Hi, I'm a beginner in programming and when running npm start I got this error: Error: Cannot find module express-session plus two other errors. I'm using Node 18 on Windows 10 and I uploaded the project files to https://www.dropbox.com/scl/fi/7q2wu8vu7mcdm96oi59hc/ClothesTiffaandCo.zip?rlkey=8gyurd6my7dnocmorlumm67tr&st=yaughbuw&dl=0
Here is a practical guide to solve the problem step by step. 1 Run npm install express-session in the project folder to install the missing package. 2 Check the package.json file and make sure express-session is in dependencies. 3 If the installation seems to fail, delete the node_modules folder and the package-lock.json file and run npm install again. 4 Clean the npm cache with npm cache clean --force if you suspect corrupted packages. 5 Check if your project uses CommonJS or ES Modules by looking at the type property in package.json; if you use ES Modules adapt the imports with import, otherwise use require. 6 Verify how you import or require express-session and the middleware configuration in express to initialize sessions correctly. 7 On Windows try running the terminal with administrator privileges if there are permission issues.
Regarding the other two errors that appear alongside the express-session issue, check the full messages in the console to identify missing file paths, syntax errors, or missing dependencies. Run node mainFile.js directly to see the full trace. Check relative paths, uppercase and lowercase in file names, and that all necessary modules are listed in package.json. If you use dynamic imports or aliases, check the bundler or Node configuration.
Node 18 on Windows 10 is generally not the cause of this specific error, except in cases of version incompatibilities with very old packages. If you still have problems after following the steps, consider trying a different LTS version using nvm or nvm for Windows to rule out incompatibilities.
