FileNotFoundError： [Errno 2] 没有这样的文件或目录： b'/Users//<myname>Desktop/kivy/kivy-ios/dist/hostpyt

Question

因为我在Xcode中构建项目时得到了这个错误，

ModuleNotFoundError: No module named 'requests'

，然后我试图安装请求模块与git命令。

python toolchain.py pip install requests

然而，我读了日志，我得到了这个FileNotFoundError消息。我该如何处理这个错误?

所以我查看了文件"/Users//Desktop/kivy/kivy-ios/dist/hostpython3/bin/pip3"和虚拟环境文件"/Users//Desktop/kivy/kivy-ios//lib/python3.9/site-packages/sh.py"看看它们是否存在。而且它们都是真实存在的!我被这个错误弄糊涂了。所以请帮帮我吧!这是我运行我的第一个应用程序的最后一步!谢谢!

Answer 1

让我们分步骤解决这个问题:

我假设您的toolchain.py文件是您想要运行的脚本，您需要requests模块。

步骤1:激活虚拟环境(您可能已经这样做了)

在使用pip install <module>安装一个新模块之前，你想激活你的虚拟环境，因为你想在那里安装它。

你可以这样做:

• linux:source <your-venv-path>/bin/activate
• 在windows:<your-venv-path>Scriptsactivate.bat

关于如何激活虚拟环境的一些很好的答案可以在Windows和Linux中找到。

步骤2:安装请求模块

现在您的虚拟环境是活动的，您应该能够像这样安装请求模块:

pip install requests

步骤3:运行脚本

在此之后，您应该能够像这样运行安装了请求模块的脚本:

python toolchain.py

Answer 2

在过去的几天里，我尝试了很多方法来解决这个问题，但都失败了。最后，kivy discord里的一个管理员帮我解决了这个问题。

在我的例子中，也许我使用命令sudo toolchain.py build python kivy。然而，sudo是坏的，可能是导致这个问题的原因。

在我清理构建并使用toolchain.py build python kivy重新安装所有kivy后，我终于解决了这个问题。感谢管理员和kivy社区的帮助!
