Please help me solve this problem

[luo3house]

I guess there is an exception during publish, which caused an es import in cjs module. When I rebuild library, it outputs correctly.

[UnkAtreus]

Issue is still have. Pls help

[allanlisboa]

Did u visit /about page? Error occurs there

[UsVfxArtia]

very sad, seems like it wont be fixed.

[UnkAtreus]

Yeah it wont be fixed but I installed sub component instead of @ant-design/pro-components

[Armito]

same problem

SyntaxError: Cannot use import statement outside a module 心累。。。引入 antd的 table就没问题🤔

[raptoria]

also having this issue...

[alexneo2003]

have same issue
my Content component contain PageHeader component imported from @ant-design/pro-layout
after changing root component import to next/dynamic issue was gone

- import Content from 'components/pages/Course/Content'
+ import dynamic from 'next/dynamic'
import { useRouter } from 'next/router'

+ const Content = dynamic(async () => await import('components/pages/Course/Content'), {
+  ssr: false,
+ })

function ContentPage() {
  return <Content />
}

export default ContentPage

what interesting - in my project i have 5 places where PageHeader was imported but only in one it throws error

[piperubio]

From my part, I was able to solve this thanks to the response from @ogienma at #4852 (comment) in Next.js v13 with Ant Design v5.

[jkiss]

maybe antd-pro is for internal, recommend to make your own pro by using antd. 😃

[ltienphat1307]

I have the same one

[Eureka-Sacha]

same to me .

The error message "SyntaxError: Cannot use import statement outside a module" typically occurs in a Next.js 13 project when you're trying to use an import statement in a file that is not recognized as a module. In Next.js 13, you need to use the .js extension for JavaScript files to be treated as modules.

To resolve this issue, you can try the following steps:

1. Make sure your file has the .js extension. For example, if your file is named example.js, rename it to example.js.

2. Ensure that the file is located in a directory recognized as a module. In Next.js, modules should be placed in the pages directory or any subdirectory inside the pages directory.

3. If you're trying to import a module from a different file, make sure the imported file also has the .js extension and is located in a module recognized directory.

By following these steps, you should be able to resolve the "SyntaxError: Cannot use import statement outside a module" issue in Next.js 13.

const nextConfig = {
  reactStrictMode: true,
  // es 模块编译
  transpilePackages: ['kitchen-flow-editor', '@ant-design/pro-editor', 'zustand', 'leva'],

you can use transpilePackages

[daoyuly]

When you encounter "SyntaxError: Unexpected token 'export'", "'SyntaxError: Cannot use import statement outside a module'" and other related issues, you need to add the module that exposes the issue to the transpilePackages configuration.

const nextConfig = {
  reactStrictMode: true,
  transpilePackages: [
    'rc-util',
    '@ant-design',
    'kitchen-flow-editor',
    '@ant-design/pro-editor',
    'zustand', 'leva', 'antd',
    'rc-pagination',
    'rc-picker'
  ],
}

This helped me to identify and solve a similar problem that was happening to me. Note that the problem is only happening in the Jest environment in my case, in the dev mode and build script it is working correctly without the configuration below:

The weirdest part was that I needed to put the "@babel/runtime" into the transpilePackages list.

/** @type {import('next').NextConfig} */
const nextConfig = {
  transpilePackages: [
    "antd",
    "rc-util",
    "@babel/runtime",
    "@ant-design/icons",
    "@ant-design/icons-svg",
    "rc-pagination",
    "rc-picker",
    "rc-tree",
    "rc-table",
  ],
};

module.exports = nextConfig;

The error that the code above solves is represented by the image below:

For some reason the issue remains for me, babel complaining on build, despite adding it to transpilePackages

Help me plss !!

[NullBetaGG]

The same error was happening to me, my import was like this:

import { Popconfirm } from "antd";

so I changed it to:

import { Popconfirm } from "antd/lib";

and incredibly the webpack error was resolved.

why?

[NullBetaGG]

When you import a module using "antd", webpack looks for the module in the "node_modules" directory and then resolves it based on the main entry point specified in the "package.json" file of the "antd" package. This main entry point could be a JavaScript file or a directory.

In contrast, when you import a module using "antd/lib", webpack directly targets the specific file or directory within the "antd" package without relying on the main entry point specified in "package.json". This can sometimes resolve issues related to how webpack resolves module paths or handles specific files.
