nginx报错:./configure: error: C compiler cc is not found, gcc 是已经安装了的

源码安装nginx报错，找不到gcc,但是实际上gcc是存在的，如下:

# ./configure 
checking for OS
 + Linux 3.10.0-957.el7.x86_64 x86_64
checking for C compiler ... not found

./configure: error: C compiler cc is not found

# 

尝试找寻gcc

# whereis gcc
gcc: /usr/bin/gcc /usr/lib/gcc /usr/libexec/gcc /usr/share/man/man1/gcc.1.gz
# 

尝试指定cc

# ./configure --with-cc=/usr/bin/gcc
checking for OS
 + Linux 3.10.0-957.el7.x86_64 x86_64
checking for C compiler ... not found

./configure: error: C compiler /usr/bin/gcc is not found

[root@localhost nginx-1.14.2]# ls -l /usr/bin/gcc
-rwxr-xr-x. 2 root root 0 Mar 14 06:44 /usr/bin/gcc# 

依旧报错

最后卸载gcc重新安装成功，不过，模拟不出这种环境了

# yum remove gcc -y
# yum install gcc -y
