Sharing a solution that helped me, try set your config variable like:
分享一个对我有帮助的解决方案，尝试设置您的配置变量，如：
$config['sess_save_path'] = sys_get_temp_dir();

change your application->config->config.php and set
更改您的 application->config->config.php 并设置
$config['sess_driver'] = 'database';
$config['sess_cookie_name'] = 'ci_session';
$config['sess_expiration'] = 7200;
$config['sess_save_path'] = 'ci_sessions';
$config['sess_match_ip'] = FALSE;
$config['sess_time_to_update'] = 300;
$config['sess_regenerate_destroy'] = FALSE;
& Run SQL query
& 运行 SQL 查询
CREATE TABLE IF NOT EXISTS `ci_sessions` (
`id` varchar(40) NOT NULL,
`ip_address` varchar(45) NOT NULL,
`timestamp` int(10) unsigned DEFAULT 0 NOT NULL,

In config.php sess_save_pathshould be sys_get_temp_dir();then it will resolve the error of mkdir(): Invalid path
在 config.phpsess_save_path应该是sys_get_temp_dir();然后它会解决的错误mkdir(): Invalid path
回答by Saty
The reason you encountered the error is because you didn't have a $config['sess_save_path']
您遇到错误的原因是因为您没有 $config['sess_save_path']
Go to you config.phpand set
去找你config.php并设置
$config['sess_save_path'] = NULL;

It can be due to PHP and codeIgniter version. For me, PHP 7.1.25 and CI 3.0.4 didn't work. You can check with session_id(). Session was refreshed. With CI 3.1.2 it works.
这可能是由于 PHP 和 codeIgniter 版本造成的。对我来说，PHP 7.1.25 和 CI 3.0.4 不起作用。您可以使用 session_id() 进行检查。会话已刷新。使用 CI 3.1.2 它可以工作。

Try this in your config.php
$config['sess_save_path'] = NULL
在你的 config.php 中试试这个
$config['sess_save_path'] = NULL
回答by Engr Syed Rowshan Ali
- Use absolute path for
$config['sess_save_path']in config file. - Point it to your writable temporary directory.
- Make sure the directory is under the directory allowed in apache or nginx config.
$config['sess_save_path']在配置文件中使用绝对路径。- 将其指向您的可写临时目录。
- 确保该目录位于 apache 或 nginx 配置中允许的目录下。

If $config['sess_save_path']is sys_get_temp_dir()then session data will store in system folder.
如果$config['sess_save_path']是，sys_get_temp_dir()则会话数据将存储在系统文件夹中。
And If you have database table as ci_sessions with below config.php:
如果你有数据库表作为 ci_sessions 与下面的 config.php：
$config['sess_driver'] = 'database';
$config['sess_cookie_name'] = 'ci_session';
$config['sess_driver'] = 'database';
$config['sess_cookie_name'] = 'ci_session';
The data will store in database. In this case you can $config['sess_save_path'] = NULL;
数据将存储在数据库中。在这种情况下，您可以$config['sess_save_path'] = NULL;

1.Open the config.php on application/config folder
1.打开application/config文件夹下的config.php
2.Browse all the way down to the $config['sess_save_path'] = NULL;line.
2.一直浏览到该$config['sess_save_path'] = NULL;行。
3.Change the NULLvalue to BASEPATH.'sessions'
3.将NULL值更改为BASEPATH.'sessions'

I had a similar case I have a multihost in godaddy and first I corrected the .htacces file
我有一个类似的案例，我在 Godaddy 中有一个多主机，首先我更正了 .htacces 文件
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_URI} ^system.*
RewriteRule ^(.*)$ /index.php?/ [L]
RewriteCond %{REQUEST_URI} ^application.*
RewriteRule ^(.*)$ /index.php?/ [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?/ [L]
</IfModule>
<IfModule !mod_rewrite.c>
ErrorDocument 404 /index.php
</IfModule>
Then correct the file config.php
然后更正文件config.php
$config['sess_driver'] = 'files';
$config['sess_cookie_name'] = 'ci_session';
$config['sess_expiration'] = 7200;
$config['sess_save_path'] = sys_get_temp_dir();
$config['sess_match_ip'] = FALSE;
$config['sess_time_to_update'] = 300;
$config['sess_regenerate_destroy'] = FALSE;
