I use package who need some package
prompt-toolkit == 0.54
another package need
prompt-toolkit == 0.46
when I upgrade prompt-toolkit to 0.54, another package not work properly
how I deal with it
您需要的是virtualenv模块 。
我认为这对pip无效,但是您可以将这些软件包的不同版本复制到site-packages /中(例如package_v1
和package_v2
),并将其作为import package_v1 as package
代码中。
