I'm setting up a new Vue project and when I'm running the command npm run serve into CMD, the following error appears:

Error: Cannot find module 'C:\Users\Bram Wicherink\@vue\cli-service\bin\vue-cli-service.js'

What do I have to do?

I have read the logs, I uninstalled and reinstalled NPM, Vue, Node.js and read some background information on Google, but nothing worked.

    Run npm install before running npm run serve Commented Sep 13, 2019 at 14:21
  • Then I get the same error, after running npm install before that command. Commented Sep 13, 2019 at 14:35

    It works again! I had to install npm via cmd ('npm install') two times again and strangely it did work? Thanks! Commented Sep 17, 2019 at 6:51

In my case (Windows), the node_modules\.bin\vue-cli-service.cmd was failing because one of my parent folders had an ampersand character which breaks %~dp0

@marts This was a long time ago but from memory yes - that's the simplest fix.

Solution

Removing & from any of the folder's name or sub-folders inside which your project lies will resolve the issue.

Explanation

The & symbol in any of the folders or ancestor/parent folder's name inside which your project lies will initiate a vue-cli execution issue since & is a special character.

The %~dp0 (that’s a zero) variable when referenced within a Windows batch file will expand to the drive letter and path of that batch file.

The variables %0-%9 refer to the command line parameters of the batch file. %1-%9 refer to command-line arguments after the batch file name. %0 refers to the batch file itself.

If you follow the percent character (%) with a tilde character (~), you can insert a modifier(s) before the parameter number to alter the way the variable is expanded. The d modifier expands to the drive letter and the p modifier expands to the path of the parameter.

Example: Let’s say you have a directory on C: called bat_files, and in that directory is a file called example.bat. In this case, %~dp0 (combining the d and p modifiers) will expand to C:\bat_files\.

I had a clean_bins.cmd script run in my project which searches for all /bin/ folders and removes it. After I run that script I had the same problem with vue.

To solve the issue just clean the /node_modules/ folder and run npm install.

Looks like my clean_bins.cmd batch accidentally removed some /bin/ folder in /node_modules/.

This is just from my experience concerning this issue using multiple disks on a windows 10 development environment: I have a work machine using multiple hard-drives: one split for the OS and another for file storage. The vue-cli install by following(droning off) the docs by default installed to my primary disk (C:), however attempting to configure -of which was successful- but running from the secondary disk (D:) resulted in the same error. Running vue-cli commands to create and serve the vue js app (the crux of the issue here) on the primary disk (C:) resolved this issue for me.

Please note: this is not an intact solution but rather observation from my end, even if it may sound trivial.

This worked for me as well. Kind of annoying.

I had an ampersand character in my parent folder, I took 2 hours to try almost everything... Just delete the "&" and then worked.
