如何根据本地目录中的requirements.txt文件使用pip安装软件包? [英] How to install packages using pip according to the requirements.txt file from a local directory?

问题描述

这是问题

我有一个require.txt，看起来像:

I have a requirements.txt that looks like:

BeautifulSoup==3.2.0
Django==1.3
Fabric==1.2.0
Jinja2==2.5.5
PyYAML==3.09
Pygments==1.4
SQLAlchemy==0.7.1
South==0.7.3
amqplib==0.6.1
anyjson==0.3
...

我有一个本地存档目录，其中包含所有软件包和其他软件包.

I have a local archive directory containing all the packages + others.

我创建了一个新的virtualenv

I have created a new virtualenv with

bin/virtualenv testing

在激活它后，我尝试根据本地存档目录中的requirements.txt安装软件包.

upon activating it, I tried to install the packages according to requirements.txt from the local archive directory.

source bin/activate
pip install -r /path/to/requirements.txt -f file:///path/to/archive/

我得到一些输出，似乎表明安装正常

I got some output that seems to indicate that the installation is fine

Downloading/unpacking Fabric==1.2.0 (from -r ../testing/requirements.txt (line 3))
  Running setup.py egg_info for package Fabric
    warning: no previously-included files matching '*' found under directory 'docs/_build'
    warning: no files found matching 'fabfile.py'
Downloading/unpacking South==0.7.3 (from -r ../testing/requirements.txt (line 8))
  Running setup.py egg_info for package South
....

但是后来检查发现没有正确安装该软件包.我无法导入软件包，但在virtualenv的site-packages目录中找不到任何软件包.那么出了什么问题?

But later check revealed none of the package is installed properly. I cannot import the package, and none is found in the site-packages directory of my virtualenv. So what went wrong?

推荐答案

这对我有用:

$ pip install -r requirements.txt --no-index --find-links file:///tmp/packages

--no-index-忽略软件包索引(仅查看--find-links URL).

--no-index - Ignore package index (only looking at --find-links URLs instead).

-f, --find-links <URL>-如果是URL或html文件的路径，则解析到存档的链接. 如果这是目录的本地路径或file:// URL，请在目录列表中查找档案.

-f, --find-links <URL> - If a URL or path to an html file, then parse for links to archives. If a local path or file:// URL that's a directory, then look for archives in the directory listing.
