Issue with strict mode

Hello,

Currently starting a CI on Codeship using winston. Using babel.

Whenever I try to run my tests i get a

Warning: api/node_modules/winston/lib/winston/common.js: Invalid number (367:30) Use --force to continue.

This might be related to the Octal litteral at 367:30. Fixing this pops another error, also relating to strict mode, about callee, caller and arguments. No line passed to the error stack.

same issue.

+1 really need this to work in strict mode as well.

To reproduce just try creating a winston.js file with the following content:

const winston = require('winston');

and run it using:

node --use-strict winston.js

You get:

/project_home/node_modules/winston/lib/winston/transports.js:23
          return exports[name] = require(fullpath)[name];
                               ^

TypeError: Cannot set property Console of #<Object> which has only a getter
    at Object.acc.(anonymous function).get [as Console] (/project_home/node_modules/winston/lib/winston/transports.js:23:32)
    at new exports.Container (/project_home/node_modules/winston/lib/winston/container.js:24:29)

Quick fix (in case this doesn’t get released soon), add winston to your package json like this and run npm install:

"winston": "winstonjs/winston"

This pulls the master version which works with --use-strict (no issues noticed).
