如何修复“错误：找不到与安装匹配的版本”？

Question

我正在尝试使用 pipenv 安装 django-crispy-forms。

它安装是因为当我运行“pip freeze”命令时我看到了它。

什么时候锁定 [包] 依赖项……

它面临锁定，我收到此错误。

[pipenv.exceptions.ResolutionFailure]: Warning: Your dependencies could 
not be resolved. You likely have a mismatch in your sub-dependencies.
First try clearing your dependency cache with $ pipenv lock --clear, then 
try the original command again.  Alternatively, you can use $ pipenv 
install --skip-lock to bypass this mechanism, then run $ pipenv graph to 
inspect the situation.
Hint: try $ pipenv lock --pre if it is a pre-release dependency.ERROR: 
ERROR: Could not find a version that matches install
No versions found
Was https://pypi.org/simple reachable?

我尝试运行以下命令建议 [pipenv install --skip-lock 和 pipenv install --skip-lock] 但我仍然遇到相同的错误。

这怎么解决，因为我想在 Heroku 上部署项目，但我不知道这是否会阻止项目部署？

尝试从 pipfile 中删除给您带来问题的库，检查您是否有拼写错误。

pipenv install "any-library" 会将 "any-library" 插入到 pipfile 中，即使它不存在，这可能是错误的原因之一，

示例： $ pipenv install any-library

错误：错误：找不到与任何库匹配的版本
