Cannot read property ‘isFile‘ of undefined [How to Solve]

Today, when I started the project, I couldn’t get up. I always reported an error. After translation research, I came to the solution

When executing Vue project NPM run dev FileManager webpack plugin error typeerror: cannot read property 'isfile' of undefined

        if (isGlob) archive.glob(command.source, globOptions);else if (sStats.isFile()) archive.file(command.source, { 
        name: path$1.basename(command.source) });else if (sStats.isDirectory()) archive.glob('**/*', {

TypeError: Cannot read property 'isFile' of undefined
    at D:\abinwork\fmis_web\node_modules\filemanager-webpack-plugin\lib\index.js:271:79
    at D:\abinwork\fmis_web\node_modules\graceful-fs\polyfills.js:282:31

The reason for the error is very simple, because the project we just pulled down does not have a dist directory, and then FileManager webpack plugin find a dist directory and find that it does not exist, and then strike and quit, resulting in an error;

There are two solutions

First, you can repackage it;

npm run build

Second, modify the configuration and automatically create the dist directory when running

Note: look at the first step first. If you can run the NPM run build and then the NPM run dev project, you don’t have to perform the second step

plugins: [
    new FileManagerWebpackPlugin ({
      onEnd: {
        mkdir: [‘./dist‘],
        delete: [
        archive: [
          {source: ‘./dist‘, destination: ‘./dist.zip‘},

The probability is that the installed version of SCSS loader is too high

uninstall the original too high version and install the lower version

npm uninstall --save sass-loader // uninstall
npm i -D [email protected] // install
npm uninstall --save node-sass //uninstall

[Solved Perfectly] MySQL ERROR 1064 (42000): You have an error in your SQL syntax;

The perfect solution to error 1064

1064 error code appears when setting the root account password in MySQL

at first, I thought the user name and password could not be the same, so I changed it to 123456

and found it still couldn’t.


Enter as follows:

alter user 'root'@localhost identified by '123456';

By ‘…’ is followed by the new password.

Beeline connection hive2 reports an error permission denied

Error message:

Error: Could not open client transport with JDBC Uri: jdbc:hive2://localhost:10000:
Failed to open new session: 
Permission denied: user=anonymous, access=EXECUTE   , inode="/tmp":root:supergroup:drwx------

After trying to add an account and password to hive, it is found that the problem is stored in the last sentence. I am anonymous and the read-write permission of/tmp directory is drwx——

The first character: - indicates that this is a file, d indicates that this is a folder, | indicates that this is a connection file
is divided into three characters in a group
the first three: that is, RWX indicates owner permissions
the middle three: --- user permissions in the same group
the last three: --- other user permissions





specific role





the current user can read the file content and browse the directory


write write



the current user can add or modify file contents, and the current user can delete or move directories or files in directories





the current user can execute files and enter the directory

Aka, my root account is accessing hive2, so I belong to other user permissions, so I was rejected

Change the access permission of this file/file directory in the HDFS file system and relax it. The syntax of changing permissions is similar to that of Linux
HDFS DFS - Chmod - R 777/tmp log in with the account password of HDFS

failed call to cuInit: CUDA_ERROR_UNKNOWN: unknown error


It was good before. After restarting the computer running program, this error is reported:

Then it runs with the old slow CPU.

The probability is that the graphics card driver is stained with something.

Because I happened to update the system (Ubuntu) automatically before, I probably moved some NVIDIA files or something. Then I can’t restart.

Then I opened the Software Updater, completely updated it, restarted it, and finished it.

1. Cause of error: the password of the database connection is wrong, so it can be modified

I use the Nacos registry to check whether the password is correct in the configuration file application.properties

2. Reasons for error reporting  : The access port is occupied. Please refer to this document to release the port

3. Cause of error: the provider of remote call, the port of application.yml in the configuration file is wrong, and it is changed to the access port
