无法使用easy_install安装Python模块

Question

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

easy_install requests

一周前我使用 Python 2.6.5 时工作正常，但今天我安装了 Python 2.7.2然后尝试在我的一个脚本中导入请求，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.

所以我被告知要重新安装 easy_install，我去了 http://pypi.python.org/pypi/setuptools 并了解到我必须这样做

删除您的所有 setuptools*.egg 和 setuptools.pth 文件 系统的 site-packages 目录（以及任何其他 sys.path 目录） 首先。

所以我就这么做了。然后，我从 setuptools-0.6c11-py2.7.egg 重新安装了 setuptools。它看起来很成功，但是当我运行 easy_install requests 时，我得到了基本上相同的错误，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
the distutils default setting) was:

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

另外，当我执行 easy_install 时 并按 Tab 键我得到这些选项

easy_install      easy_install-2.6  easy_install-2.7

easy_install-2.6 怎么会在那里？

以及

如何让简易安装再次正常工作？

Answer 1

您是否尝试过像这样使用 sudo ？

sudo easy_install requests

或者将安装目录指定为您有写入权限的目录。

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

但您确实应该使用 PIP 而不是 easy_install。它更好并且有更多的功能。

Answer 2

您应该在基于包的 Linux 发行版上使用 virtualenv，这样 Python 脚本就不会干扰其他包或与操作系统的包管理器发生冲突。

Answer 3

以下内容对我来说适用于 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 添加到路径中？
在山狮上我添加了
/Library/Frameworks/Python.framework/Versions/3.3/bin/
到
/etc/paths
然后我就可以使用 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

这可能是一个简单的情况，您在前面缺少“sudo”。您可以尝试使用 sudo easy-install 请求，

输入“sudo”将添加所需的权限。
