在项目子目录中运行 ESLint 会产生“堆内存不足”

Question

如果我从项目根目录运行

eslint .

，它会将所有错误和警告打印到控制台，正如我所期望的那样。

但是，当我

cd

进入项目的子目录时，

eslint .

会产生以下错误消息：

eslint 文档指出，

.eslintrc.js

适用于它所在的目录以及所有子目录。所以它应该使用相同的配置文件。

当它不必搜索整个项目时，理论上它不应该发现更少的警告吗？因此，我希望 eslint 也能使用更少的内存。

eslint 版本是

v7.26.0

。

Answer 1

增加

max_old_space_size

中的

NODE_OPTION

应该可以解决问题，按照 如何增加 EsLint 内存以避免“JavaScript 堆内存不足”？
