如何解决“无法解决‘@/...’中的导入”问题？

Question

这是我得到的错误。我在“vite.config.ts”文件中定义的文件路径有问题。你能帮助我吗？

错误日志

错误信息：

FAIL  tests/utils/ConvertFromDomainToCountryCode.test.ts [ tests/utils/ConvertFromDomainToCountryCode.test.ts ]
Error: Failed to resolve import "@/constant" from "src/assets/ts/_utils/ConvertFromDomainToCountryCode.ts". Does the file exist?

ConvertFromDomainToCountryCode.test.ts文件

import { describe, expect } from "vitest";
import { SetFlags } from "../../src/assets/ts/_utils/ConvertFromDomainToCountryCode.ts";

describe("Convert From Domain To CountryCode", () => {
  test("function defined", () => {
    expect(SetFlags).toBeDefined();
  });
});

当我设置文件路径“../../../constant/index”时，它工作正常。

ConvertFromDomainToCountryCode.ts文件

import { COUNTRY_INFO } from "@/constant";

这里我添加了“别名”

vite.config.ts文件

import { fileURLToPath, URL } from "node:url";

import { defineConfig } from "vite";
import vue from "@vitejs/plugin-vue";
import { resolve, dirname } from "node:path";
import vueJsx from "@vitejs/plugin-vue-jsx";

export default defineConfig({
  plugins: [
    vue(),
    vueJsx()
  ],
  resolve: {
    alias: {
      "@": fileURLToPath(new URL("./src", import.meta.url))
    }
  },
  base: "/"
});

只是等待找到文件的路径

Answer 1

我解决了这个错误。我在文件中添加此代码vitest.config.ts。

resolve: {
  alias: [{ find: "@", replacement: resolve(__dirname, "./src") }]
}

Answer 2

有同样的问题，答案有助于解决它，但我想添加你可以从路径导入解析

import { resolve } from 'path'

如果您尚未声明，@但tsconfig您有某些特定文件夹的动态路径，则可以指定它们。

resolve: {
  alias: [{ 
    find: "@server", 
    replacement: resolve(__dirname, './src/server/') 
  }]
}
