Error when updating Heroku CLI: write lock exists:

Question

I am trying to update the Heroku CLI, however, without success.

Current version of Heroku CLI is

heroku-cli/6.15.5-1f03166 (win32-x64) node-v9.3.0

When running

heroku update

I get the following error

C:\>heroku update
CLI is updating... !
 !    'ELOCK': write lock exists: update

I didnt' find any solution to this problem so far as I am hesitating to just uninstall and re-install the Heroku CLI (all my configs are lost then).

Answer 1

Not sure what the cause of this was but restarting solved the issue for me. Good luck!

11:53:26 | ~  : heroku update

Answer 2

I had the same problem and I solved removing this file:

/Users/YOUR_USER/Library/Caches/heroku/update.lock

I use mac, but I guess you will have same file in a similar location

Answer 3

I had the same problem on the Mac - solved it by running htop, filtering by heroku and killing all processes.

TLDR; kill running Heroku processes

Answer 4

I also had the same problem and solved it by removing error.log from the following directory in Windows 10: C:\Users\Behzad.heroku\error.log

Answer 5

I solved this problem by uninstalling heroku and installing via command line: npm install -g heroku So I got the most current version.
