我正在将Django应用程序部署到开发服务器上,当我运行pip install -r requirements.txt时,遇到了这个错误:

Traceback (most recent call last):
  File "/var/www/mydir/virtualenvs/dev/bin/pip", line 5, in <module>
    from pkg_resources import load_entry_point
ImportError: No module named pkg_resources

Pkg_resources似乎与setuptools一起分发。最初我认为这可能不会安装到virtualenv中的Python中,因此我使用以下命令将setuptools 2.6(与Python相同版本)安装到virtualenv中的Python站点包中:

sh setuptools-0.6c11-py2.6.egg --install-dir /var/www/mydir/virtualenvs/dev/lib/python2.6/site-packages

编辑:这只发生在virtualenv内部。如果我在virtualenv之外打开一个控制台,那么pkg_resources是存在的,但我仍然得到相同的错误。

关于为什么pkg_resources不在路径上有任何想法吗?

I have had the same problem when I used easy-install to install pip for python 2.7.14. For me the solution was (might not be the best, but worked for me, and this is probably the simplest) that the folder that contained the easy-install.py also contained a folder pkg_resources, and i have copy-pasted this folder into the same folder where my pip-script.py script was (python27\Scripts). Since then, I found it in the python27\Lib\site-packages\pip-9.0.1-py2.7.egg\pip\_vendor folder as well, it might be a better solution to modify the pip-script.py file to import this.

Yum -y install python-setuptools

我配置Ceph有一个问题执行命令“$ Ceph -deploy new node1” 然后执行命令“$ yum -y install python-setuptools”, 那么问题就解决了。谢谢

当我试图遵循OSX指南时,我偶然发现了这个答案。对我有用的是,在运行python get-pip之后,我还必须easy_install pip。这解决了根本无法运行pip的问题。我确实安装了一堆旧的macport软件。这可能有些矛盾。

在CentOS 6安装包python-setuptools修复了它。

yum install python-setuptools

看起来他们已经离开bitbucket,现在在github (https://github.com/pypa/setuptools)

执行的命令为:

wget https://bootstrap.pypa.io/ez_setup.py -O - | sudo python

我在ubuntu 13.10上试图将rhodecode安装到virtualenv时看到过这个错误。对我来说,解决办法就是逃跑

pip install --upgrade setuptools
pip install --upgrade distribute 

在我运行easy_install rhodecode之前。
