我在Ubuntu 15.10上,我正在使用react-native(0.20.0)开发
Android(SDK 23)应用程序.我正在使用节点5.6.0和npm 3.6.0.
我在运行react-native start时遇到了一个watchman错误
ERROR watchman--no-pretty get-sockname returned with exit code 127 watchman:
error while loading shared libraries: libpcre.so.1: cannot open shared object
file: No such file or directory
at ChildProcess.<anonymous> (/home/rachael/Dev/InstaGo/node_modules/fb-watchman/index.js:198:18)

当我运行sudo find / -name libpcre.so.1时,返回以下内容:
/home/rachael/.linuxbrew/lib/libpcre.so.1
/home/rachael/.linuxbrew/Cellar/pcre/8.38/lib/libpcre.so.1
我试过重新安装守望者:
make uninstall
git clone https://github.com/facebook/watchman.git
cd watchman
git checkout v4.1.0 # the latest stable release .
/autogen.sh
./configure
make
sudo make install
我也用linuxbrew尝试过:
npm r -g watchman
brew update && brew upgrade
brew install watchman
这给出了一个完全不同的错误:
A non-recoverable condition has triggered. Watchman needs your help!
The triggering condition was at timestamp=1407695600: inotify-add-watch(/my/path) -> Cannot allocate memory
All requests will continue to fail with this message until you resolve
the underlying problem. You will find more information on fixing this at

Facebook的故障排除页面非常模糊,我无法解决该错误.
我对此很新,所以我很感激这个问题的任何帮助.感谢您的时间.
更新
通过linuxbrew安装watchman.
使用linuxbrew时,请记住在安装任何公式之前包含以下命令:
export PATH="$HOME/.linuxbrew/bin:$PATH"
export MANPATH="$HOME/.linuxbrew/share/man:$MANPATH"
export INFOPATH="$HOME/.linuxbrew/share/info:$INFOPATH"
brew update && brew upgrade
然后安装最新版本的watchman:
brew install --HEAD watchman
然后增加inotify用户实例,用户监视和排队事件的数量:
echo fs.inotify.max_user_instances=524288 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p
echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p
echo fs.inotify.max_queued_events=524288 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p
现在守望者应该工作和反应 – 本地开始应该运行良好!
最佳答案 您发布的第一个问题是与ldconfig相关的问题;由于pcre二进制文件未安装在系统库路径中,因此运行时链接程序无法在运行时解析它们,因此无法启动watchman二进制文件.
我无法帮助您直接解决问题的这一部分,但这听起来就像您尝试的后续步骤让您处于更好的位置.
请注意,当前发布的守望者版本是4.5.0;您所关注的路线已过时(您能否告诉我您在哪里找到这些路线?)
https://facebook.github.io/watchman/docs/install.html始终拥有当前信息.
现在,到毒药问题:
您看到的错误消息中包含一个(损坏,抱歉!)链接到https://facebook.github.io/watchman/docs/troubleshooting.html#poison-inotify_add_watch,其中包含对正在发生的事情的一些解释.
您需要阅读本节有关正确设置系统限制的内容:
https://facebook.github.io/watchman/docs/install.html#system-specific-preparation
完成后,您可以通过运行watchman shutdown-server来清除状态
这有帮助吗?我想知道你发现哪些部分含糊不清,以便我可以为其他人改进它!
