[英]fail to install requirements using "pip install -r requirements.txt"
[英]'pip install -r requirements.txt' fails when using Chef
我有一个脚本已复制到Chef节点; 它会激活python虚拟环境,然后从需求文件中安装需求:
#!/bin/bash
source venv/bin/activate
pip install -v -r requirements.txt >> scripts/scripts.out
当我在本地运行时,一切都很好。 当使用Chef执行块(bash)运行时,它会自动失败。
bash 'install_dependencies' do
cwd '/opt/application/'
user 'app-user'
code <<-EOH
./scripts/install-deps.sh
EOH
end
有什么建议吗? 这是失败的输出:

您还可以使用poise-python
cookbook中的pip_requirements
资源,它可以为您完成所有这些工作。
看起来Chef的bash块没有为其所代表的用户设置主目录。 结果,pip无法找到/使用缓存目录。 在脚本中明确说明该问题已解决:
#!/bin/bash
source venv/bin/activate
pip install -v -r requirements.txt --cache-dir /home/app-user/.cache/pip >> scripts/scripts.out
