以root身份拷贝了一个.py文件到/use/bin/python.导致mac自带的python2.7不能用了，运行不了python程序。

Posted 2023-04-27

各种搞不定，特来百度求大神帮忙，只要不重装就行。

参考技术A /use/bin/python不是文件夹而是python的执行文件。
你实际上是把.py文件重命名为python文件。导致python主程序被替换。
python当然就不能运行了。
这样的情况下，只能重装python。
或者到别的mac机上复制一个/usr/bin/python文件到你的机上。 参考技术B 新拷贝的py文件名字不对，占用了关键字。重新改个个性的名字。

没有密码就无法以root身份登录phpmyadmin [关闭]

【中文标题】没有密码就无法以root身份登录phpmyadmin [关闭]

【英文标题】：Cant login as root with no password to phpmyadmin [closed]

【问题描述】：

这是我的 config.inc.php 文件，因为我突然升级到 11.10，我无法在没有密码的情况下以 root 身份登录。我已经正确设置了指令，所以这对于它为什么不再允许这样做是相当令人困惑的。有什么帮助吗？

【问题讨论】：

我有 phpMyAdmin 11.10，我可以使用 root 登录，无需密码。看起来它是针对您的。

是的，令人困惑，但正如您所见，在底部“AllowNoPassword”TRUE 附近有第二条注释行……所以我也取消了注释。现在我是 gtg。

【参考方案1】：

底部附近还有第二行：

/* Uncomment the following to enable logging in to passwordless accounts,
 * after taking note of the associated security risks. */
// $cfg['Servers'][$i]['AllowNoPassword'] = TRUE;

这一行也需要取消注释。
