我在 ubuntu 12.04.5 LTS 上并尝试使用 jemalloc 安装 ruby​​。jemalloc 安装成功（https://blog.scalingo.com/2017/05/02/improve-ruby-application-memory-jemalloc.html）但是在安装 ruby​​ 2.3.4 时，它给出了以下错误。

>rvm install 2.3.4 -C --with-jemalloc

Warning, new version of rvm available '1.29.1', you are using older version '1.27.0'.
You can disable this warning with:    echo rvm_autoupdate_flag=0 >> ~/.rvmrc

在 [xK]ubuntu 18.10 上

我做了

sudo apt install libjemalloc-dev
rvm install 2.5.2 -C --with-jemalloc
rvm use 2.5.2
ruby -r rbconfig -e "puts RbConfig::CONFIG['LIBS']"

我使用 Ubuntu 18.04。像这样更改命令

RUBY_EXTRA_CONFIGURE_OPTIONS="--with-jemalloc" rvm install 2.3.4 --disable-binary

要检查 jemalloc 是否已安装，请运行以下命令：

ruby -r rbconfig -e "puts RbConfig::CONFIG['LIBS']"

如果安装 rvm 后无法识别 ruby​​。

source ~/.rvm/scripts/rvm

当调用 jemalloc 时。你可以看到响应。

-lpthread -ljemalloc -ldl -lobjc

您可以在此处查看完整文档

在尝试让 rails 使用 jemalloc 时，我遇到了这个问题的一个变体。在我的情况下，我（有目的地）安装了系统范围的红宝石，rvm但忘记rvmsudo像这样使用：

$ sudo apt update; sudo apt install libjemalloc-dev -y
$ rvmsudo rvm reinstall 2.4.1 -C --with-jemalloc

如果您在尝试让 jemalloc 在类似情况下工作时收到权限警告，请试一试^^^...
