搜索了类似的问题后，我认为这可能是依赖问题，但是，在使用“Yarn”安装依赖项后，我仍然遇到同样的问题。 使用“纱线构建”在本地构建效果很好。

Answer 1

在尝试将我的单页React JS Web 应用程序部署到 Netlify 时，我发现了同样的错误。

以下是我解决问题并成功部署站点的过程。

1. 转到站点设置。

   

2. 从菜单中选择构建和部署下拉菜单。

3. 从下拉列表中选择持续部署选项卡。

4. 在Build Settings部分下，选择Edit settings 。

   • 将构建命令更改为CI= npm run build
   • 单击保存。

   

5. 然后从下拉列表中选择环境选项卡。

   • 选择编辑变量。
   • 作为Key输入CI ，作为value输入false 。
   • 单击保存。

   

6. 最后再次重试部署站点。

这将帮助您解决与在 Netlify 中托管“Rect JS”应用程序相关的问题，并且您的应用程序将成功部署。

Answer 2

您必须更改环境变量值才能成功构建。 请按照以下步骤操作：

• 转到Deploy settings 。
• 单击Environment ，然后单击Edit Variables按钮。
• 将Key设置为CI并将Value设置为false 。
• 现在点击Save按钮。

现在您可以构建和部署您的项目而不会出现错误。

Answer 3

弄清楚了。 它是 app.js 的外壳，我只需要将其更改为 App.js，

Answer 4

我也遇到了同样的错误，但是使用此命令 CI= npm run build 清除了我的错误，但是我又遇到了同样的错误，然后尝试了这个，但这次它不起作用，但我通过以下方法解决了这个问题：

• 检查您推送的代码是否存在（github，bitbucket..whatever）
• 如果部署失败尝试恢复推送并使用 CI= npm run build 重试，如果失败也创建另一个（新提交推送）部署
• 在我的情况下，它在执行上述程序后失败了 5 次，它运行良好

Answer 5

我收到此错误是因为我有一个编译错误，但我不知道，因为未暂存的本地更改将它隐藏在我的本地环境中。

就我而言， newFile.js尚未提交。 但是newFile.js被导入到了committedFile.js中。 由于newFile.js没有提交，构建无法编译，没有文件可导入到committedFile.js中。

执行此操作以查看是否有隐藏的编译错误：

使用git stash -u本地未提交的更改，看看是否在本地出现编译错误。

Answer 6

请按照以下确切步骤操作，因为我遇到了同样的问题，直到我按照说明执行此操作：

1. Go 到站点设置>构建和部署>持续部署。
2. Go 到Build Settings > Edit Settings 。
3. 将您的构建命令编辑为CI= npm run build （查看npm run build和=之间的空格。拥有它非常重要）。
4. 在发布目录中写入build 。
5. Go 到Environment > Edit Variables 。
6. 您必须在Key中写入变量CI并在Value中写入false 。
7. 点击保存。
8. Go部署并在第二部分中，单击触发部署和 select 清除缓存并部署站点。

这将解决错误，现在您可以部署您的站点。 享受！
