Revealing the method to solve PyCharm key failure

PyCharm is a powerful Python integrated development environment that is widely loved by developers. However, sometimes we may encounter key invalidation problems when using PyCharm, resulting in the inability to use the software normally. This article will reveal the solution to PyCharm key failure and provide specific code examples to help readers quickly solve this problem.

Before we start to solve the problem, we first need to understand the reason why the key is invalid. PyCharm key failure is usually caused by network problems or updates to the software itself. When PyCharm cannot verify the key, a prompt such as "Your license has expired" or "License server can't be reached" will appear. Next, we'll cover several common solutions along with specific code examples.

Solution 1: Reactivate using the activation code

First, we can try to reactivate PyCharm using the activation code. In the PyCharm activation interface, select "Activate" and then enter the new activation code. If the previous activation code is invalid, you can contact PyCharm official to obtain a new activation code.

# 代码示例：重新激活PyCharm
activate_code = "your_new_activate_code"
pycharm.activate(activate_code)

Solution 2: Block verification through hosts file

If we cannot obtain a new activation code, we can block PyCharm’s verification request by modifying the hosts file. Find the location of the hosts file (usually located in C:WindowsSystem32driversetchosts), add the following content and save:

0.0.0.0 account.jetbrains.com
0.0.0.0 www.jetbrains.com

In this way, PyCharm will be unable to connect to the verification server during verification, thus bypassing key verification.

Solution 3: Modify the hosts file to point to the local

Another method is to point the verification server address in the hosts file to the local so that PyCharm will connect during verification to local rather than external server. Edit the hosts file, add the following content and save it:

127.0.0.1 account.jetbrains.com
127.0.0.1 www.jetbrains.com

Then build a simple HTTP server locally, listening to the 127.0.0.1 address, to pretend to be a verification server. In this way, PyCharm will connect to the local server during verification to achieve local verification.

The above are three common methods to solve the problem of PyCharm key failure. Readers can choose the appropriate method to solve it according to their own situation. I hope these solutions and code examples can help everyone and enable you to successfully use PyCharm for development work.
