安装 Python 时出错 [英] Error Installing Python

问题描述

进行安装

我收到以下错误

/usr/bin/install: 无法创建常规文件/usr/local/bin/python2.6: Permission denied make: *** [altbininstall] Error 1

我不是 root 用户，所以我认为这是权限问题.我确实在 /home/my_username 有自己的子文件夹有没有办法通过给出更具体的命令来完成 python 安装?

I am not the root user so I assume its a permissions issue. I do have my own subfolder at /home/my_username Is there a way to complete the python installation there by giving a more specific command perhaps?

Python 2.4 也已经安装，如何确保我实际使用的是 2.6?

Also Python 2.4 is already installed how do I ensure that I am actually using 2.6?

非常感谢！

推荐答案

configure 脚本允许您指定--prefix=[dest].从用法来看:

The configure script lets you specify --prefix=[dest]. From the usage:

默认情况下，`make install' 会安装所有文件/usr/local/bin、/usr/local/lib 等.您可以指定使用 --prefix 的/usr/local 以外的安装前缀，例如 --prefix=$HOME.

By default, `make install' will install all the files in /usr/local/bin, /usr/local/lib etc. You can specify an installation prefix other than /usr/local using --prefix, for instance --prefix=$HOME.

所以要安装在你的主目录的 py26 下:

So to install under py26 in your home directory:

% ./configure --prefix=$HOME/py26
..
% make install
% $HOME/py26/bin/python

要更永久地使用它，请将 $HOME/bin 添加到 ~/.bashrc 中的 PATH 变量(或其他外壳 rcfile).要验证您使用的是哪个 Python，请执行以下操作:

To use this on a more permanent basis, add $HOME/bin to your PATH variable in your ~/.bashrc (or other shell rcfile). To verify which Python you're using, do this:

% which python
/home/user/py26/bin/python

<小时>

确保您在 --prefix 或对 PATH 的分配中没有拼写错误.例如:

---

Make sure you don't have a typo in the --prefix or the assignment to PATH. For example:

% which python
/usr/bin/python

% ls -1 $HOME/py26/bin/python*
/home/user/py26/bin/python
/home/user/py26/bin/python2.6
/home/user/py26/bin/python2.6-config
/home/user/py26/bin/python-config

% export PATH=$HOME/py26/bin:$PATH
% which python
/home/user/py26/bin/python
