尝试chmod 777 /并不好。为什么要这样做呢？这样的感觉不应该被允许。我尝试卸载watchman并使用此命令重新安装以使反应本机开始工作。

Answer 1

brew uninstall watchman
sudo chown -R `whoami` /usr/local
brew link pcre
brew install watchman

Answer 2

尝试

brew update
brew doctor
brew install watchmen

如果您仍然遇到问题，请尝试访问your_project / node_modules / react-native / packager / react-packager / src / FileWatcher / index.js并增加MAX_WAIT_TIME

Answer 3

修复在OSX上安装high sierra 10.13.2需要重新安装自制程序，因为它需要解决不可写的/usr/local/文件夹

我不得不重新安装自制软件：

卸载：

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall)" 重新安装：

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

Answer 4

对我来说和上面一样：

brew update
brew doctor
brew install watchman

还要确保你在 jest 配置中有这个：

watchPathIgnorePatterns: ['node_modules']

brew安装守望者不工作
