【问题描述】：

您好，我一直在尝试使用 chaquopy 来运行我的 python 脚本，但我在导入部分遇到了麻烦。当我运行不需要任何外部库且不使用您将在 build.gradle 中编写的安装代码的脚本时，它工作正常。

        python
            pip
                install "numpy"
            
        

我一插入安装代码，问题就出现了。它出现了下面写的错误消息。

pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.

我认为 SSLError 发生在其他人身上，但我找不到 SyntaxWarning: 'str' object ~~ 是关于什么的。

【问题讨论】：

SyntaxWarning 是由旧版本的 pip (github.com/pypa/pip/issues/7615) 引起的：我们将在下一版本的 Chaquopy 中修复此问题。

【参考方案1】：

问题本身不在 pip install 命令中。 真正的问题来自使用 anaconda 中的 python.exe 而不是原始的 python.exe。 下载 python 3.8.6 并更改 buildpython 路径后，我能够解决问题。

【讨论】：

你是如何使用 buildpython 的？它对我不起作用:::: python buildPython "C:/Program Files/Python39" pip install "numpy"

@ParthaPaul: buildPython 应该是实际 python 可执行文件的路径，而不是包含它的目录。
