2. Solution

All kinds of data say that node memory overflow , and solutions are also given,
for example: – max_old_space_Size = 4096 and so on, but it doesn’t work for me. (if you refer to mine, it doesn’t work, you can look at the other methods mentioned above)
later, I saw a solution, which worked
1, CMD Global install increase memory limit
NPM install -g increase memory limit

2, CD enter the project directory and execute:
increase memory limit

3. Repack
NPM run build
