  Does your workplace require a proxy to be used to access the Internet? If so, you must configure the HTTP_PROXY environment variable before downloading Cypress. Read more: https://on.cypress.io/proxy-configuration

  Otherwise, please check network connectivity and try again:`

const binaryNotExecutable = executable => {

    Reasons this may happen:

    - node was installed as 'root' or with 'sudo'
    - the cypress npm package as 'root' or with 'sudo'

    Please check that you have the appropriate user permissions.

    You can also try clearing the cache with 'cypress cache clear' and reinstalling.
  `
  };
};
const notInstalledCI = executable => {
  return {
    description: 'The cypress npm package is installed, but the Cypress binary is missing.',
    solution: stripIndent`\n
    We expected the binary to be installed here: ${chalk.cyan(executable)}

    Reasons it may be missing:

    - You're caching 'node_modules' but are not caching this path: ${util.getCacheDir()}
    - You ran 'npm install' at an earlier build step but did not persist: ${util.getCacheDir()}

    Properly caching the binary will fix this error and avoid downloading and unzipping Cypress.

    Alternatively, you can run 'cypress install' to download the binary again.
