我正在運行這個命令：
sudo pecl install ssh2
它導致以下日誌並退出並出現錯誤：

正如你所看到的，它找不到 libssh2。但是，當我運行命令時：
sudo yum install libssh2
它說它已經安裝了：
Setting up Install Process
Package libssh2-1.4.2-1.el6.x86_64 already installed and latest version
Nothing to do
現在，我假設由於某種原因，pecl 安裝程式找不到 libssh2 安裝。我怎麼才能讓它辨識那條路。有沒有簡單的替代方法可以正確完成它？
答案1
如果您只使用 phpseclib（一個純 PHP SSH 用戶端）來模擬 libssh2，您可能會有更好的運氣：
答案2
我做了yum install libssh2-devel然後sudo pecl install ssh2-0.12就工作了。
