Unable to open cypress UI

[thecodejack]

Current behavior:

We are having a VM machine which multiple users connect. Multiple users also use cypress. Now problem is when I run cypress open. Cypress is trying to access/create folder named /tmp/cypress and place a lock file there. But if another user runs same command after folder is created, it throws following error

[OperationalError: EACCES: permission denied, open '/tmp/cypress/4fa88ed0720f436f49e09ac33f63413a.lock'

] {  cause: [Error: EACCES: permission denied, open '/tmp/cypress/4fa88ed0720f436f49e09ac33f63413a.lock'    ] {
    errno: -13,
    code: 'EACCES',
    syscall: 'open',
    path: '/tmp/cypress/4fa88ed0720f436f49e09ac33f63413a.lock'
  },
  isOperational: true,
  errno: -13,
  code: 'EACCES',
  syscall: 'open',
  path: '/tmp/cypress/4fa88ed0720f436f49e09ac33f63413a.lock'
}
Error: EACCES: permission denied, open '/tmp/cypress/4fa88ed0720f436f49e09ac33f63413a.lock'

Desired behavior:

A way where this error doesn't occur. Possible solutions that come to my mind are

• config
• automatically try creating another folder proably /tmp/cypress01
• create cypress folder with access to all groups and users of the machine.

Cypress requires root access, you'll need to install it accordingly and make sure you have the proper permissions set. See #1281

@jennifer-shehane So maybe we need to add check if we have root access and throw better error message?

@jennifer-shehane

this seems to be bit different to what discussion is happening in #1281 . Probably root access will helps but if cypress can create folder and set permissions right in /tmp/cypress, this can be resolved easily.

I think you should add also root access issue to trade-offs if can't be fixed. This is kind of a blocker that can make developers/companies rethink about cypress before committing.

Some of this will be addressed in #7126
