Stop pip from failing on single package when installing with requirements.txt
I am installing packages from requirements.txt
pip install -r requirements.txt
The requirements.txt file reads:
Pillow lxml cssselect jieba beautifulsoup nltk
lxml is the only package failing to install and this leads to everything failing (expected results as pointed out by larsks in the comments). However, after
pip still runs through and downloads the rest of the packages.
From what I understand the
pip install -r requirements.txt command will fail if any of the packages listed in the
requirements.txt fail to install.
Is there any argument I can pass when running
pip install -r requirements.txt to tell it to install what it can and skip the packages that it cannot, or to exit as soon as it sees something fail?
Running each line with
pip install may be a workaround.
cat requirements.txt | xargs -n 1 pip install
-a parameter is not available under MacOS, so old cat is more portable.
