将安装安装到自定义目标目录，并排除特定的依赖项 [英] Pip install to custom target directory and exclude specific dependencies
问题描述
我正在寻找一种使用pip或类似方法将python软件包列表安装到自定义目标目录(例如/mypath/python/pkgs/)的方法，但还要排除/黑名单特定依赖性.
I'm looking for a method to use pip or similiar to install a list of python packages to a custom target directory (ex./mypath/python/pkgs/ ), but also exclude/blacklist specific dependencies.
我想排除特定的依赖关系，因为它们已经通过不同的安装路径得到了满足(例如anaconda安装).我没有特权将软件包添加到默认的python安装中(我也不想要).
I want to exclude specific dependencies since they are already met from a different install path (e.g. an anaconda install). I don't have the privilege of adding packages to the default python installation (nor do I want to).
我目前正在使用pip的-r和-t选项.但尚未找到排除特定程序包的方法.
I'm currently use the -r and -t options of pip. But have not found a way to exclude specific packages.
像这样的pip命令将是理想的:
A pip command like this is would be ideal:
pip install --log pip.log -r req.txt -t /mypath/pypkgs/ --exclude exclude.txt
--no-deps不是一个选项，因为我需要一些依赖项.
--no-deps is not an option since I need some of the dependencies.
我目前正在使用python脚本进行pip安装，这些安装包括不需要的依赖项，通过以下方式进行操作:
I'm currently pursuing a python script to do pip installs that include dependencies I don't need via:
pip install --log pip.log -r req.txt -t /mypath/python/pkgs/
，然后在pip安装完成后(自动)删除不需要的依赖项.
and then (automatically) remove the unneeded dependencies after the pip install finishes.
我希望pip命令的某种组合可以实现我正在寻找的一些简单方法.我正在使用7.1.2点.谢谢！
I hoping some combination of pip commands can achieve what I'm looking for some straightforward away. I'm using pip 7.1.2. Thanks!
类似，但我没有升级，但想指定目标路径:
Similar, yet I'm not upgrading and want to specify a target path:
推荐答案
遇到类似的问题，并且使用运行中的bash shell，我设法用
Faced with a similar problem, and using a running bash shell I managed to exclude specific packages with
pip install $(grep -ivE "pkg1|pkg2|pkg3" requirements.txt)
其中pkg1等是要排除的软件包的名称.
where pkg1 and so on are the names of the packages to exclude.
