Viper: WriteConfig fails to write if file does not exist

[lllama]

The new WriteConfig function ends up calling findConfigFile, which in turn checks whether the file exists. If it doesn't then it returns an error, which stops the config being written.

I had similar issue too and filed as #430 and right now my workaround is like this,

if err := viper.SafeWriteConfigAs(configPath); err != nil {
    if os.IsNotExist(err) {
        err = viper.WriteConfigAs(configPath)
    }
}

I'm just hoping there is a better solution.

Use WriteConfigAs which creates the file before writing.

I got same issue.
I think WriteConfig should create configfile as same as WriteConfigAs if the file does not exist
