Window 环境安装 Mycli

平时都用图形化界面操作MySQL 如 navicat, workbench. 为了更专业一点也锻炼一下动手能力，现在打算换成命令行的方式操作。了解到 myclli这个工具。方便体验，就先在window环境装一个玩玩。

mycli 是一个 MySQL 命令行客户端工具，具有自动完成和语法突出显示功能。
它是基于 python 开发的一个工具，适合初学者或者对数据库熟悉但命令记不住的人群，能很好地克服记不住命令的困难。 mycli 官网地址

一、Python 3 安装

官网下载地址(windows版本)：Python Releases for Windows | Python.org
推荐下载 windows-installer-64 bit, embaddable-XXX前缀的是绿色免安装版
下载后直接双击exe文件，进入图形界面，安装模式选择 customize installation(用户自定义安装), 不建议勾选Add Python XX to PATH,勾选后去环境变量里找很难找到，安装完自己去手动添加环境变量即可，后续无脑next，记得换安装路径。
python 卸载，如果安装错了，重新点击刚刚下载的python安装exe，选择 uninstall 即可干净卸载，然后再重新安装。
安装完成后，配置好系统环境变量 ,python安装的目录，及其下一层级的 Scripts目录，注意把 windowsApps这个往下移动，否则配置好后，到cmd 命令行窗口输入 python 会奇怪的打开 window应用商店…

测试 python 安装: 打开cmd 命令行输入 python 打印如下内容即安装完成，环境变量也生效了

PS C:\Users\lvzb3> python
Python 3.11.1 (tags/v3.11.1:a7a450f, Dec  6 2022, 19:58:39) [MSC v.1934 64 bit (AMD64)] on win32

二、Mycli 安装

python 安装完成后，即可安装 mycli, pip install mycli。注意官网参考资料中： Installing & Using MyCli on Windows - Code Wall，使用的命令是 pip install -U mycli, 我在使用时，报错了：Could not install packages due to an OSError:XXXXXXX 。

D:\software\mycli>pip install mycli

四、遇到的问题及解决

（一）`pip install -U mycli`报错

解决：使用 pip install mycli

D:\software\mycli>pip install -U mycli

(connect timeout=15)'))

（二）less 不是内部或外部命令，也不是可运行的程序或批处理文件

解决：

you can open up myclirc file located under C:\Users\<username>\.myclirc and set enable_pager = False. This will turn off using less for output. 去C盘用户目录下的 .myclirc 把 enable_pager = False 即可解决
