使用jemalloc安装ruby时出错

Question

我在ubuntu 12.04.5 LTS上尝试用jemalloc安装ruby.jemalloc已成功安装(https://blog.scalingo.com/2017/05/02/improve-ruby-application-memory-jemalloc.html),但在安装ruby 2.3.4时,它出现了以下错误.

>rvm install 2.3.4 -C --with-jemalloc

You can disable this warning with:    echo rvm_autoupdate_flag=0 >> ~/.rvmrc

有没有人遇到它或者可能有它的经验,请帮忙.

Answer 1

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']"

Answer 2

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rvm安装后无法识别ruby。

source ~/.rvm/scripts/rvm

当 jemalloc 被调用时。你可以看到回复。

-lpthread -ljemalloc -ldl -lobjc
