如何使用 CLI 恢复 NuGet 包？
How do I restore a NuGet package using the CLI?
我正在尝试使用 CLI 在我的项目中恢复 NuGet 包。我正在使用的命令如下所示：
NuGet.exe 恢复 [解决方案文件] -ConfigFile [配置文件] -NoCache
[解决方案文件] 是我的 .sln 文件的路径
[Config file] 是我解决方案的.nuget 文件夹中 NuGet.Config 文件的路径
当我 运行 这个命令时，我总是得到“无法找到包的 版本。”任何更新的包都会发生这种情况。
在同一台机器上，我可以在 Visual Studio 中打开解决方案，它会很好地更新包。 Visual Studio 设置为使用来源：https://api.nuget.org/v3/index.json，这是报告为从 CLI 使用的相同提要。无法弄清楚为什么它可以从 VS 而不是 CLI。
更新：
我原来的 nuget.config 看起来像这样：
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<solution>
<add key="disableSourceControlIntegration" value="true" />
</solution>
<packageSources>
<add key="nuget.org" value="https://api.nuget.org/v3/index.json" protocolVersion="3" />
</packageSources>
</configuration>
我根据Perry的回答修改成这个。我用更新的配置得到了相同的结果：
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<config>
</config>
<packageSources>
<add key="nuget.org" value="https://api.nuget.org/v3/index.json" protocolVersion="3" />

已将 NuGet.exe 更新到版本 5.8.0 并将 Verbosity 设置为 Detailed 并得到以下结果：

我使用的是 VS 2019，所以我不确定是否需要指定它。我假设问题与“无法创建 SSL/TLS 安全通道”消息有关，但我不确定如何解决该问题。
首先，您应该仔细检查您的 nuget.config 文件。
这是 nuget.config 文件的正确格式：
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<config>
</config>
<packageSources>
<add key="public feed" value="https://api.nuget.org/v3/index.json"/>

然后，使用命令nuget restore xxx\ConsoleApp38.sln -ConfigFile "xxx\ConsoleApp38\.nuget\nuget.config" -NoCache，就可以了
一开始，我在<config></config>下写了任何其他节点，这会导致与您所说的相同的错误，如下所示：

之后，我发现<config></config>和<packageSources></packageSources>的水平一样。
您应该按照 this official document 编写您的 nuget.config 文件。
此外，如果您没有找到您的nuget.config文件，您可以与我们分享，让我们找出问题所在。另外，您可以使用*替换隐私信息。

还有，因为你的nuget.exe太旧了，旧的可能会有一些问题。您应该使用我已经成功测试过的最新 nuget.exe v5.8.0。所以请从 this link.
