如何卸载或升级Erlang / OTP？ [英] How to uninstall or upgrade Erlang/OTP?

问题描述

如何卸载 Erlang / OTP ，我使用 make install 从源代码创建。使用 ./ configure; make; make install;

How can I uninstall Erlang/OTP which I use make install to build from source earlier. The install is pretty simple by using ./configure;make;make install;

卸载的原因是我想从 Erlang R15B01 升级到 Erlang R15B03 。

The reason to uninstall is that I want to upgrade from Erlang R15B01 to Erlang R15B03.

现在我有：

# erl --version
Erlang R15B01 (erts-5.9.1) [source] [64-bit] [smp:2:2] [async-threads:0] [hipe] [kernel-poll:false]

Eshell V5.9.1  (abort with ^G)

推荐答案

有一个选项--prefix =脚本路径configure，其中path是要安装应用程序的目录的路径。例如：

There is an option --prefix=path of script configure, where path is a path to directory where you want to install an application. For instance:

./configure --prefix=/opt/erlang-R15B01

不要忘记为PATH环境变量添加适当的路径。

Do not forget to add appropriate path to PATH environment variable.

在以前的安装过程中，请使用此选项，然后使用默认路径（/ usr或/ usr / local），您可以按照相同的方式安装旧版本的旧版本 -

If you didn't use this option during previous installation then the default path was used (/usr or /usr/local) and you can just install new version above old one the same way -

./configure && make && make install.
