Getting 'attempt to index a nil value' on Mac #113

Open vonaurum opened 8 years ago

vonaurum commented 8 years ago

Installed all the required packages on Mac but I get the following error when running the script:

[libprotobuf WARNING google/protobuf/io/coded_stream.cc:537] Reading dangerously large protocol message. If the message turns out to be larger than 1073741824 bytes, parsing will be halted for security reasons. To increase the limit (or to disable these warnings), see CodedInputStream::SetTotalBytesLimit() in google/protobuf/io/coded_stream.h.

Never mind, I just realized that the permissions in the folder were such that only sudo could make changes/run scripts. Changing it fixed the issue.

@vonaurum Could you expand on your issue and how you fixed it? I might be having the same problem you had (I am getting the attempt to index a nil value error).

achag-spec commented 8 years ago

@alexblickenstaff You need to modify the directory permissions to allow reading, writing and execution. I just did that, and it worked.

Thanks, @vonaurum!

I'm having the same problem @AdityaChaganti could you tell me with directory and to change the permissions
