RVM 安装失败，错误："__rvm_detect_max_threads:cd:21: string not in pwd: /***"

Question

我刚刚升级了macOs到Sierra，并试图设置它。在尝试使用rvm安装ruby时，我得到了这个非常奇怪的错误:

__rvm_detect_max_threads:cd:21: string not in pwd: /Users/sunday/workspace/contributions

我在目录/workspace/contributions中只有一个文件夹，不知道错误是什么，试图删除/workspace/contributions，但错误仍然存在。

在使用--debug选项时，以下是我的跟踪:

当我尝试使用install而不是reinstall时，也会发生这种情况。

这里可能会发生什么，我如何解决这个问题以便在我的机器上安装ruby ?

Answer 1

 ➜  ~ ruby -v
 ruby 2.0.0p648 (2015-12-16 revision 53162) [universal.x86_64-darwin16]

删除这个darwin版本的ruby，它是osx的默认版本。

卸载区

rvm implode

按照文档安装rvm

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

重启终端，确认rvm安装正确。

rvm notes

使用rvm不安装ruby版本

rvm install 2.2.0

Answer 2

在Github上遵循这个线程https://github.com/rvm/rvm/issues/3686，我能够通过使用命令来安装它:

rvm install ruby-2.3.1 --disable-binary -j 8

根据注释:

因此，看起来"检测CPU线程数"的功能，无论出于何种原因，在我的机器上破坏了它。
