【问题描述】：

当我创建一个新的 Angular 项目时，我从 NPM 收到这些警告：

        npm WARN optional SKIPPING OPTIONAL DEPENDENCY: fsevents@1.2.9 (node_modules/webpack-dev-server/node_modules/fsevents):
        npm WARN notsup SKIPPING OPTIONAL DEPENDENCY: Unsupported platform for fsevents@1.2.9: wanted {"os":"darwin","arch":"any"} (current: {"os":"linux","arch":"x64"})
        npm WARN optional SKIPPING OPTIONAL DEPENDENCY: fsevents@1.2.9 (node_modules/watchpack/node_modules/fsevents):

        npm WARN notsup SKIPPING OPTIONAL DEPENDENCY: Unsupported platform for fsevents@1.2.9: wanted {"os":"darwin","arch":"any"} (current: {"os":"linux","arch":"x64"})
        npm WARN optional SKIPPING OPTIONAL DEPENDENCY: fsevents@1.2.9 (node_modules/@angular/compiler-cli/node_modules/fsevents):
        npm WARN notsup SKIPPING OPTIONAL DEPENDENCY: Unsupported platform for fsevents@1.2.9: wanted {"os":"darwin","arch":"any"} (current: {"os":"linux","arch":"x64"})
        npm WARN optional SKIPPING OPTIONAL DEPENDENCY: fsevents@2.0.7 (node_modules/fsevents):
        npm WARN notsup SKIPPING OPTIONAL DEPENDENCY: Unsupported platform for fsevents@2.0.7: wanted {"os":"darwin","arch":"any"} (current: {"os":"linux","arch":"x64"})

似乎它们无关紧要，因为该项目与ng serve -o 配合得很好。有没有办法关闭这些？

这是我的ng --version 结果：

【解决方案1】：

您可以尝试将这些选项添加到 npm install 命令：

--no-optional argument will prevent optional dependencies from being installed. --no-shrinkwrap argument, which will ignore an available package lock or shrinkwrap file and use the package.json instead. --no-package-lock argument will prevent npm from creating a package-lock.json file.
