如何让jenkins运行"pip install"？

Question

我有一个git repo,想让jenkins克隆它然后运行

virtualenv venv --distribute
/bin/bash venv/source/activate
pip install -r requirements.txt
python tests.py

jenkins的控制台输出是:

+ virtualenv venv --distribute
New python executable in venv/bin/python
Installing distribute..........................done.
Installing pip...............done.
+ /bin/bash venv/bin/activate
+ pip install -r requirements.txt
Downloading/unpacking flask (from -r requirements.txt (line 1))
  Running setup.py egg_info for package flask

SNIP

creating /usr/local/lib/python2.7/dist-packages/flask

error: could not create '/usr/local/lib/python2.7/dist-packages/flask': Permission denied

----------------------------------------
Command /usr/bin/python -c "import setuptools;__file__='/var/lib/jenkins/workspace/infatics-website/build/flask/setup.py';exec(compile(open(__file__).read().replace('\r\n', '\n'), __file__, 'exec'))" install --single-version-externally-managed --record /tmp/pip-hkdBAi-record/install-record.txt failed with error code 1
Storing complete log in /home/jenkins/.pip/pip.log
Build step 'Execute shell' marked build as failure
Finished: FAILURE

我尝试在命令之前添加sudo,但它也不起作用:

+ sudo pip install -r requirements.txt
sudo: no tty present and no askpass program specified
Sorry, try again.
sudo: no tty present and no askpass program specified
Sorry, try again.
sudo: no tty present and no askpass program specified
Sorry, try again.
sudo: 3 incorrect password attempts
Build step 'Execute shell' marked build as failure
Finished: FAILURE

任何想法如何解决这个问题？此外,当我在终端中运行pip install -r requirement.txt作为jenkins用户时,它不需要sudo权限.我可以让jenkins(流程)作为jenkins用户运行吗？

您必须运行use sudo来运行这一事实pip是一个很大的警告,表明您的虚拟环境无法运行.构建输出显示pip正在系统site-packages目录中安装需求,这不是virtualenv的工作方式.

您的构建脚本实际上不会保留激活的虚拟环境.activate脚本设置的环境变量在子bash进程中设置,不会传播到构建脚本.您应该使用activate脚本而不是运行单独的shell:

virtualenv venv --distribute
. venv/bin/activate 
pip install -r requirements.txt
python tests.py

如果你将它作为一个构建步骤运行,那应该可以工作(并在venv中安装你的软件包).如果要添加更多步骤,则需要在其他步骤中设置PATH环境变量.您可能最好提供完整路径pip并python确保您不依赖于系统包安装.
