Failed to register observatory port with mDNS with error

An error is reported when Fletter runs IOS real machine: failed to register observation port with mDNS with error

Errors are reported as follows

[VERBOSE-2:FlutterObservatoryPublisher.mm(101)] Failed to register observatory port with mDNS with error -65555.
[VERBOSE-2:FlutterObservatoryPublisher.mm(103)] On iOS 14+, local network broadcast in apps need to be declared in the app's Info.plist. Debug and profile Flutter apps and modules host VM services on the local network to support debugging features such as hot reload and DevTools. To make your Flutter app or module attachable and debuggable, add a '_dartobservatory._tcp' value to the 'NSBonjourServices' key in your Info.plist for the Debug/Profile configurations.

Solution: (refer to the official link document above)

On iOS 14 and higher, enable the Dart multicast DNS service in the Debug version of your app to add debugging functionalities such as hot-reload and DevTools via flutter attach.

1. Rename the application’s info.plist to info-debug.plist. Make a copy called info-release.plist and add it to the Xcode project
2. In info-debug.plist, add the key nsbonjourservices and set the value to_ dartobservatory._ tcp

(optional) add the key nslocalnetworkusagedescription to the text of the desired custom permissions dialog box. (Note: ‘allow shutter tools on your computer to connect and debug your application. This prompt will not appear on release builds.’)

3. In target’s build settings, modify the info.plist file path path/to/info.plist to path/to/Info – $(configuration). Plist.
4. In target’s – & gt; Build Settings > Build Phases > Copy bundle resources build phase. If info-release.plist is deleted (I have deleted it in the figure below)

Error:java.io.FileNotFoundException: Path is not a file [How to Solve]

Hadoop (daily error) counts words. Error: java.io.filenotfoundexception: path is not a file:

My solution:

Generally, the jar package source code is not written well. You can check your source code. The problem I have is that the data path is not set well, so HDFS cannot find the file. Before modification:

after modification: must be the absolute path of the data file in Hadoop!! After modification, I run successfully! Hope to help you!

Error: can’t access JTAG chain problem solving method

Burn the program into the FPGA chip with USB blaster, and the prompt is “error: can’t access JTAG chain”, and then the test JTAG chain still prompts this problem. After looking for the information on the Internet, I summarized the reasons for the prompt of “can’t access JTAG chain” when downloading. The common reasons are as follows:

(1) The selected FPGA model is inconsistent with the hardware;

(2) The communication between the parallel port and the download line is faulty or the download line is broken;

(3) Poor contact between download cable and JTAG socket;

(4) The JTAG port of the download line and the board is connected reversely;

(5) FPGA burned;

(6) Power supply problems;

(7) There is a problem with the schematic design;

(8) The large pad at the bottom of the FPGA chip is not grounded.
my problem is 4.
I’m ashamed. In fact, try the opposite and find the position of the first JTAG pin (small semicircle).

ERROR Error: Cannot find module ‘../../uni-cli-sharedlib/tags‘

ERROR    Error:   Cannot   find   module  ‘../../ uni-cli-sharedlib/tags’

Recently, I ran the SVN project and reported an error. I tried many methods and various commands on the Internet

The last one found is that the NPM and node versions are incompatible

My node is 16.13.0

NPM is 8.13.1

The two versions are incompatible

The NPM version corresponding to node16.13.0 is 8.1.0

It can be solved by matching the version with this figure
