Trying to install OpenFL - haxelib returns invalid operation

Question

I'm trying to install OpenFL in a windows system. I have already installed haxe but when I run haxelib install openfl in command prompt, haxelib returns Invalid operation(+). Any ideas about how can this problem be solved?

Answer 1

The error message is most likely related to haxelib/neko trying to add two null strings.

I have encountered an issue before with Jenkins, since Jenkins removes HOMEDRIVE and HOMEPATH from the env-vars while doing a build. You may be encountering something similar.

Check and make sure HOMEDRIVE and HOMEPATH are set in your current shell, the re-try haxelib. If this does not work, we'll have to narrow down further.
