在 ubuntu 16.04 nodejs v4.2.6 npm 3.5.2 上安装 web-ext 后无法 运行 插件

Question

在安装 web-ext 时，我在安装过程中收到了这两条消息：

npm WARN optional Skipping failed optional dependency /web-ext/chokidar/fsevents:
npm WARN notsup Not compatible with your operating system or architecture: fsevents@1.2.4

尝试使用 web-ext run 启动插件后，我收到此消息

TypeError: Cannot read property 'R_OK' of undefined at fileIsReadable (/usr/local/lib/node_modules/web-ext/dist/webpack:/src/util/file-exists.js:24:42) at _callee$ (/usr/local/lib/node_modules/web-ext/dist/webpack:/src/util/file-exists.js:28:11) at tryCatch (/usr/local/lib/node_modules/web-ext/node_modules/regenerator-runtime/runtime.js:62:40) at GeneratorFunctionPrototype.invoke [as _invoke] (/usr/local/lib/node_modules/web-ext/node_modules/regenerator-runtime/runtime.js:296:22) at GeneratorFunctionPrototype.prototype.(anonymous function) [as next] (/usr/local/lib/node_modules/web-ext/node_modules/regenerator-runtime/runtime.js:114:21) at step (/usr/local/lib/node_modules/web-ext/dist/webpack:/node_modules/babel-runtime/helpers/asyncToGenerator.js:17:1) at /usr/local/lib/node_modules/web-ext/dist/webpack:/node_modules/babel-runtime/helpers/asyncToGenerator.js:35:1 at new Promise (/usr/local/lib/node_modules/web-ext/dist/webpack:/node_modules/core-js/library/modules/es6.promise.js:177:1) at /usr/local/lib/node_modules/web-ext/dist/webpack:/node_modules/babel-runtime/helpers/asyncToGenerator.js:14:1 at fileExists (/usr/local/lib/node_modules/web-ext/dist/web-ext.js:13002:17)

至少更新到最新的 node.v6。我建议你使用 >= v8，因为对 v6 的支持将在 2019 年结束，你不能使用 async/await 例如。 (https://github.com/nodejs/Release#release-schedule)
