ReactJS Start/build内存溢出_react-scripts build 内存

1.执行start命令或者build命令内存溢出问题

.FATAL ERROR: CALL_AND_RETRY_LAST Allocation failed - JavaScript heap out of memory

1.1使用的scripts脚本命令如下:

"scripts": {
"clean": "rimraf dist",
"start": "better-npm-run start",
"deploy:prod": "better-npm-run deploy:prod",
"codecov": "cat coverage/*/lcov.info | codecov",
"snippet": "node snippet"
},

.无论使用start本地命令还是执行deploy:prod 打包命令,均报*FATAL ERROR: CALL_AND_RETRY_LAST Allocation failed - JavaScript heap out of memory
*错误,详细如下所示:

错误信息就如上面展示的这样,查看了活动指示器node分配的内存最大到1.5g的时候就无法增长,本人32g的电脑运存.其实就是在执行打包/启动命令的时候,所需要的内存大于1.5g,而默认分配的最多1.5g,就会导致这个问题

1.2在使用打包/启动命令的时候,增加内存参数,

• 1.2.1 增加内存方式1:
