virtual memory exhausted: Cannot allocate memory

Server, 1G memory Alibaba Cloud server, it should be enough to compile things, and install related content without any problem, but after compiling for a while, I encountered the problem of virtual memory exhausted: Cannot allocate memory.

Solution

This problem occurs because the server does not have enough memory, causing the compilation to fail.

The Alibaba Cloud server you purchased does not allocate virtual memory to you, so you can solve the problem by increasing the virtual memory yourself:
