Failed to remove erlang builds using kerl

Question

I installed Erlang using kerl. I built it as 32-bit, not 64-bit, as it should. Trying to fix my mistake was problematic.

./kerl status 

brings me

 Available builds: R15B01,r15b01 ---------- Available installations: ---------- The current active installation is: /Users/jason/erlang/r15b01 

Then when i try

 ./kerl delete r15b01 

or

 ./kerl delete r15b01 

I get

 No build named r15b01 

and

 ./kerl build R15B01 r15b01 

gives me

 There already a build named r15b01 

Therefore, I cannot rebuild, and I cannot delete the old one. I know that, most likely, I missed something very obvious, but I am new to this and can not find anything on it.

thanks!

Answer 1

You are misinterpreting the syntax for deletion. You need to specify the type of deletion you are doing before specifying the actual assembly.

Instead...

kerl delete build_name

You must enter ...

kerl delete build line_name
kerl delete installation path

To get a list of already installed assemblies or installation paths that you can remove:

kerl list builds
kerl list settings

Answer 2

To view registered settings:

 kerl list installations 

To remove one of them:

 kerl delete installation /full/path/from/above 

Use the absolute path here, as shown in the list command.

If the uninstall command failed, you can also remove the installation line in the file `~ / kerl / otp_installations, which is not an official solution. Remember to also delete the remaining installation files manually.
