除python之外的Conda更新包

我是python的初学者，我正在使用anaconda的旧版本，它有python的3.5.2版本，因为我想使用tensorflow。我有一些过时的软件包，我想用“conda update all”更新。有没有一种方法可以在不将python从3.5更新到3.6的情况下实现这一点，因为这与tensorflow不兼容？

您可以手动将它们全部更新

conda update yourpackage

…或者您可以全部更新它们

conda update--all

，然后使用

conda install python=3.5.2

简短回答再次降级python

conda update--all--dry run 2>/dev/null|
grep-Fe'-->'|
切割-d''-f3|
grep-ve'python'|
xargs conda更新

---

长话短说 步骤1：试运行以检查要更新的包 命令

conda update--all--dry run

结果
