无法安装julia软件包

我今天刚刚安装了julia，并尝试添加图像包，但它不起作用。直到100%为止，它都能抓取。然后，它会在抓取过程中保持大约4分钟，不会发生类似的情况：

(@v1.4) pkg> add Images
    Cloning default registries into `C:\Users\Quinten Cabo\.julia`
    Cloning registry from "https://github.com/JuliaRegistries/General.git"
    Fetching: [========================================>]  100.0 %

4分钟后，我发现这个错误：

    Cloning default registries into `C:\Users\Quinten Cabo\.julia`
    Cloning registry from "https://github.com/JuliaRegistries/General.git"

有人知道我应该在这里做什么才能安装软件包吗？

Windows有时似乎在克隆注册表时遇到问题。您可以尝试删除

C:\Users\Quinten Cabo\.julia\registries\General

并重试，或者（也许更好）您可以简单地

git克隆

julia之外的注册表到该位置

---

---

在即将发布的Julia 1.5版本中，注册中心默认情况下不会使用git，因此希望这个问题不会出现。

我删除了.Julia\registries\General，然后重新安装了该软件包，它成功了。因此，它再次建立了注册表

---

重建需要一点时间。要有耐心。

可能还有Windows？我们收到一些报告，其中Windows似乎随机删除了这些文件夹中的内容，例如缺少文件夹A-F。。不知道该怎么办，但如果删除文件夹并重新安装，它似乎通常是固定的。有一些计划的功能，以自动修复像这样的东西。是的，Windows。是的，通过删除注册表/常规和执行]更新来修复
