尝试使用 pip 安装包时，“=”不是有效的运算符

Question

我正在尝试从 .txt 文件安装一些软件包。当我尝试安装它们时，pip 正在读取文件但说 '=' is an invalid operator。我也尝试将 '=' 更改为 '==' 但没有成功。

例如，我正在尝试安装 aniso8601=8.0.0=py_0，但一直出现错误：

ERROR: Invalid requirement: 'aniso8601=8.0.0=py_0' (from line 4 of requirements.txt)
Hint: = is not a valid operator. Did you mean == ?

Edit: I was getting the list of dependencies from someone else and the py_0 portion was an oversight by me as it was something added that they left on the end of their list.

Answer 1

我不确定你为什么放 =py_0 以及它的含义，但这是正确要求文件的示例：

Jinja2==2.10.1
qtawesome==0.7.2
numpy==1.18.3
matplotlib==3.2.2

要安装所有依赖项，请使用 pip install -r filename.txt

要创建需求文件，请使用 pip freeze > filename.txt
