Appium automation test foundation - appium installation (I)

3、 ... and 、APPium install

We're going to use APPium The test framework , First you need to install APPium service ,Devices Represents the mobile phone we want to link ,Appium Client The client that wrote code for us （ That is, the test script , Download the corresponding language library according to the script language you need .）
（ One ）APPium server install
Mode one ：
Use Node.js Mode of installation APPium server service .

1、Node.js The download

Node.js Official download address ：https://nodejs.org/en/.

Select the installation method of the required functions .

Click the icon to change how features are installed .

explain ：

• Node.js runtime： install Node.js Operating environment .
• npm package manager： install npm Package manager , This is a Node Recommended package manager .
• online documentation shortcuts ： Add programs to the start menu , Include links Node.js and Node.js Online documentation of the website .
• Add to PATH： add to Node.js and npm The installation path to the environment variable .

（5） Install the tools required to compile native modules .

The prompt will automatically install 2 A tool ：

• Building tools (Python 2 and Visual Studio Building tools )
• Chocolatey

Build tools because of some npm Modules need to use C/C++ compile , If you want to compile these modules , You need to install this tool .
If you don't install this build tool , Use after npm When installing the module , Will report a mistake ：

gyp ERR! find Python

If you see this error , I know it's because it's not installed Building tools .
Build tools and Chocolatey It's a must , If not installed now , You can install it manually later , Relevant explanations have been given in the prompt ：https://github.com/nodejs/node-gyp#on-windows
The tip also tells you Chocolatey Will pop up in the back cmd To install .
To avoid future trouble , It is strongly recommended to choose “Automatically install ...” , then Next...

（6） Click on Install install Node.js.

（7） installation is complete , Click on finish.

3、Node.js Installation verification

We can go straight to CMD Anywhere in the command line window , Carry out orders node -v see Node.js edition .
the latest version Node.js At the time of installation, it also installed npm, perform npm -v see npm edition .

C:\Users\L>node -v v14.15.1  C:\Users\L>npm -v 6.14.8  

explain ：
test npm Is the installation successful , Thanks to the new edition of Node.js It's integrated npm, So before npm Also installed .
It can also be used cmd Command line input npm -v To test whether the installation was successful .
tips：
You can also get it from windows Enter... From the start menu of the system Node.js Command line terminal .

Tips ：
.msi Mode of installation Node.js After completion , Have already put node.exe Add to system environment variable path in . If you download .zip Format Node.js file , Because there is no installation process , So you need to manually node.exe Add the directory to the environment variable path in .

4、 To configure npm

To configure npm The path and cache when installing the global module cache The path of .
explain ：
Because of the installation Node.js In the process , Integrated installation of npm,npm Environment variables are automatically configured , If there is a specific need , You have to reconfigure .
Therefore, when performing, for example npm install -g appium When you command global installation , The module will be installed in by default C:\Users\ user name \AppData\Roaming The next path npm and npm_cache in , This is inconvenient to manage and occupies C Disk space , As shown in the figure below ：

So you need to configure npm Custom global module installation directory , stay Node.js Create two new folders under the installation directory node_global and node_cache, And then in cmd The following two commands are executed under the command ：
npm config set prefix "F:\DevInstall\nodejs\node_global"
npm config set cache "F:\DevInstall\nodejs\node_cache"
Create two directories ：

Carry out orders ：

C:\Users\L>npm config set prefix "F:\DevInstall\nodejs\node_global"
​
C:\Users\L>npm config set cache "F:\DevInstall\nodejs\node_cache"
​
C:\Users\L>

After configuration , These two custom Node.js The module installation directory has taken effect .

5、Appium server install

Get into CMD Execute directly in the command line window Appium server Installation command .
Here are two kinds of downloads ：

• Install the latest version Appium server：npm install -g appium
