三、安装中的错误

1、error: MSGFMT po/de.msg make[1]: *** [po/de.msg] Error 127

解决：yum install tk zlib-devel openssl-devel perl cpio expat-devel gettext-devel

2、errro: asciidoc: command not found

解决：yum install -y asciidoc

3、errro:xmlto: command not found

解决：yum install -y xmlto

最后提醒，升级安装git的时候，最好一次安装依赖。

yum install -y tk zlib-devel openssl-devel perl cpio expat-devel gettext-devel asciidoc xmlto

这里执行make all doc时还会报一个错误

usr/bin/perl Makefile.PL PREFIX='/usr/local/git' INSTALL_BASE='' --localedir='/usr/local/git/share/locale'

Can't locate ExtUtils/MakeMaker.pm in @INC (@INC contains: /usr/local/lib64/perl5 /usr/local/share/perl5 /usr/lib64/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib64/perl5 /usr/share/perl5 .) at Makefile.PL line 3.

BEGIN failed--compilation aborted at Makefile.PL line 3.

make[1]: *** [perl.mak] Error 2

make: *** [perl/perl.mak] Error 2

解决方法：

yum install perl-ExtUtils-MakeMaker package
