当我试图安装最新版本的compass (https://rubygems.org/gems/compass/versions/1.0.0.alpha.17)时,我得到以下错误。

ERROR:  Error installing compass:

这是怎么回事?如何正确安装最新的指南针?


当前回答

我为你这个问题纠结了大约3个小时。从Compass 1.0开始。Alpha19,需求是RVM版本1.9.3。

有几个未收集的帖子,但对我有用的是以下几点:

Sudo gem卸载sass 须藤宝石卸载罗盘 RVM安装ruby-1.9.3-p448 Sudo gem安装sass—pre Sudo宝石安装指南针-pre

这样就成功了。希望它也适用于你!

其他回答

首先必须从Ruby 2.6升级到3.0(参见https://rvm.io/):)

$ curl -sSL https://get.rvm.io | bash -s stable --ruby
$ source /Usrs/myuser/.rvm/scripts/rvm

然后我必须在本地安装它,否则Mac OSX权限不会让我升级它(见错误:当执行gem…(Errno::EPERM)操作不允许)

$ sudo gem install -n /usr/local/bin compass

我不完全确定首先安装rvm是否有必要,但它对升级ruby是有用的。

你可能需要安装苹果的命令行工具,默认情况下可能没有安装在你的系统上。我得到了同样的错误,但在遵循这里的任何说明之前,我安装了命令行工具(由于一个不相关的问题),当我再次尝试时,指南针安装没有问题。YMMV。

对于macOS 10.14 Mojave,确保您已经通过xcode-select——install安装了命令行工具,并运行以下命令来安装std头文件。

sudo open /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg

现在再试一下你的指令。

在优胜美地,你所要做的就是安装命令行工具。这样就有用了。

即使其他宝石安装好了。你必须运行xcode-select——install来安装gem compass。

祝你好运。
