Use python3 to install third on ubuntu
- Problem discovery
Use jenkins to manage my python code, because the python3.5 version is used, first use virtualenv on ubuntu to generate a python3.5 virtual operating environment
virtualenv -p /usr/bin/python3.5 --no-site-packages python3.5
The virtualenv command is to create an "independent" runtime environment for python, because when there are multiple versions of our system, and when 2 and 3 are completely incompatible, at this time we need an independent for each version Operating environment
Let's check what's in this directory
This contains our complete python operating environment, and then the python variable and pip variable are defined on jenkins
Then we created a job. In this job, we use git to pull our code. The code address is on github. After the pull is completed, we set the shell operation to be executed in our custom Execute shell. Prompt that the library psutil needs to be installed, so in the system
pip install psutil
Show that the installation is successful, and then rebuild, through the console output, it is still prompted that there is no psutil library
Second, the problem conjecture
- I guess that this may be the successful installation on python2. It reads the path from the python2 library, and the pip used is also version 2, so I use the ××× of this package to unzip, and use python3 in the virtual environment .5
python3.5 setup.py build
The result shows that the x86_64-linux-gnu-gcc command does not exist, but this command does exist in the system, so I suspect that the virtualenv environment may not be common to the outside environment
- Using the python3.5 installation that comes with the system, it still shows that the x86_64-linux-gnu-gcc command does not exist. Checking through the jenkins console output window shows that a file in psutil does not have the header file Python.h, and Baidu shows python The development kit does not exist, and finally found the answer to the question.
Three, solve the problem
Because python3 is used in the file, the development package of python3 should be used, so install his development package
sudo apt-get install python3-dev
sudo apt-get upgrade
Then use in the psutil package
python3.5 setup.py build
python3.5 setup.py install
Solve the problem completely.
