已解析的依赖项中存在不兼容的版本

Question

我\xe2\x80\x99m 试图运行我的python 项目，该项目似乎在我的Mac 上运行良好（在pycharm 中最好，不太好，但可以在VSCode 中运行），但在VSCode 中的树莓派上运行得很糟糕。每当我运行 apipenv shell然后运行 ​​a 时，pipenv install它都会抱怨以下错误：

我不\xe2\x80\x99t 在运行pipenv graph(after pipenv install --skip-lock) 后看到什么\xe2\x80\x99s 不兼容，因为它返回：

似乎每个版本都在版本范围内正确安装，包括它抱怨的 graphene-django [必需：>=3.0.0b1，已安装：3.0.0b7]。

\n

为什么会发生这个错误？

pip3 list返回：

我\xe2\x80\x99已经尝试了很多方法来尝试解决这个问题，但不知道从这里该去哪里。我想在我的树莓派上部署这个 python、graphql 和 React 项目，但我假设我可以 \xe2\x80\x99t 如果我可以 \xe2\x80\x99t 甚至让它运行。我正在尝试在我的树莓派（运行 raspbian）上运行它，问题出在后端 python 应用程序上。

\n

任何帮助，任何事情都将非常感激。我\xe2\x80\x99m是Python的初学者。

Answer 1

您以某种方式设法安装了测试版（使用--pre flag before then deleted the option from Pipfile, for example or used pip directly in the virtual env).

\n

现在，由于django-graphql-jwt不符合语义版本控制，他们决定依赖主要版本，在补丁版本中预发布\xc2\xaf\\_(\xe3\x83\x84)_/\xc2\xaf\n.

\n

由于 0.3.1 版本django-graphql-jtw依赖于>=2.5.1，您的测试版仍然会匹配，但没有--pre flag locking will fail, because the highest non-beta version is 2.5.1. That is the conflict being shown (but the output isn\'t very clear).

\n

The resolution that should solve the issue is:

\n

pipenv uninstall django-graphql-jwt django-graphene graphene graphql\n# followed by:\npipenv install \'django-graphql-jwt<0.3.2\'\n
