我尝试在ubuntu的文件夹中安装npm。当我这样做时，它有效，但它给了我警告。我要担心吗？
npm WARN deprecated joi@10.6.0: This version is no longer maintained. Please upgrade to the latest version. notes-app-api@1.1.0 /home/chana/notes-app-api
在底部它说：
npm WARN optional Skipping failed optional dependency /sane/fsevents:
npm WARN notsup Not compatible with your operating system or architecture: fsevents@1.2.7
npm WARN optional Skipping failed optional dependency /chokidar/fsevents:
npm WARN notsup Not compatible with your operating system or architecture: fsevents@1.2.7
npm WARN acorn-dynamic-import@4.0.0 requires a peer of acorn@^6.0.0 but none was installed.
然后当我从npm安装任何其他包时，会出现相同的警告。
