如何從需求中使用pip安裝許多軟件包

Question

如果我這樣安裝軟件包：

pip install selenium

然后我可以看到帶有yolk -l的軟件包

如果我使用pip install -r requirements.txt軟件包，則在未安裝所有消息和克隆軟件包之后，就不會出現在yolk -l

這些包去哪兒了？

Answer 1

嘗試使用pip install -r requirements.txt安裝軟件包，然后先運行pip freeze 。 程序包應顯示在此處。 如果不是，則說明它們安裝不正確。 如果它們出現在凍結輸出中，則運行yolk -l應該得到相同的結果。

Answer 2

看起來在您的requirements.txt文件中安裝期間，其中很少有軟件包有錯誤。 如果其中之一發生故障，那么什么也不會安裝。

我也發生了這件事。 只需從文件中刪除該軟件包，一切正常
