为什么我的 Jest 一跑就会挂掉,错误提示一会儿是 out of memory,一会儿是 EPIPE

    这是一个创建于 1588 天前的主题,其中的信息可能已经有所发展或是发生改变。

    windows 10 (1709)

    node 10.19.0

    Jest 26.0.1

    机器有 32g 内存。编译和运行都没有问题,就是 jest 无法正常跑完。

    这个是咋回事儿,没有头绪呢。

    在 macos 下跑 jest 就没有问题

    Let me Google that for you?

    https://stackoverflow.com/q/38558989/2221631 看看能不能解决。

    换个 node 大版本
    看看 Jest 周边的一些库是不是没有升到新版本
    改变一下测试的数量,从 1 个开始
    改变一下并行 worker 的数量
    在 wsl 底下跑

    都试试看

    都 32G 了就给进程多分点内存呗。

    @seki #3 只跑一个 test,或者一个 suite 都没问题。
    知道统一跑,就不行了。

    另,怎么设定 worker 等参数?
