$\Longrightarrow$''}\xspace} 
\newcommand{\backwards}{\mbox{````$\Longleftarrow$''}\xspace} 

我更新了neosnippet插件，也改變了latex代碼。現在事情工作正常。
