解决方案
问题1的解决方案：
为命令添加–no-bin-links参数
yarn install --no-bin-links
问题2的解决方案：
步骤一：
修改项目根目录下的package.json，将`scripts中的内容修改为以下（删掉原内容粘贴新内容即可）：
"dev": "npm run development", "development": "NODE_ENV=development node_modules/webpack/bin/webpack.js --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js", "watch": "NODE_ENV=development node_modules/webpack/bin/webpack.js --watch --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js", "watch-poll": "npm run watch -- --watch-poll", "hot": "NODE_ENV=development node_modules/webpack-dev-server/bin/webpack-dev-server.js --inline --hot --config=node_modules/laravel-mix/setup/webpack.config.js", "prod": "npm run production", "production": "NODE_ENV=production node_modules/webpack/bin/webpack.js --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js"
如图：
步骤二：
执行命令
npm run watch --watch-poll
此时Laravel Mix即可成功运行。
