Foreword:
After using vue create to create the project , the following error is reported through npm run serve ;
Error: @vitejs/plugin-vue requires vue(>=3.2.13) or @vue/compiler-sfc to exist in the dependency tree.
Then follow the error prompts and perform npm install '@vue/compiler-sfc' --save-dev ; do it again after the installation is complete.
npm run serve still reports the above error .
Start looking for differences:
Comparing the normal projects built before, I found the differences: (start to try to solve the problem according to your own ideas)
1. Execute npm uninstall vue to uninstall vue dependency packages in abnormal projects
2. Then execute npm install [email protected] --save-dev to install the vue dependency package into the devDependencies dependency tree.
3. Execute npm run serve again
^_^ Project started successfully! ! !
