Another error was reported during Android development. This is a version error. The first step is to synchronize the versions
error message:
Android studio error: gradle project sync failed. Please fix your project and try again
1. Version synchronization:
1.1 file> sync project with android gradle
If you succeed, you don’t have to look at the following
1.2 error reporting:
It can be seen or not solved:
It should be the version problem. If we can’t download it, we can download it directly manually (check the network first, and the agent has no problem, but it still can’t be solved)
2. Modify proxy parameters:
Agent:
2.1 open file> setting> Search proxy
2.2 configuration information
The address and port of the agent shall be filled in as follows:
URL: http://127.0.0.1:1080/pac
2.3 check whether the Ping is connected
Still not!
3. Manual Download
So let’s continue:
3.1 open the gradle wrapper properties file
3.2 download
Download the gradle in the last line of the website. Note that the version must be consistent. Download whatever he puts down.
3.3 modifying environment variables
Remember to modify the gradle environment variable in the computer:
3.4 modify the compilation environment configuration
Then unzip it, modify the gradle configuration in the environment, and it’s OK.
You can see that my environment is OK now:
1. After using idea to create a spring project, it is found that the spring boot Maven plugin in pom.xml reports an error.
2. Compared with the springboot project created on the official website, it is found that < version> 2.4.12
3. Add the corresponding version to idea
Conclusion: the problem that is not a problem is the most people’s mentality

Invalid resource handle error in pycuda code
When running CUDA code, the following error occurs:
File "/mnt/lustre/demo/extract_disp_newtopo/face_registration-master/code/poisson.py", line 147, in blend_gs_cuda
block = (1024, 1, 1))
File "/mnt/lustre/miniconda3/envs/pycuda/lib/python3.6/site-packages/pycuda/driver.py", line 436, in function_call
func._set_block_shape(*block)
pycuda._driver.LogicError: cuFuncSetBlockShape failed: invalid resource handle
Solution:
find the CUDA function part with the problem:
mod = SourceModule("""
#include <stdint.h>
__global__ void construct_b(
const uint8_t* src, const int16_t* u, const int16_t* v,
float* b,
int pix_num, int size
)
You can add any sentence in the following code before the function declaration
src = torch.cuda.ByteTensor(8)# Fill in the numbers at will, and the matrix is also fine, but the data type should be consistent with the data type in C++
b = torch.cuda.FloatTensor(9)
The complete code is as follows:
src = torch.cuda.ByteTensor(8)
mod = SourceModule("""
#include <stdint.h>
__global__ void construct_b(
const uint8_t* src, const int16_t* u, const int16_t* v,
float* b,
int pix_num, int size
)
The specific reason is unknown because it occurs occasionally.
In the egg project, NPM is installed for the first time The following errors are reported when the package is:
Oops! Something went wrong! :(
ESLint: 5.16.0.
ESLint couldn't find the plugin "eslint-plugin-jsdoc". This can happen for a couple different reasons:
1. If ESLint is installed globally, then make sure eslint-plugin-jsdoc is also installed globally. A globally-installed ESLint cannot find a locally-installed plugin.
2. If ESLint is installed locally, then it's likely that the plugin isn't installed correctly. Try reinstalling by running the following:
npm i eslint-plugin-jsdoc@latest --save-dev
Path to ESLint package: /Users/***/node_modules/eslint
If you still can't figure out the problem, please stop by https://gitter.im/eslint/eslint to chat with the team.The eslint does not work normally, and when the file does not comply with the eslint rules, an error is reported in the console log as follows:
Failed to load plugin jsdoc: Cannot find module 'eslint-plugin-jsdoc'....reason:
When NPM v8.0 installed the project dependency, it did not correctly install the project dependency (eslint config egg) dependency (eslint plugin JSDoc)
solve:
After upgrading NPM to v8.1.2, delete the node in the project_ Modules and package-lock.json, and then reinstall
rm -rf node_modules
rm package-lock.json
npm iSupplement:
If you have the same error, you can search globally Eslint plugin JSDoc to locate dependencies with NPM command
➜ *** git:(master) ✗ npm ls eslint-plugin-jsdoc
***@1.0.0 /Users/***
└─┬ [email protected]
└── [email protected]Then determine whether to install or upgrade NPM manually or for other reasons.

The reason for this problem is.
It is not correct to write this below.
It should look like this.
If there is an error, solve it: ‘action’ is defined but never used no unused vars
* * error reason: * * because the built Vue project selects the eslint verification specification -> The eslint specification is that you either don’t define a variable or you must use it if you define it
Solution:
Add the following code into the package.json file (restart the project after saving!!!)
"rules": {
"generator-star-spacing": "off",
"no-tabs":"off",
"no-unused-vars":"off",
"no-console":"off",
"no-irregular-whitespace":"off",
"no-debugger": "off"
}

Correct practice

In the process of writing request headers, the use of headers did not notice the case problem!!!
During a project development, the front-end uploaded a file and reported a bug without permission
Problem description
Request processing failed; nested exception is org.springframework.web.multipart.MultipartException: Failed to parse multipart servlet request; Needed exception is org.apache.commons.fileupload.fileuploadbase $iofileuploadexception: processing of multipart/form data request failed
Error reporting reason
It should be because HTTP remote access does not have permission to access the temporary directory of Tomcat on the server
So we might as well directly set a temporary file upload path instead of using the default path of Tomcat
Solution:
Modify the uploaded temporary file path instead of the default temporary file path of Tomcat
When uploading the configuration file in applicationcontext.xml of spring, add
<property name="uploadTempDir" value="/temp"/>
The content in value is the temporary file directory you want to set
