Magento2-2.3.4 windows安装完magento无法加载静态资源导致无法进入后台登录页面

后台面无法进入，截图如下

首先查看var/log/system.log日志文件，发现报错信息如下

解决方法

找到libinternalMagentoFrameworkViewElementTemplateFileValidator.php文件中的isPathInDirectories方法

$realPath = str_replace('\', '/', $this->fileDriver->getRealPath($path));替换$realPath = $this->fileDriver->getRealPath($path);

看结果

如果还是不行，可以尝试如下操作

INSERT INTO core_config_data (path, value) VALUES ('dev/static/sign', 0) ON DUPLICATE KEY UPDATE value = 0;

php bin/magento cache:clean

如果登录页面可以打开，但是图片和CSS报404，可以执行正面命令

sudo php bin/magento setup:static-content:deploy -f
sudo php bin/magento cache:flush

如果登录页面打不开只显示No input file specified.

请检查 var/cache缓存目录是否有写入权限，如果没有执行正面命令

sudo chmod 777 var/cache -R

 如果登录页面打不开，然后exception报class not exist,执行正面命令

sudo php bin/magento setup:di:compile
sudo php bin/magento cache:flush
