Why do I get a 'TypeError: Cannot read properties of null (reading 'useState')' error when installing my React UI package through an absolute path?

问题

我已经为React编写了一个UI包,并通过Rollup包管理器进行编译。当我将其发布到我的个人Bitbucket存储库并从云中安装它们,例如:npm i https:lik-to-the-repo,包可以正常工作,但当我通过绝对路径进行安装时,例如:npm i / Users/myname/Projects/Work/project-name"

我使用了 external: [/node_modules/] 来告诉Rollup,所有我的包都是外部的,并且应该在运行时导入。

但是,当我使用 npm pack 打包我的包并在我的存储库中链接打包文件,即 'file:../pack-dir/pack-name.tgz' 时,它可以正常工作

我面临以下错误

TypeError: Cannot read properties of null (reading 'useState')
    at Object.useState (http://localhost:5173/node_modules/.vite/deps/chunk-ONATIWGS.js?v=e6bdb091:1066:29)

我指定给npm安装的项目目录是我的package.json文件所在的地方。在 /Work/project-name/package.json 中,它成功地将我的包安装到了 node_modules 中,名称与我的 package.json 中指定的一样。

我在 package.json 中添加了入口路径

"main": "dist/index.cjs",
"module": "dist/index.js",
"files": [
    "dist"
],
"types": "dist/index.d.ts",
"peerDependencies": {
    "react": "^18.0.0",
    "react-dom": ">=16.6.0"
},

我的Rollup配置如下:

export default [
  {
    input: 'src/index.ts',
    output: [
      {
        dir: 'dist',
        format: 'cjs',
        entryFileNames: '[name].cjs',
        exports: 'auto',
        // ...outputOptions,
      },
      {
        dir: 'dist',
        format: 'esm',
        // ...outputOptions,
      },
    ],
    external: [/node_modules/],
    plugins: [
      peerDepsExternal({ includeDependencies: true }),
      resolve(),
      commonjs(),
      // ...其他插件
    ],
  },
  // 其他配置...
];

我尝试使用 npm link,但仍然遇到相同的问题。我正在使用React与Vite和SWC模块。

英文:

I have written a ui package for react and I am compiling them through rollup package manager. When I publish to my personal bitbucket repo and install them from the cloud eg: npm i https:lik-to-the-repo the package works fine but when I am doing an install it through the absolute path eg; `npm i / Users/myname/Projects/Work/project-name".

I am using external: [/node_modules/] to let rollup know that all all my packages are external and should imported on the run-time.

But it works fine when i pack my package using npm pack and link the packed file in my repo ie. 'file:../pack-dir/pack-name.tgz'

I am facing this error


TypeError: Cannot read properties of null (reading 'useState')
    at Object.useState (http://localhost:5173/node_modules/.vite/deps/chunk-ONATIWGS.js?v=e6bdb091:1066:29)

The project directory I specify for npm to install is where my package.json file exists. Inside /Work/project-name/package.json, It successfully installs my package in node_modules with the name specified in my package.json

Added the entry path in package.json

    "main": "dist/index.cjs",
    "module": "dist/index.js",
    "files": [
        "dist"
    ],
    "types": "dist/index.d.ts",
    "peerDependencies": {
        "react": "^18.0.0",
        "react-dom": ">=16.6.0"
    },

my roll-up config

          '**/*.stories.tsx',
        ],
      }),
      //   typescriptPaths(),
    ],
  },
  {
    input: 'src/assets/scss/imports.scss',
    output: [
      {
        file: 'dist/lib-ui.css',
      },
    ],
    plugins: [
      postcss({
        plugins: [postcssImport()],
        extract: path.resolve('dist/lib-ui.css'),
        minimize: true,
        modules: false,
      }),
    ],
  },
  {
    input: 'dist/index.d.ts',
    output: [{ file: 'dist/index.d.ts', format: 'esm' }],
    plugins: [dts()],
    external: [/\.css$/, /\.scss$/],
  },
];

I tried using npm link then too I face the same issue. I am using react with vite and swc modules.

得分: 1

从错误信息中,我可以看到React/JSX语法存在问题。

这让我产生了一些疑问:

  • 您的项目 "project-name" 中是否正确安装了所有React依赖项?
  • 您是否需要使用React插件?
import react from '@rollup/plugin-react'

plugins:[
  react(),
],
英文:

from the error i can see something is wrong with react/JSX syntax

this makes me come a couple of doubts:

  • every react dependency is correctly installed in your project "project-name"?

  • don't you have to use the react() plugin too?

     import react from '@rollup/plugin-react'
    
     plugins:[
       react(),
     ],
