問題1：Python版本問題

報錯信息：

NOTICE: You are using Python 3.6 which is EOL. Starting with v0.62.0, Meson will require Python 3.7 or newer

ubuntu 18默認的python3是3.6.

解決方案1：從源碼安裝python 3.7

wget https://www.python.org/ftp/python/3.7.4/Python-3.7.4.tgz

tar -xzvf Python-3.7.4.tgz

cd Python-3.7.4

./configure --prefix=/usr/local/src/python37? # 配置安裝位置

sudo make

sudo make install

?解決方案2：安裝python 3.7(推薦)

sudo apt install python3.7

sudo rm -rf? /usr/bin/python3

sudo ln -s? /usr/bin/python3.7?/usr/bin/python3

---

?pip3 install ninja 失敗找不到ninja

更新python源：

1. 切換到根目錄下

   $?cd?~

2. 新建.pip目錄并進入

   $?mkdir?.pip
   $?cd?.pip

3. 新建pip.conf文件并用vim打開

   $?touch?pip.conf
   $?vim?pip.conf

4. 將以下寫入

[global]index-url?=?https://artsz.zte.com.cn/artifactory/api/pypi/public-pypi-virtual/simple[install]trusted-host=artsz.zte.com.cn

5. 重新安裝

sudo apt-get install python3-pip

sudo pip3?install meson

sudo pip3?install ninja
