宝塔面板安装php失败：提示No package ‘libjpeg’ found的解决办法

现象：

升级php7.4的时候，报错如下：
No package 'libjpeg' found

Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.

Alternatively, you may set the environment variables JPEG_CFLAGS
and JPEG_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.
make: *** No targets specified and no makefile found.  Stop.
make: *** No rule to make target `install'.  Stop.

解决办法：

yum install -y libjpeg libjpeg-devel
