Error in created hook: “typeerror: cannot read property ‘cm’ of undefined”
At the beginning, I put the initialization and instance of the map in the created hook function. As a result, I reported an error

Error in ODBC connection of Dameng database, [ISQL] error: could not SQLConnect
In the process of learning Dameng database, install ODBC driver process record.
Operating system environment: Qilin 6.0 server
1. UNIX ODBC installation
tar – xzvf UNIX odbc-2.3.0 tar.gz
CD unixodbc-2.3.0
./configure — enable GUI = no
make
make install
all the way down OK, there are two configuration files for ODBC configuration ODBC.ini and odbcinst.ini By default, you can log in and edit in/usr/local/etc
root user, as shown in the figure:
3. Test the ODBC connection
Su – dmdba
execute ISQL Dm7
report an error, [ISQL] error: could not SQLConnect
in order to see the cause of the error, execute ISQL – V Dm7, prompt:
according to the cause of the error, guess that there is an error in the configuration file. After careful inspection, it is found that:
after the problem is solved, execute ISQL Dm7, the correct result comes out:
Error: enoent: no such file or directory, stat ‘/ usr / local / var / www / /_ book/gitbook/git
Every time a gitbook is edited, there will be an error that causes the service that has been started through gitbook serve to stop. The error message is: error: enoent: no such file or directory, stat ‘/ usr/local/var/www//_ book/gitbook/gitbook-plugin-livereload/ plugin.js ‘
The background is that a new gitbook has been installed. Every time I edit the MD file in the project, I will hold the above error. As a result, the service I started through gitbook serve will stop and I can’t browse the edited gitbook normally
At the beginning, I didn’t care when I reported the error. The back office revised and edited the file several times, and found that the gitbook service would stop and report the above error after each modification. I found that this was not a mistake in my operation, but a problem with gitbok. After looking for the problem for a while, I didn’t have any idea, so I Baidu found out the bug in gitbook itself, The original configuration of gitbook is wrong. The specific modification method is as follows:
1. Find the configuration file address of gitbook (MAC system) in the user directory: Cd ~ to jump to the user directory of the current user
2. Find ~ /. Gitbook/versions/3.2.3/lib/output/website/ copyPluginAssets.js File, and then find all the confirm configuration items in this file (a total of 2 places), and change the original value of true to false
confirm: false
There are two places in total. Just change them
Python reported an error with keyerror: ‘longitude’
The error reporting interface of Python is shown in the following figure:
. I found a solution on the Internet, which may be useful to you. But I tried it, but it didn’t work. So when I looked at it, I found that it was caused by my carelessness. Ah, as shown in the figure below, there is a comma missing in front of longitude, as shown in the figure below:
, so this problem is solved. OK, I will continue my course design.
[Android] button uses the custom drawable file to set the background, and runs “error inflating class button”
(Android studio 3.1) when setting the background for the button control, the user-defined drawable file is used. No error is reported when running on Android 8.0, but an error is reported when running on Android 4.42. The error is as follows:


Finally, we find that when we switch to project mode, we can customize our own drawable file BT_ bg.xml The file is placed in the drawable-v24 folder, so BT_ bg.xml Move the file into the drawable folder (drawable-v24 can only be seen in project mode, but not in Android mode, as shown in the figure above). Run it again and the problem is solved.

IntelliJ idea solves Tomcat error: error listener start
When using idea, Tomcat can’t start normally, error prompt: org.apache.catalina . core.StandardContext.startInternal Error listener start. No more detailed error information.
Google has a plan to record Tomcat log details: create a new one in the project resource directory logging.properties File, enter the following into the file:
handlers = org.apache.juli.FileHandler,java.util.logging.ConsoleHandler
org.apache.juli.FileHandler.level = FINE
org.apache.juli.FileHandler.directory = ${catalina.base}/logs
org.apache.juli.FileHandler.prefix = error-debug.
java.util.logging.ConsoleHandler.level = FINE
java.util.logging.ConsoleHandler.formatter = java.util.logging.SimpleFormatter
Restart tomcat, you will find more detailed error information under server.
My error message here:
caused by: org.springframework.context . annotation.ConflictingBeanDefinitionException : Annotation-specified bean name ‘newsManagerController’ for bean class [ com.qf.official . controller.NewsManagerController ] conflicts with existing, non-compatible bean definition of same name and class [ com.qf.bookbar . news.controller.NewsManagerController ].
because the name of a class has been modified before, which is duplicate with the class name in the system, the problem is solved by modifying the class name.
