The above problem is that there is a problem with the dev environment. After closing dev, open it again and you will be prompted

Solution, reinstall dev

2. Click build ->Default Compiler

Switch to xelatex

[Solved] SyntaxError:JSON.parse:unexpected character at line 1 column 1 of the JSON data

Controller code:

Front end Ajax request code:

The status code 200 indicates that the request is successful, but the pop-up window (data returned by the server) cannot be received

Question tips:

SyntaxError:JSON. parse:unexpected character at line 1 column 1 of the JSON data

It is speculated that there was an error in parsing JSON data. The server wanted to use the string as JSON, but the format conversion failed

The reason is that I set the datatype in the Ajax request to “JSON”. JQuery will convert the string in the resp to JSON format according to this, but the conversion fails. Just comment out this line.

[Solved] error Strings must use singlequote, error Extra semicolon、error Unexpected trailing comma

After formatting the code, single quotation marks will be changed into double quotation marks, and a comma will be added at the end. The semicolon at the end will lead to three kinds of errors:

1 Strings must use singlequote Quotes – double quotes
2 Extra semicolon semi — semicolon at the end
3 Error unexpected trailing comma comma Dangle — comma

[Solved] Clickhouse Error: DB::Exception: Cannot lock file /var/lib/clickhouse/status

1、 Problem description

After the Clickhouse is started, it can be accessed by itself. There is no problem, and it can also be accessed externally. However, check its error log and find that there are always errors

tail -f clickhouse-server/clickhouse-server.err.log
output:
2020.10.07 19:05:32.720350 [ 8150 ] {} <Error> Application: DB::Exception: Cannot lock file /var/lib/clickhouse/status. Another server instance in same directory is already running.
2020.10.07 19:06:02.970577 [ 8217 ] {} <Error> Application: DB::Exception: Cannot lock file /var/lib/clickhouse/status. Another server instance in same directory is already running.
2020.10.07 19:06:33.220827 [ 8632 ] {} <Error> Application: DB::Exception: Cannot lock file /var/lib/clickhouse/status. Another server instance in same directory is already running.
2020.10.07 19:07:03.471225 [ 8706 ] {} <Error> Application: DB::Exception: Cannot lock file /var/lib/clickhouse/status. Another server instance in same directory is already running.
2020.10.07 19:07:33.720339 [ 8880 ] {} <Error> Application: DB::Exception: Cannot lock file /var/lib/clickhouse/status. Another server instance in same directory is already running.
...

It doesn’t stop, so it’s embarrassing.

2. Problem-solving

After probing, the Clickhouse server may have been started twice before. Therefore, check the status file directly according to the log directory

cat /var/lib/clickhouse/status
ps -ef | grep clickhouse-server
Delete the corresponding clickhouse-server
kill -9 $pid
systemctl start clickhouse-server

Then, check the error log again, and it’s OK

tail -f clickhouse-server/clickhouse-server.err.log

[Solved] Prittier format code error: JSON Error in…

Error screenshot

[error] Invalid configuration file `src\index.js`: JSON Error in E:\202112\testPrettier\.prettierrc.json: 
[error]
[error] > 1 | ��
[error]     | ^
[error]
[error] Unexpected token "�" (0xFFFD) in JSON at position 0 while parsing "��"
[error]
[error] > 1 | ��
[error]     | ^
[error]

Installation process

Install prettier 

yarn add --dev --exact prettier

Create .Prettier.json

echo {}> .prettierrc.json

Create .prettierignore

echo {}> .prettierignore
# write content
src/assets
**/*.md
**/*.svg
**/*.html
**/*.ejs
**/*.png
**/*.eot
**/*.woff
**/*.ttf
**/*.gif
**/*.jpg
**/*.jpeg
package.json

Execute yarn prettier --write ., an error will be report:

Check the index.js in prettier as following:

searchPlaces: ["package.json", ".prettierrc", ".prettierrc.json", ".prettierrc.yaml", ".prettierrc.yml", ".prettierrc.json5", ".prettierrc.js", ".prettierrc.cjs", "prettier.config.js", "prettier.config.cjs", ".prettierrc.toml"],
loaders: {
      ".toml": loadToml,
      ".json5": loadJson5
    }

More than one name was found prettierrc.JSON format file

Solution:

Replace  prettier.json file with pretierrc.config.js  file and write its internal contents in the following way:

module.exports = {
    trailingComma: "es5",
    tabWidth: 4,
    semi: false,
    singleQuote: true,
};

You can format the file. I don’t understand why.

Combined with husky, the project automatically formats the code before submitting GIT

Premise: the project must be git controlled, otherwise the following will report an error and install lint staged

npx mrm@2 lint-staged

This is a relatively simple and fast way

Python Pandas Error: KeyError: 0 [How to Solve]

Keyerror: error reported by 0

The following are error codes

I call my own library function and use apply to realize vlookup in Excel. The following is the code

data2 = super_function.vlook_up(data1, ['material group', 'material description'], data, ['material group', 'material group description'])

Error message

KeyError: 0

Error reporting reason

This kind of error reporting is due to the index problem. As a result, some numbers were deleted during the original data processing, resulting in the index starting from 6 instead of 0.

Solution:

Just reassign the index

data1.index = list(range(len(data1)))

result

Run successfully.
