\begin{itemize}
\item [1)]
\begin{eqnarray}
~~&&x_i\in R_{+} =\{x \mid \|\phi(x_{i})-C_{+}^{*}\|^{2} \textless R_{+}^*\}\nonumber\\
\Rightarrow \alpha_{i}=0;
~~&&\end{eqnarray}
\item [2)]
\begin{eqnarray}
~~&&x_i\in M_{+} =\{x \mid \|\phi(x_{i})-C_{+}^{*}\|^{2} = R_{+}^*\}\nonumber\\
~~&&\Rightarrow \alpha_{i}\in \[0,\frac{c_1}{l^{+}}\];
\end{eqnarray}
\item [3)]
\begin{eqnarray}
~~&&x_i\in L_{+} =\{x \mid \|\phi(x_{i})-C_{+}^{*}\|^{2}\textgreater R_{+}^*\}\nonumber\\
~~&&\Rightarrow \alpha_{i}=\frac{c_1}{l^{+}};
\end{eqnarray}

错误提示为
Lonely \item--perhaps a missing list environment. \item [3)]
请教各位,\item[3)]不是在 \begin{itemize}的环境中吗...为啥还会出现这个qwq
