重新混合源映射支持 `TypeError: 列必须大于或等于 0，得到 -1`

Question

使用bun和express运行remix，我遇到了

source-map-support

错误。

用类似express的代码

sourceMapSupport.install({
  retrieveSourceMap: function (source) {
    console.log(source, `${source}.map`)
    return {
      url: source,
      map: fs.readFileSync(`${source}.map`, "utf8"),
    }
  },
})

要恢复源映射，我收到错误：

/Users/dangoodman/code/sellmyai/build/index.js /Users/dangoodman/code/sellmyai/build/index.js.map
583 |     if (aNeedle[aLineName] <= 0) {
584 |       throw new TypeError('Line must be greater than or equal to 1, got '
585 |                           + aNeedle[aLineName]);
586 |     }
587 |     if (aNeedle[aColumnName] < 0) {
588 |       throw new TypeError('Column must be greater than or equal to 0, got '
                  ^

      at processTicksAndRejections (:61:77)

（省略

retrieveSourceMap

选项会导致相同的错误）

我可以确认该文件存在于该位置。我的

remix.config.js

看起来像：

/** @type {import('@remix-run/dev').AppConfig} */
export default {
  ignoredRouteFiles: ["**/.*"],
  serverModuleFormat: "esm",
  appDirectory: "src/remix",
};

我将混音放入面包中，例如：

import * as build from "../build/index.js"

app.all("*", createRequestHandler({ build: build as any }))

并拥有开发命令：

"remix dev --manual -c \"bun --watch run src/index.ts\""

如果我登录我得到的来源（基于下面的评论）：

从最新的 Express 模板中尝试一下：

sourceMapSupport.install({
  retrieveSourceMap: function (source) {
    const match = source.startsWith("file://");
    if (match) {
      const filePath = url.fileURLToPath(source);
      const sourceMapPath = `${filePath}.map`;
      if (fs.existsSync(sourceMapPath)) {
        return {
          url: source,
          map: fs.readFileSync(sourceMapPath, "utf8"),
        };
      }
    }
    return null;
  },
});
