使用jemalloc安装ruby时出错
使用jemalloc安装ruby时出错
提问于 2017-05-11 15:15:15
我在ubuntu 12.04.5LTS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Ruby2.3.4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
You can enable auto-update with: echo rvm_autoupdate_flag=2 >> ~/.rvmrc

There has been an error while running make. Halting the installation.有没有人曾经遇到过或者可能有过这样的经历，请帮助。

我做到了

我使用Ubuntu 18.04。如下所示更改命令
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']"如果在安装rvm后无法识别ruby。
source ~/.rvm/scripts/rvm当jemalloc被调用时。您可以看到响应。
-lpthread -ljemalloc -ldl -lobjc您可以查看完整的文档here

当我试图让rails使用jemalloc时，我遇到了这个问题的一个变体。在我的例子中，我已经(故意)通过rvm安装了系统范围内的rvmsudo，但是忘记了像这样使用rubies：
$ sudo apt update; sudo apt install libjemalloc-dev -y
$ rvmsudo rvm reinstall 2.4.1 -C --with-jemalloc如果您在类似的场景中尝试让jemalloc工作时收到权限警告，请尝试^...
