python - 无法使用 easy_install 安装 Python 模块

Question

我正在尝试使用 easy_install 安装一个名为 requests 的模块

easy_install requests

一周前，当我使用 Python 2.6.5 时，它运行良好，但今天我安装了 Python 2.7.2，然后尝试在我的一个脚本中import requests，但失败了。然后我尝试使用 easy_install requests 重新安装请求，但出现此错误

install_dir /usr/local/lib/python2.6/dist-packages/
error: can't create or remove files in install directory

The following error occurred while trying to add or remove files in the
installation directory:

    [Errno 13] Permission denied: '/usr/local/lib/python2.6/dist-packages/test-easy-install-15207.pth'

The installation directory you specified (via --install-dir, --prefix, or
the distutils default setting) was:

    /usr/local/lib/python2.6/dist-packages/

Perhaps your account does not have write access to this directory?  If the
installation directory is a system-owned directory, you may need to sign in
as the administrator or "root" account.  If you do not have administrative
access to this machine, you may wish to choose a different installation
directory, preferably one that is listed in your PYTHONPATH environment
variable.

For information on other options, you may wish to consult the
documentation at:

  http://packages.python.org/distribute/easy_install.html

Please make the appropriate changes for your system and try again.

所以我被告知去重新安装 easy_install 然后我去了 http://pypi.python.org/pypi/setuptools并了解到我必须

delete all setuptools*.egg and setuptools.pth files from your system's site-packages directory (and any other sys.path directories) FIRST.

所以我这样做了。然后我从 setuptools-0.6c11-py2.7.egg 重新安装了 setuptools。它似乎成功了，但是当我运行 easy_install requests 时，我得到了基本相同的错误，除了目录 python2.6/dist-packages 现在是 python2.7/site-packages

siddhion@siddhion-laptop:~$ easy_install requests
error: can't create or remove files in install directory

The following error occurred while trying to add or remove files in the
installation directory:

    [Errno 13] Permission denied: '/usr/local/lib/python2.7/site-packages/test-easy-install-16253.write-test'

The installation directory you specified (via --install-dir, --prefix, or

此外，当我执行 easy_install 并按 Tab 键时，我会得到这些选项

easy_install      easy_install-2.6  easy_install-2.7

easy_install-2.6 是怎么来的？

和

我如何让简易安装再次工作？

Answer 1

你试过像这样使用 sudo 吗？

sudo easy_install requests

或者将安装目录指定为您具有写入权限的目录。

easy_install --install-dir=/home/foo/bar

但你真的应该使用PIP而不是 easy_install。它要好得多，并且具有更多功能。
