ubuntu安裝最新的mercurial

Mercurial 是一種輕量級分布式版本控制系統，采用 Python 語言實現，易於學習和使用，擴展性強

之前安裝的mercurial版本(2.8.2)太老了，想安裝最新版本的。

網上搜到方法

sudo add-apt-repository ppa:tortoisehg-ppa/releases
sudo add-apt-repository ppa:mercurial-ppa/releases
sudo apt-get update
sudo apt-get install mercurial python-nautilus tortoisehg

但是提示更新失敗

W: Failed to fetch http://ppa.launchpad.net/mercurial-ppa/releases/ubuntu/dists/trusty/main/binary-amd64/Packages  Hash Sum mismatch
W: Failed to fetch http://ppa.launchpad.net/tortoisehg-ppa/releases/ubuntu/dists/trusty/main/binary-amd64/Packages  Hash Sum mismatch

關於Hash Sum mismatch,就不在這里討論了。

后來發現: pypi上有對應的安裝包

https://pypi.python.org/pypi/Mercurial

只要

sudo pip install mercurial -U #如果之前已安裝
sudo pip install mercurial    #如果之前未安裝

效果:

[hupeng@hupeng-vm ~]$hg --version
Mercurial Distributed SCM (version 4.1.3)
(see https://mercurial-scm.org for more information)
