PHP安装问题集锦

环境：

Ubuntu-16.4

PHP-7.1.7

安装前准备：

$ sudo apt update $ sudo apt upgrade

error: xml2-config not found. Please check your libxml2 installation.

$ sudo apt install libxml2-dev

error: Cannot find OpenSSL's <evp.h>

ps:一开始安装的openssl，但还是报这错，后来安装libssl-dev，问题解决。所以不知道是要两个一起安装，还是只安装libssl-dev就行。

$ sudo apt install openssl libssl-dev

error: Please reinstall the libcurl distribution - easy.h should be in <curl-dir>/include/curl/

$ sudo apt install libcurl4-openssl-dev

error: jpeglib.h not found.

$ sudo apt install libjpeg-dev

error: png.h not found.

$ sudo apt install libpng-dev

error: freetype-config not found.

$ sudo apt install libfreetype6-dev

error: mcrypt.h not found. Please reinstall libmcrypt.

$ sudo apt install libmcrypt-dev

error: xslt-config not found. Please reinstall the libxslt >= 1.1.0 distribution

$ sudo apt install libxslt-dev
