当在requirements.txt中提到它们时，如何通过--no-build-isolation安装pip软件包？

Question

上下文： 这是我面临的问题https://github.com/pypa/pip/issues/6717#issue-468204416
并试图通过解决 https://github.com/pypa/pip/issues/6717#issuecomment-511652167

我要使用

--no-build-isolation

在py2.7 venv中，如果我这样做：

pip install bottleneck==1.2.1 --no-build-isolation

Collecting bottleneck==1.2.1
Collecting numpy (from bottleneck==1.2.1)

You are using pip version 18.0, however version 19.2.3 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

安装正常

$ cat abc.txt 
bottleneck==1.2.1, --no-build-isolation

但是

$pip install -r abc.txt
Usage: pip [options]

Invalid requirement: bottleneck==1.2.1, --no-build-isolation
pip: error: no such option: --no-build-isolation

You are using pip version 18.0, however version 19.2.3 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

和

$ pip install -r abc.txt
Usage: pip [options]

Invalid requirement: bottleneck==1.2.1 --no-build-isolation
pip: error: no such option: --no-build-isolation

You are using pip version 18.0, however version 19.2.3 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

不起作用。

我该怎么做。

我也尝试过bottleneck tries to install numpy release candidate，但没有帮助。

将pip升级到pip-20.2.2为我解决了这个难题。 命令

pip install --upgrade pip
