我的问题是 Overleaf 无法编译我的文件，也无法生成 PDF。你能帮我解决这个问题吗？这是我的网址https://www.overleaf.com/read/yyffrwsrdbwq 它很长所以我不会复制粘贴它。
答案1
你的代码中有很多错误。这就是你无法编译代码的原因。
为了给您一个起点，请查看我从您给出的代码中浓缩出来的以下代码，以向您展示表格中的错误。请注意，您的公式中也有错误需要纠正，但如果您在纠正表格后无法解决问题，我认为您应该就该问题提出一个新问题...

我用 标记了重要的代码更改<==========。
不要使用\\来开始新段落，而应使用空白行：
Therefore, our first hypothesis states the following:%\\ % <=========== no! never!
%\\ % <================================================================ no! never!
您的第一个 longtable 被定义为使用 4 列，但您只有三列的数据。表格的开头应该有标题，请注意标签必须跟在命令后面\caption。请注意，longtable 命令\caption{...}\label{}\\必须以以下内容结尾\\：
\begin{longtable}{l l l} % <============================================ 3 columns
\caption{Multivariate studies included in the meta-regression analysis}\label{subsec:Intro/table}\\
\toprule
\textbf{Study} & \textbf{Service} & \textbf{Effect}\\
\midrule
Bel \& Costas (2006) & solid waste & saves costs \\
请查看我添加了包booktabs以便能够使用命令\toprule，\midrule和\bottomrule。请查看我在表格中进行的漂亮打印，以获得更易读的表格代码...
在您的第二张表中，您忘记添加$数学内容：
\begin{center}
\begin{tabular}{ c c }
$b_j$ & reported coefficient \\ % <==============================
$\beta$ & true effect \\
$\alpha_k$ & meta-regression coefficients\\
$Z_{jk}$ & meta-independent variables\\ % <==========================
$e_j$ & disturbance term of the meta-regression
\end{tabular}
\end{center}
请注意，您必须使用$Z_{jk}$索引 jk! 来获取 Z，$Z_j_k$这完全是错误的！
在您最后显示的表格中
\begin{longtable}{l|rrrrr}
\toprule
& OLS & Robust OLS & GEE & GLS \\
\midrule
Sample Size & 6.78E-05 & 6.78E-05* & 7.15E-05** & 1.30E-04\\

我猜那\label应该是之前的表格的标签吧？如果是的话，添加一个\caption以下内容\label，就像在第一个表格中所做的那样...
通过此答案中提到的更正，您将获得上面的编译代码，结果如下：
以及表 2 和表 3：
我建议去掉标有红色箭头的垂直规则
\begin{longtable}{l|rrrrr}
到
\begin{longtable}{lrrrrr}
请按照此处所示更正您的原始代码，然后检查公式中的错误。
请参阅，这是为了帮助您入门，有更多可能性来获得更好的表格，但首先，获得编译代码很重要，我猜......
请提出一个新问题，仅显示您有问题的公式的可编译代码......
答案2
尝试通过单击此图像右上角显示的“垃圾”按钮来清除缓存... 就我而言，没有错误。但之前出错的缓存导致问题，并且无法编译。
