Three solutions for not generating QR codes after Vue deployment

When we reference some third-party libraries or plug-ins in the Vue project, sometimes we may encounter the problem that the QR code is not generated after deployment. This problem may cause us a lot of trouble and confusion, because QR codes have become a convenient and fast way to transmit information in the current mobile Internet era.

So, why is there a problem that the QR code is not generated after the Vue project is deployed? This may be related to some detailed operations we have during the deployment process. Below we will introduce several possible solutions.

Solution 1: Check whether the path is correct

In the Vue project, the QR code is generated by a third-party library or plug-in, so these third-party libraries or plug-ins should be ensured when deploying The path is configured correctly. If the path is incorrect, the generated QR code image will not be displayed correctly.

Solution 2: Check whether resource files are missing after deployment

Sometimes, when deploying a project, some resource files may be missing or not deployed correctly due to various reasons. This may also cause the QR code to fail to be generated properly.

Solution 3: Check whether the libraries or plug-ins the project depends on are installed correctly

Another reason that may cause the QR code not to be generated after deployment is that the libraries or plug-ins the project depends on are not installed correctly. Install. If we do not correctly execute instructions such as npm install or cnpm install to install the required dependent libraries after configuring the environment, this problem may occur.

Through the above three possible solutions, we can try to find the root causes of the QR code in our project that cannot be generated normally and solve them as soon as possible. This makes it easier to use QR code technology during project development and maintenance, saving time and improving efficiency.

Summary

It has become a common practice to use QR code technology in Vue projects, but it is also very common that the QR code is not generated after deployment. By carefully looking at and analyzing our code to find the root cause of the problem, we can try to solve the problem and save time and increase efficiency.
