无法使用easy_install安装Python模块

Question

我正在尝试使用easy_install通过执行安装名为请求的模块

easy_install requests

一周前，当我使用Python 2.6.5时，此方法运行良好，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，但收到此错误

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.

因此，我被告知要重新安装easy_install，然后我去了http://pypi.python.org/pypi/setuptools ，得知我必须

首先从系统的site-packages目录（和任何其他sys.path目录）中删除所有setuptools * .egg和setuptools.pth文件。

所以我做到了。 然后，我从setuptools-0.6c11-py2.7.egg重新安装了setuptools-0.6c11-py2.7.egg 。 似乎成功了，但是当我运行easy_install requests时，除了目录python2.6 / dist-packages现在是python2.7 / site-packages外，我基本上遇到了相同的错误

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
the distutils default setting) was:

    /usr/local/lib/python2.7/site-packages/

另外，当我执行easy_install并按tab时，我会获得以下选项

easy_install      easy_install-2.6  easy_install-2.7

easy_install-2.6为何出现？

和

如何使易安装的产品再次工作？

Answer 1

您是否尝试过像这样使用sudo ？

sudo easy_install requests

或将安装目录指定为您具有写特权的目录。

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

但是您应该真正使用PIP而不是easy_install 。 它要好得多，并具有更多功能。

Answer 2

您应该在基于软件包的Linux发行版上使用virtualenv ，这样Python脚本就不会干扰其他软件包或与操作系统的软件包管理器冲突。

Answer 3

以下对我有用的Ubuntu 12.10安装easy_install然后pip ：

sudo apt-get install python-virtualenv
curl -O https://raw.github.com/pypa/pip/master/contrib/get-pip.py
sudo python get-pip.py

Answer 4

您是否尝试过将新的python.framework添加到path？ 在山狮上，我将/Library/Frameworks/Python.framework/Versions/3.3/bin/添加到/etc/paths ，然后可以使用easy_install-3.3和pip-3.3

Answer 5

在easy_install之前使用Sudo可能会解决您的问题

Sudo easy_install requests

谢谢

Answer 6

这可能是您在前面缺少“ sudo”的简单情况。 您可以使用sudo简易安装请求尝试吗

放置“ sudo”将添加所需的权限。
