返回找不到匹配项:python3

没有一个搜索结果包含 python3.接下来我应该尝试什么?

推荐答案

手动安装很容易:

1. 下载(Python.org 上可能有更新的版本):

1. Download (there may be newer releases on Python.org):

$ wget https://www.python.org/ftp/python/3.4.3/Python-3.4.3.tar.xz

解压

Unzip

$ tar xf Python-3.* 
$ cd Python-3.*

准备编译

Prepare compilation

$ ./configure

构建

Build

$ make

安装

Install

$ make install

或者，如果您不想覆盖 python 可执行文件(更安全，至少在某些发行版上 yum 需要 python 为 2.x，例如 RHEL6) - 您可以使用 altinstall 将 python3.* 作为并发实例安装到系统默认:

OR if you don't want to overwrite the python executable (safer, at least on some distros yum needs python to be 2.x, such as for RHEL6) - you can install python3.* as a concurrent instance to the system default with an altinstall:

$ make altinstall

现在如果你想要一个替代的安装目录，你可以将 --prefix 传递给 configure 命令.

Now if you want an alternative installation directory, you can pass --prefix to the configurecommand.

示例:要在/opt/local 中安装"Python，只需添加 --prefix=/opt/local.

Example: for 'installing' Python in /opt/local, just add --prefix=/opt/local.

在 make install 步骤之后:为了使用新的 Python 安装，您可能仍然需要将 [prefix]/bin 添加到 $PATH 和 [prefix]/lib 到 $LD_LIBRARY_PATH(取决于您传递的 --prefix)

After the make install step: In order to use your new Python installation, it could be, that you still have to add the [prefix]/bin to the $PATH and [prefix]/lib to the $LD_LIBRARY_PATH (depending of the --prefix you passed)
