nvim配置tofu_ls报错：config未找到，请求协助排查

报错信息：config "tofu_ls" not found. Ensure it is listed in config.md or added as a custom server

已完成的操作：

• 安装tofu-ls服务且其已在系统路径中
• 在nvim-lspconfig、mason-lspconfig中完成对应配置
• 确认nvim-lspconfig官方支持tofu_ls

    },
    automatic_enable = true,
  },
}

排查建议 #

1. 验证nvim-lspconfig中的tofu_ls配置是否加载
   在Neovim命令行执行print(require("lspconfig.configs").tofu_ls)，如果输出nil，说明该配置未被正确注册。可以尝试在lspconfig的config函数开头手动加载：

   require("lspconfig.configs").tofu_ls = require("lspconfig.server_configurations.tofu_ls")
   

   重启Neovim后再测试。

2. 检查nvim-lspconfig版本
   当前指定了branch = "master"，可能存在分支代码未同步的情况。可以切换到最新稳定tag版本，或者执行:LspLog查看是否有版本相关的加载错误。

3. 确认Mason与lspconfig的包名映射
   打开:Mason界面搜索tofu相关包，确认安装的包名是否与tofu_ls对应，部分LSP在Mason中的包名可能和lspconfig配置名存在差异。

4. 验证tofu-ls可执行性
   在Neovim中执行:!tofu-ls --version，确认能正常输出版本信息，排除环境变量问题导致Neovim找不到可执行文件的情况。

5. 检查文件类型关联
   打开OpenTofu文件后执行:set filetype?，确认文件类型为opentofu或opentofu-vars。如果不是，可手动添加关联：

   vim.filetype.add({
     extension = {
       tf = "opentofu",
       tfvars = "opentofu-vars",
     },
   })
