当我想在Android模拟器上运行我的项目时，我收到此错误。

我试过“守望者手表〜路径”，“sudo”＆amp; “chmod”，但他们没有帮助我。

有人可以告诉我吗？

Answer 1

cd AwesomeProject，并执行chmod -R 777 *它仍然失败。在我允许顶级目录之后，它起作用了！ chmod 777 AwesomeProject

Answer 2

通过重新安装守望者来解决

brew update
brew reinstall watchman

Answer 3

检查pid并杀死

lsof -n -i4TCP:8081 | grep LISTEN

使用root

运行此命令

react-native start

Answer 4

我已经尝试了以上所有方法，并且没有一个解决方案有效，请尝试：

输入watchman watch ./

在您要运行的RN项目的顶级目录中，

然后再次react-native run-ios

Answer 5

检查pid

PM> add-migration <name>
PM> update-database

并杀死pid

以root身份运行

lsof -n -i4TCP:8081 | grep LISTEN

React-Native无法构建DependencyGraph：Watchman错误
