Error: EISDIR when using --babelify

[indianscout]

After a fresh installation, the following error occures:

$ node ./node_modules/es6-to-plv8/cmd.js --namespace DetailContentMigration --file ../stateFromHTML/stateFromHTML.js --outfile ../stateFromHTML/stateFromHTML --definitions ~/infektweb/guidelines.v4/dbdata/utils/stateFromHTML/stateFromHTML.json --babelify ../stateFromHTML/babelify.json

I can't actually figure out what exactly is causing this exception but it must be related with babelify.

I've checked all input files and paths an they are all right:

$ ll ../stateFromHTML/stateFromHTML.js
-rw-rw-r-- 1 indianscout indianscout 290 Apr  4 09:29 ../stateFromHTML/stateFromHTML.js
$ ll ~/infektweb/guidelines.v4/dbdata/utils/stateFromHTML/stateFromHTML.json
-rw-rw-r-- 1 indianscout indianscout 142 Apr  4 09:29 
$ ll ../stateFromHTML/babelify.json
-rw-rw-r-- 1 indianscout indianscout 133 Apr  4 11:30 ../stateFromHTML/babelify.json

Absolute paths do not work either:

Opened an issue at browserify: babel/babelify#193

Looks like a babel issue at first glance.

Conclusion: independent of --babelify option a .bablerc has to be present. But unfortunately the --babelify option can not be omitted. Workaround: invoke es6-to-plv8 as follows:

node_modules/es6-to-plv8/cmd.js --namespace MyNs --file example.js --outfile example --definitions /path/to/example.json --babelify .babelrc

Just pass the .babelrc with the --babalify option and everything works as expected.
