启动 watchman 时出错

Question

嗨，当我想使用“react-native start”启动我的应用程序时，我收到了这个错误。有人知道该怎么做吗？我试图将watchman文件夹和项目文件夹的权限更改为chmod -R 777 'path'

Metro Bundler ready.

您是否尝试过从源代码的根目录运行此脚本 - 通常可以解决我的守望问题：

React Native Clean

你可以从你的package.json所在的目录运行如下：

# Download
wget https://gist.githubusercontent.com/jesussteve/45a9251e4d1419283086379e069aed56/raw/fb0107399b684dad3fecbc1af478575bfe0cb65f/react-native-clean.sh

# Set permissions
chmod a+x react-native-clean.sh

# Run script from current path
./react-native-clean.sh ./

建议运行前先备份，以防万一。
