Unable to install using pip install requirements.txt
提问by Avdhesh Parashar
I'm trying to install BitTornadofor Python 2.7 using requirements.txt, I get the following error:
我正在尝试使用 requirements.txt 为 Python 2.7安装BitTornado，但出现以下错误：
Collecting requirements.txt
Could not find a version that satisfies the requirement requirements.txt (from versions: )
No matching distribution found for requirements.txt
Here is my code in requirements.txt:
这是我在requirements.txt中的代码：
-e git+https://github.com/effigies/BitTornado.git#egg=python2.7
I also tried -e git+https://github.com/effigies/[email protected]but still not working. Does someone know why is this happening?
我也试过 -e git+ https://github.com/effigies/[email protected]但仍然无法正常工作。有人知道为什么会这样吗？
Note: "python2.7" is the branch name
注意：“python2.7”是分支名称
Thanks in Advance

The correct command is pip install -r requirements.txt. Note the -roption; without it, pip thinks you want to install a package named requirements.txt, which doesn't exist.
正确的命令是pip install -r requirements.txt. 注意-r选项；没有它，pip 会认为您要安装一个名为 的包requirements.txt，但该包不存在。

You forgot to add -rswitch to specify that requirements.txtis the file with your dependencies.
您忘记添加-r开关以指定requirements.txt具有依赖项的文件。
