错误jemalloc/jemalloc.h:生成Redis时没有这样的文件或目录

Question

我正在尝试设置我的Redis服务器，当执行make命令时，得到错误："jemalloc/jemalloc.h:当创建Redis时没有这样的文件或目录“，我已经尝试了我能找到的所有步骤，例如make distclean或make MALLOC=libc。我在CentOS上工作，它在我的另一台Ubuntu服务器上工作。

系统信息: Linux ec4t02229 3.10.0-514.10.2.el7.x86_64 #1 SMP Fri Mar 3 00:04:05 UTC 2017 x86_64 GNU/Linux

以下是我的输出，任何建议都将不胜感激。

在构建Redis时，通过设置MALLOC环境变量来选择非默认内存分配器。默认情况下，Redis是针对libc malloc进行编译和链接的，但jemalloc是Linux系统上的默认设置。之所以选择这个默认值，是因为jemalloc已经证明比libc malloc有更少的碎片问题。3.

要针对libc malloc强制编译，请使用：

% make MALLOC=libc：

要在Mac OS X系统上针对jemalloc进行编译，请使用：

% make MALLOC=jemalloc

在redis-6.2.0上进行构建时，我也遇到了同样的错误。

通过执行make distclean，我就摆脱了这个错误

[manjunath@beta-test redis-6.2.0]$ make distclean
