article為了減少顯示方程式之間以及文字和方程式之間的空間，我在LyX 的標準文件的 LaTeX 序言中加入了以下命令：
\usepackage[nodisplayskipstretch]{setspace}
\setstretch{1.5}
但我收到以下錯誤訊息，
"LaTeX Error: Option clash for package setspace.
\setstretch
{1.5}
The package setspace has already been loaded with options:
[]
Description: There has now been an attempt to load it with options
[nodisplayskipstretch]
Adding the global options:
,nodisplayskipstretch
to your \documentclass declaration may fix this.
Try typing <return> to proceed."
這是什麼意思，或者我該如何解決它？如何需要減少顯示的方程式和文字之間的空間。
@伯納德。謝謝伯納德。這是供您複製問題的虛擬檔案。 PDF 快照也顯示了該問題。我也會產生一些文本，以防行距有任何問題。

這意味著該setspace包已加載兩次，一次沒有任何選項，一次帶有您的選項。 LaTeX 不喜歡這樣。
您可以按照所說的操作：將選項新增nodisplayskipstretch 至\documentclass 程式碼。
或者，您可以將此行新增至序言：
\PassOptionsToPackage{nodisplayskipstretch}{setspace}
