这个错误是如何产生的呢? 启动mysql 为什么会报 The server quit without updating PID file(....pid ) 产生的原因有几种, 1:配置文件出现错误my.cnf 2:/usr/local/mysql/data 文件夹 的权限问题 3:进程已存在 mysql 的服务 首先 说说楼主的遭遇, 由于 配置 mysql 默认编码格式的时候出现配置错误, 导致 启动mysql (后来才想起来 我改过配置文件了) The server quit without updating PID file(updat file .....pid ) 悲催的折腾到2点多,google 查各种资料..于是便有了上面几个总结 问题1 的解决: 由于我当时脑抽了估计,居然改/usr/local/mysql/my.cnf 配置文件,导致后来才发现这里改动过了, 但是mysql 启动的时候,我觉得应该是这样进行查找my.cnf 的 首先 /etc/my.cnf 是否存在 if( true): 读取/etc/my.cnf else: 读取/usr/local/mysql/my.cnf | /usr/local/mysql/my.cnf~ 检查发现 my.cnf 没问题,于是问题1 忽略( 结果就是折腾到2点,忽略了/usr/local/mysql/my.cnf 的检查

I am writing a board game in Android where the UI consists of textViews for the scores (CPUScore and PlayerScore). The problem I have is that the UI does not update the score from its initial value when onCreate is called.

Everytime I start Spyder (with Anaconda) I get a massage saying that my version is outdated and I should update it, so I followed the instructions Spyder's own website gave me, which is running the following commands: conda update qt pyqt conda update spyder But Spyder tells me that syntax is invalid. What should I do? ( Spyder maintainer here ) Those commands are not meant to be run inside Spyder consoles, but in a system terminal ( cmd.exe on Windows, xterm on Linux or Terminal.app on macOS). And please don't forget to close Spyder before doing that. I updated the text in our Releases page
