我想用

\n\n

--no-build-isolation\n

\n\n

在 py2.7 venv 中如果我这样做：

\n\n

\n\n

安装得很好

\n\n

$ cat abc.txt \nbottleneck==1.2.1, --no-build-isolation\n

\n\n

但

\n\n

$pip install -r abc.txt\nUsage: pip [options]\n\nInvalid requirement: bottleneck==1.2.1, --no-build-isolation\npip: error: no such option: --no-build-isolation\n\nYou are using pip version 18.0, however version 19.2.3 is available.\nYou should consider upgrading via the \'pip install --upgrade pip\' command.\n\n\n

\n\n

和

\n\n

$ pip install -r abc.txt\nUsage: pip [options]\n\nInvalid requirement: bottleneck==1.2.1 --no-build-isolation\npip: error: no such option: --no-build-isolation\n\nYou are using pip version 18.0, however version 19.2.3 is available.\nYou should consider upgrading via the \'pip install --upgrade pip\' command.\n\n

\n\n

不工作。

\n\n

我该怎么办呢。

\n\n

我还尝试了瓶颈尝试安装 numpy 候选版本，但它没有帮助。
