# Troubleshooting

This document covers some common Vue CLI issues and how to resolve them. You should always follow these steps before opening a new issue.

# Running installation with sudo or as root

If you install @vue/cli-service as root user or with sudo, there might be issues when running package postinstall scripts.

This is a security feature of npm. You should always avoid running npm with root privileges because install scripts can be unintentionally malicious.

If you must however, you can workaround this error by setting the --unsafe-perm flag of npm. This can be done by prefixing the command with an environment variable, i.e.

npm_config_unsafe_perm=true vue create my-project

# Symbolic Links in node_modules

If there're dependencies installed by npm link or yarn link, ESLint (and sometimes Babel as well) may not work properly for those symlinked dependencies. It is because webpack resolves symlinks to their real locations by default, thus breaks ESLint / Babel config lookup.

A workaround for this issue is to manually disable symlinks resolution in webpack:

// vue.config.js
module.exports = {
  chainWebpack: (config) => {
    config.resolve.symlinks(false)
  }
}
