In my environment, $LANG=ja_JP.UTF-8 is set by default and the output of aria2c --version is in Japanese.
In that case, the value of the aria2Ver is "aria2 バージョン" instead of "aria2 version", which does not match versionRegex = RegExp(/aria2 version (. *)/) and followiing process throws an error.
To solve this problem, change execSync('aria2c --version') to execSync('LANG=en_US.UTF-8 aria2c --version') so that the output of the command aria2c --version is always in English.
