没有名为pkg_resources的模块

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?

当前回答

我通过这样做修复了virtualenv的错误:

复制pkg_resources.py from

/ Library /蟒蛇/ 2.7 / site-packages / setuptools

/图书馆/ Python / 2.7 /网站/

这可能是一个廉价的变通办法，但对我来说很管用。

如果安装工具不存在，您可以尝试通过输入virtualenv——system-site-packages /DESTINATION DIRECTORY来安装system-site-packages，将最后一部分更改为您想要安装的目录。Pkg_rousources.py将在lib/python2.7/site-packages目录下

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.
