Question

众所周知，Metacello的第一个或主要目标是Pharo，但现在看来Squeak 4 is supported。我已经尝试但由于缺少方法而失败。从成绩单：

我正在使用Squeak 4.4-12327图片。对此有何帮助？

Answer 1

我刚刚在4.4中运行了这个（由Github上的安装文档提出）并且没有任何问题：

Installer gemsource
project: 'metacello';
install: 'ConfigurationOfMetacello'. 

((Smalltalk at: #ConfigurationOfMetacello) project 
  version: '1.0-beta.32') load.

您使用的代码是什么？

Answer 2

以上解决方案不再有效

你需要使用下面的代码来获取它

(Installer monticello http:'http://seaside.gemtalksystems.com/ss')
project: 'metacello';
install: 'ConfigurationOfMetacello'. 

((Smalltalk at: #ConfigurationOfMetacello) project 
  latestVersion) load.

Answer 3

FWIW，从Squeak 5.3（可能更早）开始，现在Metacello安装已集成到Squeak中。

要通过UI加载Metacello，请打开主停靠栏中的“应用程序”菜单，然后选择“首选项向导”。按“完成”，然后在下一个视图中选择要安装的Metacello。

要从代码加载Metacello，请在任何工作空间/ CodeHolder中评估Metacello new或Installer ensureRecentMetacello。

如何在Squeak中加载Metacello？
