Why is the running command of the project built by vue wrong?

In the process of learning Vue.js, we often need to use the Vue CLI tool to build projects. However, during project development, we sometimes find that the run commands we enter do not work as we expect. At this time, we need to understand the possible causes and solutions.

1. Possible reasons

1. Version mismatch

When we use different versions of the Vue CLI tool, the command line input may be inconsistent. Right question. Therefore, we want to check to make sure that the versions of our application and dependent packages are compatible with the installed Vue CLI version. You can try the command "vue --version" to view the currently installed Vue CLI version.

2. Conflicting dependencies

When using the Vue CLI tool to build a project, we may install some dependencies, but these dependencies are inconsistent with other existing There is a dependency conflict that prevents the command line from functioning properly. At this time, you can try using the command "npm ls --depth=0" to view all installed dependencies and try to delete or update the problematic dependencies.

3. Missing necessary plugins

Some plugins are required, such as Vue Router and Vuex. If we do not install them or configure them correctly, it may cause the command line to run incorrectly.

4. Configuration Error

We will have some configuration options when creating a Vue project. If the configuration is incorrect, the command line operation will fail. When you can re-create the project, carefully read the configuration options and confirm that the value of each option is correct.

5. Environment configuration issues

Sometimes, incorrect command line input may be related to our local environment configuration. Necessary environment variables may be missing or necessary software packages may be missing. At this time it is best to check whether our environment is configured correctly.

2. Solution

1. Make sure the dependency version matches

Install a Vue CLI version that is compatible with our application and dependencies, and update the existing one dependencies or remove problematic dependencies.

2. Use the correct commands

Make sure you enter the commands correctly and in the correct order. You can refer to the command documentation on the Vue CLI official website.

3. Confirm the correct configuration of plug-ins

Ensure that the required plug-ins are installed correctly and configure these plug-ins correctly as needed.

4. Check configuration options

Check the project configuration options and make sure the value for each option is correct.

5. Check the local environment configuration

Check the local environment configuration and ensure that the required environment variables and packages are installed correctly.

In short, when we use the Vue CLI tool to build a project, we need to carefully check the commands and configuration options, while ensuring that the dependency versions match and the plug-ins are configured correctly. This can effectively avoid problems caused by command line input errors. .
