嗨,当我想用​​'react-native start'启动我的应用程序时,我收到此错误.有人知道该怎么办？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.

您是否尝试过从源的根目录运行此脚本 - 通常可以解决我的守望者问题：

反应本机清洁

package.json您可以从存储目录运行如下：

# 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 ./

建议在运行之前先备份以防万一。
