fpm 对python3.7.5虚拟环境进行打包

python3.7.5环境打包

打包前准备环境

可能是由于版本原因，fpm打包时默认会从系统拿默认的python来打包，即使进行虚拟环境也一样。但是我们需要用python3。
所以首先把系统默认的python改为3.7

cp /usr/bin/python3.7 /usr/bin/python
cp /usr/bin/pip3.7 /usr/bin/pip3.7

因为打包virtualenv需要virtual-tools==1.0，但是1.0的virtual-tools在python3中并不兼容。

pkg_resources.DistributionNotFound: The 'virtual-tools==1.0' distribution was not found and is required by the application

所以先用pip3.7安装virtual-tools3

pip install virtualenv-tools3

然后拷贝执行文件到目录备份

cp /usr/local/python37/lib/python3.7/site-packages/virtualenv_tools.py ~

再重新装virtual-tools==1.0

pip uninstall virtualenv-tools3
pip install virtualenv-tools==1.0

拷贝脚本覆盖

cp ~/virtualenv_tools.py /usr/local/python37/lib/python3.7/site-packages/virtualenv_tools.py

这样子就可以打包了
