If you are looking for the solution of following error

ERROR: Could not install packages due to an EnvironmentError: [WinError 5] Acces s is denied: 'D:\softwares\spider\Lib\site-packages\libmysql.dll' Consider using the --user option or check the permissions.

The solution: You should add --user if you find an access-denied error.

 pip install --user mysql-connector-python

paste this command into cmd and solve your problem

I ran into the same problem as well   My problem was  that I accidentally installed the wrong connector version  Delete your currently installed version from your file system  my path looks like this  C  Program Files Python36 Lib site-packages  and then execute   pip install mysql-connector-python   This should solve your problem

I had this same issue but my resolution was different because this didn t completely work    I found this on a GitHub forum - copy and paste this into your terminal  You don t have to change your password  it can be the exact same    ALTER USER  root   localhost  IDENTIFIED BY  password  PASSWORD EXPIRE NEVER  ALTER USER  root   localhost  IDENTIFIED WITH mysql native password BY   NewPassword

To have a more permanent solution without going through your code and modifying whatever needs to be modified  Per MySQL 8 documentation  easiest way to fix this is to add the following to your MySQL d file -  restart MySQL server     This worked for me   If your MySQL installation must serve pre-8 0 clients and you encounter compatibility issues after upgrading to MySQL 8 0 or higher  the simplest way to address those issues and restore pre-8 0 compatibility is to reconfigure the server to revert to the previous default authentication plugin  mysql native password   For example  use these lines in the server option file    mysqld   add the following file to your MySQLd file     default authentication plugin mysql native password

I had the same problem and passing auth plugin  mysql native password  did not work  because I accidentally installed mysql-connector instead of mysql-connector-python  via pip3   Just leaving this here in case it helps someone

User · Answer

Per Caching SHA-2 Pluggable Authentication     In MySQL 8 0  caching sha2 password is the default authentication plugin rather than mysql native password    You re using mysql native password  which is no longer the default  Assuming you re using the correct connector for your version you need to specify the auth plugin argument when instantiating your connection object  cnx   mysql connector connect user  lcherukuri   password  password                                 host  127 0 0 1   database  test                                 auth plugin  mysql native password     From those same docs      The connect   method supports an auth plugin argument that can be used to force use of a particular plugin  For example  if the server is configured to use sha256 password by default and you want to connect to an account that authenticates using mysql native password  either connect using SSL or specify auth plugin  mysql native password

I was facing the same error for 2 days  then finally I found a solution  I checked for all the installed connectors using pip list and uninstalled all the connectors  In my case they were    mysql-connector mysql-connector-python mysql-connector-python-rf   Uninstalled them using pip uninstall mysql-connector and finally downloaded and installed the mysql-connector-python from MySQL official website and it works well
