使用Rollup执行命令时遇TypeError路径参数类型错误求助

问题场景 #

执行命令rollup -c --config rollup.config.js时，触发如下TypeError错误：

[!] TypeError: The "path" argument must be of type string. Received an instance of Array

原Rollup配置文件 #

const dts = require("rollup-plugin-dts");
const esbuild = require("rollup-plugin-esbuild");
const name = require("./package.json").main.replace(/\.js$/, "");

const bundle = (config) => {
  return {
    ...config,
    input: "src/index.ts",
    external: (id) => !/^[./]/.test(id),
  };
};

export default [
  bundle({
    plugins: [esbuild()],
    output: [
      {
        file: `${name}.js`,
        format: "es",
      },
      {
        file: `${name}.mjs`,
        format: "cjs",
      },
    ],
  }),
  bundle({
    plugins: [dts()],
    output: {
      file: `${name}.d.ts`,
      format: "es",
    },
  }),
];

依赖版本信息 #

{
  ...
  "rollup": "^3.21.5",
  "rollup-plugin-dts": "^5.3.0",
  "rollup-plugin-esbuild": "^5.0.0",
  ...
}

已尝试的无效修改 #

使用path模块规范化路径后，问题仍未解决，修改后的配置如下：

const path = require("path");
const dts = require("rollup-plugin-dts");
const esbuild = require("rollup-plugin-esbuild");
const name = require("./package.json").main.replace(/\.js$/, "");

const bundle = (config) => {
  return {
    ...config,
    input: path.resolve(__dirname, "src/index.ts"),
    external: (id) => !/^[./]/.test(id),
  };
};

export default [
  bundle({
    plugins: [esbuild()],
    output: [
      {
        file: path.resolve(__dirname, `${name}.js`),
        format: "es",
      },
      {
        file: path.resolve(__dirname, `${name}.mjs`),
        format: "cjs",
      },
    ],
  }),
  bundle({
    plugins: [dts()],
    output: {
      file: path.resolve(__dirname, `${name}.d.ts`),
      format: "es",
    },
  }),
];

最终解决方法 #

错误的核心原因是命令行参数重复：-c是--config的简写形式，同时传递两个参数会导致Rollup的参数解析逻辑混乱，误将配置文件路径识别为数组类型，从而抛出TypeError。

只需使用以下任一命令执行即可：

• rollup -c rollup.config.js
• rollup --config rollup.config.js
