已知版本扭曲 python

Question

我想检查我的 OS 上安装了哪个版本的 twisted python。我需要 17.1.0 或更高版本，并且我在 CentOS 7.

上工作

我试过这个：

(.synapse)[root@nexus-chat1 .synapse]# twisted -v
  -bash: twisted : commande introuvable

但是我该如何升级我的版本呢？如果我这样做，它会更新吗？

(.synapse)[root@nexus-chat1 .synapse]# pip install twisted

Answer 1

使用：

pip search twisted

在输出中您应该看到所需的信息：

Twisted (17.9.0)                     - An asynchronous networking framework written in Python
  INSTALLED: 16.3.0
  LATEST:    17.9.0

更新到最新可用版本：

pip install --upgrade twisted

Answer 2

如果安装了twisted，可以写pip show twisted
