How to Install Zlib on Ubuntu Linux
|
||||
======
|
||||
|
||||
[Zlib][1] is an open source library for used for data compression.
|
||||
|
||||
As an end user, you are likely to encounter the need of installing Zlib (or zlib devel package) as a dependency of another application.
|
||||
|
||||
But here comes the problem. If you try installing Zlib on Ubuntu, it will throw “unable to locate package zlib” error.
|
||||
|
||||
```
|
||||
sudo apt install zlib
|
||||
Reading package lists... Done
|
||||
Building dependency tree
|
||||
Reading state information... Done
|
||||
E: Unable to locate package zlib
|
||||
```
|
||||
|
||||
Why do you see this [unable to locate package error][2]? Because there is no package named zlib.
|
||||
|
||||
If you [use the apt search command][3], you’ll find that the there are a couple of packages that let you install zlib: **zlib1g and zlib1g-dev**. When you have that information, installing them is just one apt command away.
|
||||
|
||||
### Install Zlib on Ubuntu-based Linux distributions
|
||||
|
||||
Open a terminal and use the following command:
|
||||
|
||||
```
|
||||
sudo apt install zlib1g
|
||||
```
|
||||
|
||||
_**Please keep in mind that the the letter before g is 1 (one), not lowercase L. Many people make this mistake while typing the command.**_
|
||||
|
||||
The other package, zlib1g-dev is development package. Only install it if you require it otherwise you should be good with the main runtime zlib1g package.
|
||||
|
||||
```
|
||||
sudo apt install zlib1g-dev
|
||||
```
|
||||
|
||||
You may also download the source code of Zlib [from its website][1] and install it. However, I won’t recommend going the source code way just for installing zlib unless you have a good reason to do so. For example, if you need the latest or a specific version of zlib which is not available in the distribution’s repository.
|
||||
|
||||
It is interesting how a seemingly small stuff like installing zlib could become a pain for two reasons: a different package name and the package name containing a “hidden” numeral one (1) which is confused with lowercase L.
|
||||
|
||||
I hope this quick tip helps you. Feel free to drop your questions, suggestions or a simple “thank you” in the comment section.

如何在 Ubuntu Linux 上安装 Zlib
|
||||
======
|
||||
|
||||
[Zlib][1] 是一个用于数据压缩的开源库。
|
||||
|
||||
作为使用者，你可能会遇到需要将 Zlib（或 zlib devel 包）作为另一个应用程序的依赖项的情况。
|
||||
|
||||
但问题来了，如果你尝试在 Ubuntu 上安装 Zlib，它会抛出 “unable to locate package zlib” 错误。
|
||||
|
||||
```bash
|
||||
sudo apt install zlib
|
||||
Reading package lists... Done
|
||||
Building dependency tree
|
||||
Reading state information... Done
|
||||
E: Unable to locate package zlib
|
||||
```
|
||||
|
||||
为什么会看到这个 [Ubable to locate package 错误][2]呢？因为没有名为 zlib 的包。
|
||||
|
||||
如果你 [使用 apt search 命令][3]，你会发现有几个包可以让你安装：**zlib 1g 和 zlib 1g-dev**。当你知道这些后，只需一个 apt 命令就可以安装它们。
|
||||
|
||||
### 在基于 Ubuntu 的 Linux 发行版上安装 Zlib
|
||||
|
||||
打开终端，使用以下命令：
|
||||
|
||||
```bash
|
||||
sudo apt install zlib1g
|
||||
```
|
||||
|
||||
_**请记住 g 前面的字母是 1(一)，而不是小写的 L。很多人在输入命令时都会犯这个错误。**_
|
||||
|
||||
另一个包，zlib 1g-dev 是开发包。只有在你需要时才安装它，否则你应该使用 zlib 1g 包。
|
||||
|
||||
```bash
|
||||
sudo apt install zlib1g-dev
|
||||
```
|
||||
|
||||
你也可以[ Zlib 网站][1]下载源代码并安装它。但是，除非你有充分的理由，否则我不推荐使用源代码方式来安装 zlib。例如，如果你需要最新或特定版本的 zlib，但该版本在发行版的仓库中不可用。
|
||||
|
||||
有趣的是，像安装 zlib 这样看似很小的东西可能会变得很麻烦，有两个原因：一个是不同的包名；另一个是包含“隐藏”数字 1，它与小写 L 混淆了。
|
||||
|
||||
我希望这个快速提示能帮助到你。随意在评论部分留下你的问题、建议或简单的一句 “thank you”。
