ENOSYS：功能未实现

Question

我最近在 raspbian 操作系统的 raspi 4 中安装了 next js use to npm。每次我安装react js，next js，gatsby都会给我同样的错误。

---

这时候我安装nextjs 使用yarn。另外，我使用 npm 和 npx 来显示相同​​的错误。所以我开始寻找解决方案然后有人告诉我使用 sudo 所以我使用 sudo 但不起作用

sudo yarn create next-app

检查我的代码错误输出

Answer 1

你可以试试这个：

1. 删除 yarn.lock。
2. 删除 node_modules。
3. 使用 --ignore-optional 标志 (yarn --ignore-optional);这些不安装可选依赖项。

fsevents 包仅适用于 macOS；在 Linux 中你不需要它。

如果其中任何一个有效，您可以删除 ignore 并查看 .yarnclean 是否有效。

Answer 2

根据日志，脚本似乎无法创建符号链接

"ENOSYS: function not implemented, symlink '../../../../terser/bin/terser' -> '/media/pi/8243-BE00/next/myapp/node_modules/@ampproject/toolbox-optimizer/node_modules/.bin/terser'".

您使用的文件系统是什么？我知道 exFAT 和 FAT32 不支持符号链接。
