Fixing hb Installation Issues

What should I do if garbled characters and segmentation faults occur during hb installation?

Symptom Garbled characters and segmentation faults occur during the execution of the python3 -m pip install --user ohos-build command.
Possible Causes pip is of an early version.
Solution Upgrade pip.
```
python3 -m pip install -U pip
```

Symptom The message "cannot import 'sysconfig' from 'distutils'" is displayed during the execution of the python3 -m pip install --user ohos-build command.
Possible Causes The distutils module is unavailable.

Solution Install distutils.

sudo apt-get install python3.8-distutils

Symptom The message "module 'platform' has no attribute 'linux_distribution'" is displayed during the execution of the python3 -m pip install --user ohos-build command.
Possible Causes There is a compatibility issue of python3-pip.

Solution Reinstall pip.

sudo apt remove python3-pip
curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
python get-pip.py

Symptom The message "Could not find a version that satisfies the requirement ohos-build" is displayed during the execution of the python3 -m pip install --user ohos-build command.
Possible Causes The installation fails due to poor network connectivity.
Solution
1. Ensure that your computer has a good network connection. If the network connection is unstable, rectify the network fault and reinstall hb.
2. If the network is functional, run the following commands to install hb by specifying a temporary PyPI source:
```
python3 -m pip install -i https://pypi.tuna.tsinghua.edu.cn/simple ohos-build
```
