having issues with "dfx start" and "dfx deploy" code - internet-computer

Does anyone know the solution to this? I am new to this and learning. I am on Macbook Air m1.
This is the end code while running dfx start in the terminal:
thread 'replica-actor' panicked at 'called Result::unwrap() on an Err value: Cannot start the replica: Timeout', src/dfx/src/actors/replica.rs:279:78
note: run with RUST_BACKTRACE=1 environment variable to display a backtrace
This is what happens while running dfx deploy in terminal:
Error: An error happened during communication with the replica: error sending request for url (http://127.0.0.1:8000/api/v2/status): error trying to connect: tcp connect error: Connection refused (os error 61)
Does anyone know anything about this?

Found the solution to the problem. I was running the code while it was stored in an external drive. When I created the same folder on my desktop and ran everything the same way, the problem got solved and I no longer have those errors in my terminal. I don't know how it is happening, but I just discovered it right now.

Try "dfx start --emulator"

Undefined method [] for nil when trying to run cap deploy:restart

I have a Rails 5.2 app, and with cap 3.4.1 we are suddenly getting this weird error:
[b35efe76] Phusion Passenger(R) 6.0.8
DEBUG [b35efe76] Finished in 0.305 seconds with exit status 0 (successful).
(Backtrace restricted to imported tasks)
cap aborted!
SSHKit::Runner::ExecuteError: Exception while executing as deploy#host.com: undefined method `[]' for nil:NilClass
Trying to narrow it down, it happens when attempting to restart, because this is the line that fails:
cap production deploy:restart
The question is, how do I go about finding what file is trying to call [] on a nil value on? Running cap with --trace is of no value because it just gives me internal errors - nothing in my code. Basically, how do I find out what is nil?
One more clue, currently, I have a bunch of servers, if I run the cap restart command on server A, it restarts fine, on server B, it throws this error, so I'm guessing there's an environment variable on server A but not B, but the error is just so opaque I don't know where to begin.
Thanks for any help,
kevin
A wild guess: I had a similar problem and I could solve it by upgrading capistrano-passenger to >= 0.2.1
Looks like the version change of passenger from 6.0.7 to 6.0.8 has introduces a problem. I see you are also on 6.0.8, so it might affect you, too!

while start the bro the error is coming "error occurred while trying to send mail: send-mail: SENDMAIL-NOTFOUND not found"

I've installed the Bro IDS but when I try to start the service an error is coming that :
Error: error occurred while trying to send mail: send-mail: SENDMAIL-NOTFOUND not found
starting ...
starting bro ...
bro terminated immediately after starting; check output with "diag"
I've already used broctl install and broctl update but still got the same error.
Kindly help
I've checked the configuration file i.e. node.cfg under /nsm/bro/etc and change the default interface eth0 with my system interface.
now bro has started
Bro can run without sendmail present but you may have been hit by a bug in Bro where it failed to include the Sendmail location in the config files. Whilst it says the bug was supposed to be fixed I've also seen the problem in Bro-2.5. So an easy fix is to do as suggested in the bug report and add the SendMail = /usr/sbin/sendmail to /usr/local/bro/etc/broctl.cfg and then rerun the deployment command:
sudo /usr/local/bro/bin/broctl deploy

MATLAB 2015b (academic version) connector error when starting simulink

Whenever I try to run a simulink(.slx)-file I get this errors in my MATLAB command window:
Error using connector.ensureServiceOn
Error starting MATLAB Connector. Please check that port 31515 is available.
Error in slmsgviewer
Error in slmsgviewer/PersistentInstance
Error in slmsgviewer.processRecord
Error in slsfnagctlr
Error in slsfnagctlr
Error in slsfnagctlr
Error in slsfnagctlr
The simulink file does open but when I try to run, it just says "ready" without doing anything.
The solution that I found from people suffering the same problem was to add a new environment variable:
variable name: "JAVA_TOOL_OPTION"
variable Value: "-Djava.net.preferIPv4Stack=true"
After adding this environment variable and restarting I tried it again but I got the same error.
I also tried "JAVA_TOOL_OPTIONS" and "_JAVA_OPTIONS" with the same value but nothing seems to work.
Is there another way to get rid of these errors?
try to install jdk-7u79-windows-x64, it solved my problem!

OrientDB 2.1.9 crashes with OStorageException EOFException when running SQL script in console

I've been using my SQL database initialization script for a while, but it seems that recently the database crashes in the middle of the execution and I don't know why, but here's some details:
I am running OrientDB on Ubuntu 14 Trusty x64 (via Vagrant)
It always seems to crash while the script attempts to create a UNIQUE_HASH_INDEX, but doesn't always crash at the same UNIQUE_HASH_INDEX instruction
The script creates a lot of vertices and edges, but for example, it will crash here (see line with UNIQUE_HASH_INDEX):
CREATE CLASS Channel EXTENDS V;
CREATE PROPERTY Channel.version LONG;
CREATE PROPERTY Channel.channelId STRING;
CREATE INDEX Channel.uq_channelId ON Channel(channelId) UNIQUE_HASH_INDEX;
The database crashes entirely with the following error:
Creating index... Error:
com.orientechnologies.orient.core.exception.OStorageException: Error
on executing command: sql.create INDEX Channel.uq_channelId ON
Channel(channelId) UNIQUE_HASH_INDEX
Error: java.io.EOFException
Looking at the log files, the only hint I get are the last two lines:
2016-01-14 17:17:05:437 INFO Received signal: SIGTERM [OSignalHandler]
2016-01-14 17:17:05:454 INFO Received signal: SIGTERM [OSignalHandler]
How can I resolve this issue, or at least get better hints as to what is making the database crash?
I also test with OrientDB 2.1.6, as I was running the older version initially. Same problem.
Sorry, false alarm -- this is a Vagrant issue, not an OrientDB issue. Running the exact same script on a 32bit instance instead of 64bit solved my problem, and installing the same script on a real 64bit server also works.

Couldn't register com.xxx.appname with the bootstrap server. Error: unknown error code.Program received signal: “SIGABRT”

I am getting this error while running in device.
Couldn't register com.xxxx.appname with the bootstrap server.
Error: unknown error code.
This generally means that another instance of this process was already running or is hung in the debugger.Program received signal: “SIGABRT”.
Now i rectified this problem .I have posted answer also if anyone got this error follow my post..
Try this,
Deleteing the app, restarting Xcode, clean build, didn't do anything
--> restart your computer
--> restart the phone
