python - 即使我能够安装其他库，安装 pyinstaller 时也会出现 SSL 错误

Question

我在一个公司环境中，我正在尝试为我的程序制作一个 .exe 文件。在这个企业环境中，我必须在安装库时使用代理。例如:

pip --proxy https://web-proxy.xxx.xxx.net:8080 install pyinstaller

我能够安装除 pyinstaller 之外的所有其他库

我什至尝试在另一个跳转站上安装该库(您仍然必须在其中使用公司代理)，但我仍然无法安装。这是完整的回溯(请记住，我的公司仍在使用 python 2.7):

我在安装任何其他库时都没有得到那个回溯，只有这个。我想我必须回家并在那里安装它？

Answer 1

不清楚您要安装到哪个 Python 版本。在我的设置中，我还有一个 python2.7，它在我安装 pyinstaller 库时被调用。我在我的虚拟环境中使用 Python3.4(.venv)

你必须去你想安装pyinstaller的特定环境。例如

(.ven) C:\Python\Development>C:\Python\Development\.venv\Scripts\python -m pip install pyinstaller

这将从指定的环境中调用 python 并执行用于安装库的 pip 模块。
