無法安裝 MySQL-python

Question

我想在 python 2.7 虛擬環境中安裝 MySQL-python，但出現以下錯誤：

Installing collected packages: MySQL-python
Running setup.py install for MySQL-python ... error

我已經嘗試安裝這篇文章和這篇文章中建議的解決方案

Answer 1

所以我設法用以下命令解決了這個問題：

sudo wget https://raw.githubusercontent.com/paulfitz/mysql-connector-c/master/include/my_config.h -P /usr/include/mysql/

我從對此答案的評論中發現。

Answer 2

According to the MySQL 8 docs:https://dev.mysql.com/doc/relnotes/mysql/8.0/en/news-8-0-2.html

這些更改是針對客戶程序開發進行的：

客戶端程序應該只需要#include <mysql.h> header 文件。 特別是，應該不需要 <my_config.h> 並且不再安裝。

因此， libmysqlclient-dev的新安裝可能會因此排除my_config.h 。

然而，這也暗示了一個非常簡單的答案——當一個程序試圖包含my_config.h時，給他們mysql.h代替：

sudo apt install libmysqlclient-dev
sudo ln -s /usr/include/mysql/mysql.h /usr/include/mysql/my_config.h

我能夠pip install MySQL-python==1.2.5並添加了該軟鏈接。
