無法使用easy_install安裝Python模塊

Question

我正在嘗試使用easy_install通過執行安裝名為請求的模塊

easy_install requests

一周前，當我使用Python 2.6.5時，此方法運行良好，但今天，我安裝了Python 2.7.2，然后嘗試在我的一個腳本中import requests ，但失敗了。 然后，我嘗試使用easy_install requests重新安裝請求，但收到此錯誤

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

首先從系統的site-packages目錄（和任何其他sys.path目錄）中刪除所有setuptools * .egg和setuptools.pth文件。

所以我做到了。 然后，我從setuptools-0.6c11-py2.7.egg重新安裝了setuptools-0.6c11-py2.7.egg 。 似乎成功了，但是當我運行easy_install requests時，除了目錄python2.6 / dist-packages現在是python2.7 / site-packages外，我基本上遇到了相同的錯誤

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，當我執行easy_install並按tab時，我會獲得以下選項

easy_install      easy_install-2.6  easy_install-2.7

easy_install-2.6為何出現？

和

如何使易安裝的產品再次工作？

Answer 1

您是否嘗試過像這樣使用sudo ？

sudo easy_install requests

或將安裝目錄指定為您具有寫特權的目錄。

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

但是您應該真正使用PIP而不是easy_install 。 它要好得多，並具有更多功能。

Answer 2

您應該在基於軟件包的Linux發行版上使用virtualenv ，這樣Python腳本就不會干擾其他軟件包或與操作系統的軟件包管理器沖突。

Answer 3

以下對我有用的Ubuntu 12.10安裝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

您是否嘗試過將新的python.framework添加到path？ 在山獅上，我將/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可能會解決您的問題

Sudo easy_install requests

謝謝

Answer 6

這可能是您在前面缺少“ sudo”的簡單情況。 您可以使用sudo簡易安裝請求嘗試嗎

放置“ sudo”將添加所需的權限。
