                                    Sign Up


export default Login;

  1. npm start

I tried with the slim navigation and its works fine if i do not add the

<MDBBtn onClick={() => {settoggle(!toggle)}}>
    <MDBIcon size="lg" icon="bars" />

When adding the code it crashes like the login page

Hi, I downloaded Admin Dashboard Free version and it didn't work at first then i realised that the react and react-dom versions supported by MDBReact are different in packages.json and package-lock.json files. After I changed versions in package.json file with what MDBReact needs in package-lock.json and ran "npm install --package-lock" it worked. Now I am dealing with mdbdatatable but it's different story of course. Here is my package.json

enter image description here

Supratik Chaudhuri free commented 3 years ago

I did the same but it did not solve the issue for me. mdbreact: 5.0.2react, react-dom : 16.12.0 as mentioned in the documentation. Does anyone have any other solution? BTW I'm not using typescript.

josuew pro answered 3 years ago

Hi to all MDB readers i have the solution for this problem :) these are the steps:

node.js version used 14.16.1 LTS react 17.0.2

1.- Download the MDBootstrap Pro version from your orders, i downloaded the npm folder "MDB-React-Super-Bundle".

2.- Extract the file

3.- Open your favorite Text Editor (i was using VS Code)

4.- In VS Code open the zip extracted folder (In VS Code go to file>Open Folder)

5.- Inside the VS Code go to package.json and replace all the code with this code (change the name with your app name):

{ "name": "inventoryapp-react", <- Change this for your app name "version": "0.1.0", "private": true, "dependencies": { "@testing-library/jest-dom": "^5.11.4", "@testing-library/react": "^11.1.0", "@testing-library/user-event": "^12.1.10", "mdbreact": "./mdbreact-5.0.0.tgz", "react-scripts": "4.0.3", "web-vitals": "^1.0.1" }, "scripts": { "start": "react-scripts start", "build": "react-scripts build", "test": "react-scripts test", "eject": "react-scripts eject" }, "eslintConfig": { "extends": [ "react-app", "react-app/jest" ] }, "browserslist": { "production": [ ">0.2%", "not dead", "not op_mini all" ], "development": [ "last 1 chrome version", "last 1 firefox version", "last 1 safari version" ] } }

6.- Extract the mdbreact-5.0.0.tgz file inside the root folder project

This is an example of my project structure:

mdbreact-5.0.0 <- This is the .tgz extracted file node_modules public src License.pdf mdbreact-5.0.0.tgz package.json README.txt yarn.lock

7.- run the next command in the console:

npm install --legacy-peer-deps

8.- Run the application:

npm start

I hope this is useful for all! :) Happy Coding.

josuew pro commented 3 years ago

If you want to keep the original package.json settings just remove the react and react-dom dependencies like this (Replace the next code in you package.json file - Remember to change the app name :D ):

{ "name": "your-app", "version": "0.1.0", "private": true, "// If You want to install mdbreact from our GitLab repository, please replace '5.0.0' with gitURL provided here ->": "git+", "dependencies": { "mdbreact": "./mdbreact-5.0.0.tgz", "react-router-dom": "^5.1.2", "react-scripts": "4.0.1" }, "scripts": { "start": "react-scripts start", "build": "react-scripts build", "test": "react-scripts test --env=jsdom", "eject": "react-scripts eject", "rename": "renamer --find App-clear.js --replace App.js ./src/App-clear.js && renamer --find style.css --replace index.css ./src/style.css ", "remove-demo": "rimraf ./src/assets ./src/components ./src/pages ./src/Routes.js ./src/App.js ./src/index.css && npm run rename" }, "devDependencies": { "renamer": "^1.0.0", "rimraf": "^2.6.2" }, "browserslist": [ ">0.2%", "not dead", "not ie <= 11", "not op_mini all" ] }

I think this solution can help a lot of people :)

Keep coding!

vickrant shinde free answered 3 years ago

getting the same error even with the demo app provided by mdbreact

Krzysztof Wilk staff commented 3 years ago


Try to run the npm dedupe command in your app directory.

Keep coding!

Danni Liu free commented 3 years ago

I tried **npm ls react** and found the react version under mdbreact@5.0.2 is react@17.0.1, and my react version is 17.0.2. I just downgraded to 17.0.1 and did **npm dedupe** and that worked for me.

Krzysztof Wilk staff commented 3 years ago


I think that could be caused by a new version of React (17.0.2). Inside the package, we have 17.01, so It can double the dependency. We'll try to fix it in the next release, but for now, I think it is a good solution :)

Best regards

  • This works for me.
  • Upgrade to react v17
  • uninstall mdbootstrap and mdbreact
  • install mdbootstrap and mdbreact
  • working fine

Piotr Glejzer staff answered 3 years ago

Are you guys using a template with create-react-app? Try to remove <React.StrictMode/> from index.js. I recommend using the version react below 17 to use mdbreact because we didn't update these packages yet.

chadJohn free answered 3 years ago

I am getting the same issue.

I am NOT using typescript

I am on react 16.13.1

And it only happens when I try to use MDBBtn

chadJohn free commented 3 years ago

I am also on the free version.

chadJohn free commented 3 years ago

So I did have duplicate reacts. However, I fixed that issue ( I believe anyways ) since when I now type npm ls react it only shows one now.

chadJohn free commented 3 years ago

So I ended up uninstalling react. Uninstalling mdbreact and then reinstalling mdbreact and it worked. I don't know if this will fix everyones issues but it worked.

I was at the point that I npx a new react app and was about to just redo my app.

Getting same error what should I do???

Piotr Glejzer staff commented 3 years ago

the same question, are you using typescript or not?

MaximeGheraille free answered 3 years ago

when using this packages.json it works for some reason.

enter image description here

and with this one it does not enter image description here

@Ozcan Arslan use the first one and it might also work for you

Piotr Glejzer staff commented 3 years ago

This is not working because you are using 17 version of React. We didn't update package with the latest version about that.

Ozcan Arslan pro commented 3 years ago

I used with 16.12.0 and 16.14.0 versions too still gives error but I am trying to add MDBNavBar.

Piotr Glejzer staff commented 3 years ago

are you using typescript or not?

MaximeGheraille free commented 3 years ago

@Ozcan Arslan did you try with 16.3 like me, its works with that one

Ozcan Arslan pro answered 3 years ago

I am getting exactly the same error using MDBNavbar in mdbreact free v4.27.0. It's working fine with reactstrap or react-bootstrap navbar but I need to use MDBNavbar.
