How to Fix

Failed to install mysqlclient: error "fatal error C1083: Cannot open file 'mysql.h': No such file or directory"

When installing the mysqlclient library using pip, you may encounter the following error message:

<code>fatal error C1083: Cannot open file: 'mysql.h': No such file or directory</code>

This error is usually caused by a missing mysql.h header file, which is essential for building the mysqlclient extension.

Solution

To resolve this issue, you can download the unofficial Windows binaries for your version of Python from this website. This method avoids the hassle of using the Visual Studio build tools.

Download the mysqlclient.whl file appropriate for your Python version.
Install the downloaded WHL file using the following command:

<code>pip install "下载文件的路径"</code>

For example, if you downloaded mysqlclient‑1.3.13‑cp36‑cp36m‑win_amd64.whl, you should execute the following command:

<code>pip install mysqlclient‑1.3.13‑cp36‑cp36m‑win_amd64.whl</code>

This method should successfully install the mysqlclient library without the above error.

MySQL: String Data Types and CollationsMay 09, 2025 am 12:08 AM

The string data types in MySQL include CHAR, VARCHAR, BINARY, VARBINARY, BLOB, and TEXT. The collations determine the comparison and sorting of strings. 1.CHAR is suitable for fixed-length strings, VARCHAR is suitable for variable-length strings. 2.BINARY and VARBINARY are used for binary data, and BLOB and TEXT are used for large object data. 3. Sorting rules such as utf8mb4_unicode_ci ignores upper and lower case and is suitable for user names; utf8mb4_bin is case sensitive and is suitable for fields that require precise comparison.
