## h2 Change Linux shell to bash.
Run the following command on the terminal to check whether the shell is bash:
```
ls -l /bin/sh
```
如果为显示为/bin/sh -\> bash则为正常，否则请按以下方式修改：
**方法一**
在终端运行如下命令，然后选择 no。
```
sudo dpkg-reconfigure dash
```
**方法二**
Delete sh and run sh again.
```
rm -rf /bin/sh
sudo ln -s /bin/bash /bin/sh
```
## Installing the Python environment
1. Open the terminal of the Linux compilation server.
2. Run the **python3 --version** command to check the Python version. Python 3.7 or later is required. Otherwise, perform the following steps \(Python 3.8 is used as an example\):
- If the Ubuntu version is 18, run the sudo apt-get install python3.8 command.
- If the Ubuntu version is 16, download the installation package and install Python.
1. Run the following command to install the python dependency:
Run sudo apt-get install gcc to install gcc.
Install g++ and run sudo apt-get install g++.
Run the sudo apt-get install make command to install make.
Run the sudo apt-get install zlib\* command to install zlib.
Install libffi and run "sudo apt-get install libffi-dev".
2. Obtaining the python3.8.5 Installation Package
3. Run the **tar -xvzf Python-3.8.5.tgz** command.
4. Run the **cd Python-3.8.5** command.
5. Run the **sudo ./configure** command.
6. Run the **make** command.
7. Run the **sudo make install** command.
- Run the sudo apt-get install python3-setuptools python3-pip -y command to install the Python package management tool. \(The root/sudo permission is required for the installation.\) Upgrade pip3 and run "sudo pip3 install --upgrade pip".
Alternatively, install the Python package management tool as instructed by the official website. Download "curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py" and run python get-pip.py.
3. Install **setuptools** by running the **pip3 install setuptools** command.
4. Install GUI menuconfig by running the **sudo pip3 install kconfiglib** command. The Kconfiglib 13.2.0+ version is recommended. \(The root/sudo permission is required.\)
You can also perform the following steps to install Kconfiglib 13.2.0+:
1. Download the .whl file \(for example, kconfiglib-13.2.0-py2.py3-none-any.whl\).
Download path: https://pypi.org/project/kconfiglib\#files
1. Install the .whl file by running the **sudo pip3 install kconfiglib-xxx.whl** command \(for example, **sudo pip3 install kconfiglib-13.2.0-py2.py3-none-any.whl**\). \(The root/sudo permission is required.\)
2. If an error of **subprocess.CalledProcessError: Command '\('lsb\_release', '-a'\)' returned non-zero exit status 1.** occurs, run the **find / -name lsb\_release** command, for example, **rm -rf /usr/bin/lsb\_release** to locate **sb\_release** and release it.
## Installing **gn**
1. Open a Linux terminal.
2. Download [gn](https://chrome-infra-packages.appspot.com/dl/gn/gn/linux-amd64/+/latest).
3. Decompress the tool package to the **\~/gn** directory on the Linux server.
4. Set environment variables by running the **vim /etc/profile** command and add new variables by running the **export PATH=\~/gn:$PATH** command.
5. Validate environment variables by running the **source /etc/profile** command.
## Installing **ninjah**
1. Open a Linux terminal.
2. Download [ninja](https://github.com/ninja-build/ninja/releases/download/v1.10.0/ninja-linux.zip).
3. Decompress the tool package to the **\~/ninja** directory on the Linux server.
4. Set environment variables by running the **vim /etc/profile** command and add new variables by running the **PATH=\~/ninja:$PATH** command.
5. Validate environment variables by running the **source /etc/profile** command.
## Installing the LLVM tool chain
1. Open a Linux terminal.
2. Download [http://tools.harmonyos.com/mirrors/clang/9.0.0-33042/linux/llvm-linux-9.0.0-33042.tar](http://tools.harmonyos.com/mirrors/clang/9.0.0-33042/linux/llvm-linux-9.0.0-33042.tar).
3. Decompress the tool package to the **\~/llvm** directory on the Linux server.
4. Set environment variables by adding **export PATH=\~/bin:$PATH** to the **vim /etc/profile** profile.
5. Validate environment variables by running the **source /etc/profile** command.
## Installing File Packing Tools
1. Open a Linux terminal.
2. Run the **mkfs.vfat** command. If the command is not found, run the **sudo apt-get install dosfstools** command.
3. Run the **mcopy** command. If the command is not found, run the **sudo apt-get install mtools** command.
