virtualbox增加新硬盘的方法

在virtualbox中装好Ubuntu后，发现硬盘空间太小，怎样才能增加硬盘容量？那就是再建一个硬盘：

  1. 添加新硬盘

    设置 -> Storage -> SATA控制器->右击，选择“添加虚拟硬盘”

    然后，根据需求创建合适的硬盘

  2. 重启虚拟机

查看现有系统的磁盘空间

sibosend / MANIFEST.in
Created April 2, 2020 02:02 — forked from jpmens/MANIFEST.in
Including git version in setup.py files. (Requires at least _one_ tag in the repo) Normally used to make things like, "python setup.py sdist" give you a predictable name for files. Normally used with tags on the repo like 0.1 or 2.3.0 You should add RELEASE-VERSION to MANIFEST.in so that end users of the tarball can use this too.
include RELEASE-VERSION
include version.py
# Anything else you normally use
