[Solved] mongodb Startup Error: ERROR: child process failed, exited with error number 14

Mongodb used to work well before. Today, it suddenly started to report an error. According to the Internet, the possible reasons are:

1. failed to start when service mongodb restart
2. caused by not shutting down mongodb properly, such as direct kill -9 <pid> causes
3. locked by multiple threads when inserting data [may be too much data, space capacity is insufficient].

My solution:

Delete the mongod.lock file under dbpath, then delete all log files under logpath, and finally execute reboot to restart the server side.

[Solved] Error: Please select a valid Python interpreter

Before that

First download Python and configure environment variables

Win11python download and environment variable configuration

Python learning notes – error: Please select a valid Python interpreter

Question

The following error occurs when running: Please select a valid Python interpreter
the English meaning of this sentence: “please select a valid Python interpreter”

In fact, it’s because you just downloaded pychar, and you haven’t done its basic configuration yet. The error is normal ~

Solution:

First, Download python (again)

Open the DOS command line window,

ah, with ~

Then, the parser selects the problem, opens settings (Ctrl + Alt + s) or file & gt; settings, and opens the configuration box, as shown in the following figure:

Just follow the steps:

The results are shown in the figure below:

Then you can!

[Solved] AttributeError: ‘DataFrame‘ object has no attribute ‘tolist‘

 

solve the problem

return object.__getattribute__(self, name)
AttributeError: ‘DataFrame’ object has no attribute ‘tolist’

Solution ideas

Property error: ‘dataframe’ object does not have property ‘tolist’

Solution:

Remember that DataFrame does not have a tolist() method, but series.Series has a tolist() method, so it needs to be modified

take

import pandas as pd

#Read xls file
file_path='data/test1226.xls'
data_frame_xls=pd.read_excel(file_path)
data_df01 = data_frame_xls[['age']]
print(type(data_df01))
print(res)

Change to

import pandas as pd

#Read xls file
file_path='data/test1226.xls'
data_frame_xls=pd.read_excel(file_path)
data_df01 = data_frame_xls[['age']]
print(type(data_df01))

data_df01 = data_frame_xls['age']
print(type(data_df01 ))
res = data_df01 .tolist()
print(res)

Ha ha, it’s done!

CMake Error :MYSQL_INCLUDE_DIR [How to Solve]

CMake Error: The following variables are used in this project, but they are set to NOTFOUND.
Please set them or make sure they are set and tested correctly in the CMake files:
xxxx/MYSQL_INCLUDE_DIR

Solution: yum install mysql-devel

Other missing boost/cmake etc. can be installed by compiling the source code.

cmake-3.8.2.tar.gz
boost_1_78_0.tar.gz

error: stray ‘\343’ in program [How to Solve]

Problem phenomenon:

Cause of problem:

This error is basically generated by copying the code from the web page and compiling it. Because the copied code contains Chinese spaces and characters, it can’t be distinguished by the naked eye.

Solution:

1. When the amount of code is small, it is best to re type it at the error location, then save it and recompile it.

Error prompts the location information of the error. Find the corresponding place to change.

2. It can also be used when there are many codes, or the replacement function of GEDIT can be used to replace with standard spaces, which is more labor-saving.

Find characters in error:

Under Linux, you can:

cat xxx.c -A

Chinese will be displayed as characters with red lines.

Dubbo Frame Write Junit Error: ERROR org.springframework.test.context.Testcontextmanager

Solution:

Since the Dubbo framework is used, on the premise that we confirm that there is no problem with JUnit unit test environment:

First, check whether the Dubbo service is enabled; Secondly, if the test class is written in the consumer module, you need to check whether the provider service is enabled;

Start the corresponding service to solve the problem.

Detailed error reporting information is as follows:
