gem install redis

報錯資訊1:

[[email protected]_0_15_centos bin]# gem install redis
ERROR:  Loading command: install (LoadError)
    cannot load such file -- zlib
ERROR:  While executing gem ... (NoMethodError)
    undefined method `invoke_with_build_args' for nil:NilClass

錯誤1解決方案:

cd /ruby-2.3.1原始碼目錄/ext/zlib

執行命令:

ruby ./extconf.rb

make

make install

報錯資訊1.1:

checking for deflateReset() in -lz... no
checking for deflateReset() in -llibz... no
checking for deflateReset() in -lzlib1... no
checking for deflateReset() in -lzlib... no
checking for deflateReset() in -lzdll... no
checking for deflateReset() in -lzlibwapi... no

出現該資訊是缺少依賴導致: 安裝 zlib-devel，重新執行解決方案1的步驟.

--------

報錯資訊2:

[[email protected]_0_15_centos zlib]# gem install redis
ERROR:  While executing gem ... (Gem::Exception)
    Unable to require openssl, install OpenSSL and rebuild ruby (preferred) or use non-HTTPS sources
[[email protected]_0_15_centos zlib]# yum install openssl
Loaded plugins: fastestmirror, langpacks
Loading mirror speeds from cached hostfile
Package 1:openssl-1.0.2k-8.el7.x86_64 already installed and latest version
Nothing to do

錯誤2解決方案:

 cd /ruby-2.3.1原始碼目錄/ext /openssl/

執行命令:

[[email protected]_0_15_centos openssl]# ruby ./extconf.rb

若出現以下資訊:

[[email protected]_0_15_centos openssl]# ruby ./extconf.rb
checking for t_open() in -lnsl... no
checking for socket() in -lsocket... no
checking for assert.h... yes
checking for openssl/ssl.h... no

則是缺少 依賴包 openssl-devel，安裝即可.

繼續執行命令

[[email protected]_0_15_centos openssl]# make

若出現錯誤資訊:

make: *** No rule to make target `/include/ruby.h', needed by `ossl_x509attr.o'.  Stop.

則需要編輯 生成的 Makefile 檔案，開啟該檔案,增加 top_srcdir = ../.. 即可。

[[email protected]_0_15_centos openssl]# make install

[[email protected]_0_15_centos openssl]# gem install redis
