安装RVM时运行'make -j2'时出错 [英] Error running 'make -j2' when installing RVM

问题描述

我正在按照本教程在Mac上设置Rails:

I'm following this tutorial on setting up Rails on your Mac :

http://www.moncefbelyamani.com/how-to-install-xcode-homebrew-git-rvm-ruby-on-mac/

当我进入第6步:使用Ruby 1.9.3安装RVM 并运行curl -L https://get.rvm.io | bash -s stable --ruby来安装RVM时，出现以下错误:

When I get to Step 6: Install RVM with Ruby 1.9.3, and run curl -L https://get.rvm.io | bash -s stable --ruby to install RVM, I get the following error :

Error running 'make -j2', please read ~/.rvm/log/ruby-1.9.3-p385/make.log
There has been an error while running make. Halting the installation.

在make.log中，它是生成的:

In make.log, here is what it generated :

regparse.c:582:15: error: implicit conversion loses integer precision: 'st_index_t' (aka 'unsigned long') to 'int' [-Werror,-Wshorten-64-to-32]
    return t->num_entries;
    ~~~~~~ ~~~^~~~~~~~~~~
1 error generated.
make: *** [regparse.o] Error 1
make: *** Waiting for unfinished jobs....

我发现这很有趣，因为我之前在类似的设置中遵循了本指南，并且没有遇到任何问题.

I find this strage as I've followed this guide before on a similar setup and didn't encounter any problems.

有什么想法吗?

推荐答案

当您使用clang => 除非您有兴趣测试Ruby/clang的兼容性，否则最好使用gcc-4.2编译ruby(请参阅 https://bugs.ruby-lang.org/issues/5883 了解详情)

Unless you are interested in testing Ruby/clang compatibility you would be better with compiling ruby using gcc-4.2 (see https://bugs.ruby-lang.org/issues/5883 for details)

跳过安装程序中的--ruby标志:

Skip the --ruby flag from the installer:

\curl -L https://get.rvm.io | bash -s stable

RVM具有使用自制软件安装所有必需软件包的命令:

RVM has a command to install all required packages using homebrew:

rvm requirements run force

如果没有自制软件，它将显示所需软件包的列表.

In case homebrew is not available it will display the list of required packages.

替代，有一个补丁可以使其与clang一起使用，请使用以下命令安装ruby:

Alternative there is a patch that could make it working with clang, install ruby using:

rvm install 1.9.3-p385 --patch https://bugs.ruby-lang.org/attachments/download/3496/disable-werror.patch -C --disable-werror
