看到一個(gè)基于swoole的聊天室,php 環(huán)境根據(jù)yum安裝lnmp安裝好了，之后安裝swoole,但是失敗了 [root@VM_0_14_centos html]# cat /etc/redhat-release CentOS Linux release 7.2.1511 (Core) [root@VM_0_14_centos html]# pecl install swoole Could not download from "http://pecl.php.net/get/swoole-4.2.7.tgz", cannot download "pecl/swoole" (File http://pecl.php.net:80/get/swoole-4.2.7.tgz not valid (received: HTTP/1.0 500 Internal Server Error )) Error: cannot download "pecl/swoole" Download failed install failed 于是開(kāi)始源碼安裝 #git clone https://github.com/swoole/swoole-src #cd swoole-src #phpize #./configure checking for gcc... no checking for cc... no checking for cl.exe... no configure.sh:error:no acceptable C compiler found in $PATH See 'config.log' for more details. 更新： 后來(lái)重新安裝成功了 #yum -y install gcc #./configure checking how to run the C++ preprocessor... /lib/cpp configure: error: C++ preprocessor "/lib/cpp" fails sanity check See `config.log' for more details. #yum install glibc-headers gcc-c++ #./configure Build complete.
