问题描述
在 Visual Studio Code 的 LaTeX 配置中使用 LTeX 扩展时，打开包含 LaTeX 文档的文件夹会出现如下错误提示：
报错信息提示：
Could not run ltex-ls with Java, please see the output panel ‘LTeX Language Client’ for details. You might want to try offline installation.
紧接着出现：
以下是 LTeX 语言客户端的输出信息：

系统中通过 Chocolatey 和 winget 安装了多个 Java 版本。运行命令 where java 得到如下结果：
C:\Program Files\Eclipse Adoptium\jre-8.0.422.5-hotspot\bin\java.exe
C:\Program Files (x86)\Common Files\Oracle\Java\java8path\java.exe
C:\Program Files (x86)\Common Files\Oracle\Java\javapath\java.exe
C:\Program Files\AdoptOpenJDK\jdk-15.0.2.7-hotspot\bin\java.exe
C:\ProgramData\Oracle\Java\javapath\java.exe
C:\Program Files\Microsoft\jdk-11.0.16.101-hotspot\bin\java.exe
C:\Program Files\OpenJDK\jdk-22.0.2\bin\java.exe
这是我的 LaTeX 配置文件 settings.json：
{
"editor.formatOnSave": true,
"ltex.java.path": "C:\\Program Files\\Microsoft\\jdk-11.0.16.101-hotspot\\bin\\java.exe"
}
解决方案
我参考了 tobiscode 在这篇帖子中提供的方案，成功解决了该问题：
https://github.com/valentjn/vscode-ltex/issues/884#issuecomment-2263630384
需对 extensions.js 文件进行修改，该文件位于：
%USERPROFILE%\.vscode\extensions\valentjn.vscode-ltex-13.1.0\dist
具体修改如下：
- 将第13516行的：
const executableOptions = {
encoding: 'utf-8',
timeout: 15000,
};
修改为：
const executableOptions = {
encoding: 'utf-8',
timeout: 15000,
shell: true,
};
- 将第13616行的：
const executableOptions = {
encoding: 'utf-8',
timeout: 15000,
};
修改为：
const executableOptions = {
encoding: 'utf-8',
timeout: 15000,
shell: true,
};
- 将第24689行的：
const execOptions = Object.create(null);
改为：
const execOptions = {
shell: true
}
- 将第24823行的：
options.cwd = options.cwd || serverWorkingDir;
改为：
options.cwd = options.cwd || serverWorkingDir;
options.shell = true;
以上修改启用了 shell: true 选项，解决了 LTeX 扩展无法通过 Java 运行的问题。
