Error when starting Python in Windows

Error message

Start Python 3.6 in the windows command line environment and report the following error

C:\Users\gaozh>python

UnicodeDecodeError: 'gbk' codec can't decode byte 0x80 in position 407: illegal multibyte sequence

terms of settlement

The way to solve this problem is to modify the corresponding code in line 82 of the file C: \ anaconda3 \ lib \ site packages \ pyreadline \ lineeditor \ history. Py , add the coding format as UTF-8 , and then restart python.

Someone is experiencing the same problem when upgrading to jdk9

By adding startup parameters

--add-opens java.base/java.lang=ALL-UNNAMED

Original information

The following error message appears:

Exception in thread “main”
java.lang.reflect.InaccessibleObjectException: Unable to make field
private static final long java.lang.Long.serialVersionUID accessible:

at java.base/java.lang.reflect.Field.setAccessible(Field.java:165)
at com.jdojo.intruder.TestManifestAttributes.main(TestManifestAttributes.java:10)
A runtime error indicates that the application cannot access the private static serialVersionUID because the java.lang package in the java.base module is not open. Let’s try the – add opens option first:

C: \ java9revealed & gt; Java — add opens Java. Base/Java. Lang = all unnamed
– jar com.jdojo.intruder \ dist \ com.jdojo.intruder.jar output information is as follows:

Long. SerialVersionUID = 4290774380558885855 this command works normally and verify that the command line option is the solution in this case.
we use the add opens attribute in the manifest.mf file to fix this error, as shown below.

Manifest version: 1.0 main class:
com.jdojo.intruder.testmanifestattributes add opens:
java.base/java.lang recreate the executable jar and run it with the same command:

C: \ java9revealed & gt; Java – jar
com.jdojo.intruder \ dist \ com.jdojo.intruder.jar the output result is:

Long.serialVersionUID=4290774380558885855

Run the project again and query the data successfully

Summary: upgrading from java11 to java17 is a personal computer at home, not a production environment,

It takes about 5 hours to solve the problem, because the project is a shared research project, involving many knowledge points, and it takes a long time to locate the problem.

Difficult: the project itself has no problem starting jdk11, but an error is reported after upgrading jdk15.

Error in installing paddlenlp on pip on Windows

1. PIP installation paddlenlp reports an error

An error is reported when PIP installs paddlenlp on windows, as follows:

 distutils.errors.DistutilsError: Command '['C:\\Users\\yuanyangping\\.conda\\envs\\yyp_paddle\\python.exe', '-m', 'pip', '--disable-pip-version-check', 'wheel', '--no-deps', '-w', 'C:\\Users\\YUANYA~1\\AppData\\Local\\Temp\\tmphix_2c5i', '--quiet', 'setuptools_scm']' returned non-zero exit status 1.

Some methods to solve the problem are queried, but they are not effective, so they are not listed one by one.

2. Solutions

Pay attention to one detail. It is normal to download paddlenlp, but an error is reported only after downloading seqeval, as follows:

Collecting paddlenlp
  Downloading http://mirrors.aliyun.com/pypi/packages/b0/7d/6c24cda54d018d350ee342f715523ade7871660444ed95f3d3e753d6f388/paddlenlp-2.0.8-py3-none-any.whl (571 kB)

     |████████████████████████████████| 43 kB 656 kB/s
    ERROR: Command errored out with exit status 1:

Therefore, can you install seqeval first and then paddlenlp, and execute two commands in succession, as follows:

pip install seqeval
pip install paddlenlp

Then paddlenlp is successfully installed
If an error is still reported, specify the version of seqeval as 0.0.3

3. Extension

The above reason should be that there is a problem with the configuration information when downloading and installing seqeval
therefore, if similar error reports occur when installing other software, you can install the software where the error is reported first, and then install the main software you want to install.

Typescript generic source code error

1. The error information is as follows

2. Source code understanding

export declare type InputProps = Pick<React.DetailedHTMLProps<React.InputHTMLAttributes<HTMLInputElement>, HTMLInputElement>, 'maxLength' | 'autoComplete' | 'enterKeyHint' | 'pattern' | 'type' | 'onFocus' | 'onBlur' | 'autoCapitalize' | 'autoCorrect'> & {
    value?: string;
    defaultValue?: string;
    onChange?: (val: string) => void;
    placeholder?: string;
    disabled?: boolean;
    readOnly?: boolean;
    clearable?: boolean;
    onClear?: () => void;
    id?: string;
} & NativeProps<'--font-size' | '--color' | '--placeholder-color' | '--disabled-color'>;

React.inputhtmlattributes have the following names in react

type DetailedHTMLProps<E extends HTMLAttributes<T>, T> = ClassAttributes<T> & E;

3. Solution

The version of react declaration file is too low. The following declaration is missing

Initialization of bean failed； nested exception is java.lang.StackOverflowError

Too many assemblies in mybatis spring mapper cause stackoverflow
