创建第一个项目后,打开xcode运行,terminal报错 Watchman: watchman–no-pretty get-sockname returned with exit code null dyld: Library not loaded: /usr/local/opt/pcre/lib/libpcre.1.dylib 解决方案:终端输入 brew link pcre, 如果报错没有写入权限(Could not symlink lib/libpcre.1.dylib /usr/local/lib is not writable.) 则授权给该文件 sudo chown -R $(whoami) /usr/local/lib
