不能启动守望者退回到NodeWatcher进行文件系统事件 [英] Could not start watchman; falling back to NodeWatcher for file system events

问题描述

我在我的Ember应用程序之间切换时收到以下错误消息：
version：2.4.2
无法启动watchman;退回到NodeWatcher进行文件系统事件。
访问ember-cli.com了解更多信息。
http：// localhost：49153 上的Livereload服务器
无法在 http：// localhost：4200 。它正在使用或您没有权限。

I get the below error message while I switch between my ember applications: version: 2.4.2 Could not start watchman; falling back to NodeWatcher for file system events. Visit ember-cli.com for more info. Livereload server on http://localhost:49153 Could not serve on http://localhost:4200. It is either in use or you do not have permission.

以下是我在我的机器上设置的软件包：
npm --version
2.14.20
bower --version
1.7.7
ember --version
2.4.2
节点：4.4.0
os：linux x64

Here are the packages that I have setup on my machine: npm --version 2.14.20 bower --version 1.7.7 ember --version 2.4.2 node: 4.4.0 os: linux x64

推荐答案

Ember-cli（从版本0.1.3开始）需要看门人或其他一些服务（例如NodeWatcher）进行文件监视

Ember-cli (starting from release 0.1.3) requires watchman or some other service (e.g. NodeWatcher) for file watching.

您可以在ember-cli版本中找到此信息0.1.3 changelog：
https://github.com/ember-cli/ember-cli/releases/tag/v0.1.3

You can find this info in the ember-cli release 0.1.3 changelog: https://github.com/ember-cli/ember-cli/releases/tag/v0.1.3

尽管我相信你可以使用没有看门人的Ember应用程序，可以确认你已经安装了看门人吗？

Although I believe you could use your Ember app without watchman, could you confirm that you already have watchman installed?

如果没有，这是在Ubuntu 64bit中对我有用的功能：

If not, here's what works fine for me in Ubuntu 64bit:

// installing watchman from source
git clone https://github.com/facebook/watchman.git
cd watchman
./autogen.sh
./configure
make
sudo make install

如果安装后仍然有问题，请同时重置您的看门人配置：

if you still have problems after installing try also resetting your watchman configuration:

watchman watch-del-all
watchman watch-del /home/myproject  // your project folder goes here...
watchman watch-project /home/myproject // your project folder goes
