Vue el-table Error: Duplicated keys detected This may casuse an update error
Errors are similar to
The component used is El table. Combined with the prompt in the figure, the key should be repeated when TL table renders the row node again.
El table has an EL key attribute. My assignment is: row key = “step”_ id”
Combined with data, step_ ID does have a duplicate. Replace with:
row-key=”id”
A key value that will not be repeated will solve the problem.
Error: listen eaddnotavail: address not available
preface:
Build a distributed project, find a front-end project of Vue framework to do interface test, use nodejs to report error: listen eaddnotavail: address not available.
Problem analysis:
After the above error, there are still some error statements below. Here I show that IP and port number cannot be monitored.
Problem solving:
Modify the conf file under the Vue project, that is, under the configuration file, connect the IP and port of the background and the IP and port of the host. Configure IP to cost machine or IP address needed by the project, and solve the problem.
