无法在Lighttable中评估Clojure

Question

我现在正在学习lighttable和clojure。但是我有一个问题，当我试图评估我的clojure脚本时，权限被拒绝了。

错误是这样的

We couldn't connect.

Looks like there was an issue trying to connect to the project. Here's what we got:

我知道这是关于权限的，但我不知道我应该更改哪个文件夹/文件的权限。我已经在所有的plugins文件夹中做了chown，我正在使用Manjaro中的Lighttable IDE

可能不是相同的潜在原因，因为你的错误似乎不在MacOS上，但同样的错误由于应用程序转移而出现。

在最新版本的MacIS上，有一个名为App Translocation的安全功能，可以在只读文件系统上运行应用程序(请参阅http://lapcatsoftware.com/articles/app-translocation.html和https://objective-see.com/blog/blog_0x15.html)。

Light Table权限错误将涉及路径/private/var/folders/.../AppTranslocation...

若要解决此问题，请将LightTable.app和灯光都放在/Applications文件夹中。对于它们中的每一个，都要通过允许未签名应用程序(http://www.macworld.com/article/3094865/macs/how-to-run-apps-that-are-not-from-the-app-store-in-macos-sierra.html)的流程。然后，不是启动LightTable.app，而是启动light (这也将启动一个控制台窗口)。

 Please check your access rights for /opt/LightTable/resources/app/plugins/Clojure/runner/resources/.nrepl-port

看起来它与LightTalbe中的clojure插件有关

强烈建议检查LightTable配置
