1、Python使用requirements.txt安裝類庫 出現錯誤

pip install -r requirements.txt

“No such file or directory: ‘requirements.txt’”
解決辦法：cd 到這個檔案下，再執行命令。
2、出現以下錯誤：
Could not find a version that satisfies the requirement pkg-resources=0.0.0 (from -r requirements.txt (line 2)) (from versions: ) No matching distribution found for pkg-resources==0.0.0 (from -r requirements.txt (line 2))
解決辦法： 刪除txt檔案中對應的內容即可
