# paddlejs prepare 主要流程
# 1. 判断 node, npm 是否安装
# 2. 下载测试模型，当前检测模型是 ch_PP-OCRv2_det_infer ，识别模型是 ch_PP-OCRv2_rec_infer [1, 3, 32, 320]。如果需要替换模型，可直接将模型文件放在test_tipc/web/models/目录下。
#  - 文本检测模型：https://paddleocr.bj.bcebos.com/PP-OCRv2/chinese/ch_PP-OCRv2_det_infer.tar
#  - 文本识别模型：https://paddleocr.bj.bcebos.com/PP-OCRv2/chinese/ch_PP-OCRv2_rec_infer.tar
#  - 文本识别模型[1, 3, 32, 320]：https://paddlejs.bj.bcebos.com/models/ch_PP-OCRv2_rec_infer.tar
#  - 保证较为准确的识别效果，需要将文本识别模型导出为输入shape[1, 3, 32, 320]的静态模型
# 3. 转换模型， model.pdmodel model.pdiparams 转换为 model.json chunk.dat（检测模型保存地址：test_tipc/web/models/ch_PP-OCRv2/det，识别模型保存地址：test_tipc/web/models/ch_PP-OCRv2/rec）
# 4. 安装最新版本 ocr sdk  @paddlejs-models/ocr@latest
# 5. 安装测试环境依赖 puppeteer、jest、jest-puppeteer，如果检查到已经安装，则不会进行二次安装

# 判断是否安装了node
if ! type node >/dev/null 2>&1; then
