Question

我正在运行Manjaro Linux 18.0.4。我似乎不小心卸载了一些Ruby gem，或者通过执行 ctrl + c 中断了安装。

我尝试使用以下方法卸载所有gems：

gem uninstall -aIx

并弹出错误代码：

ERROR:  While executing gem ... (NameError)
    uninitialized constant Gem::RDoc

我还尝试通过pamac卸载Ruby本身。

我想重新开始。最好的方法是什么？

var idHttp : TIdHTTPEx; url : string; slTemp : TStringList; memoryStream : TMemoryStream; begin idHttp := TIdHTTPEx.Create(nil); // parent class is TIdHTTP, inherited to be able to execute HTTPS slTemp := TStringList.Create; memoryStream := TStringStream.Create; try idHttp.Request.ContentType := 'application/json'; url := 'https://safebrowsing.googleapis.com/v4/threatMatches:find?key=' + GOOGLE_SAFE_BROWSING_API_KEY + ' HTTP/1.1'; slTemp.Text := '{"client":{"clientId":"iGame","clientVersion":"1.0.0"},"threatInfo":{"threatTypes":"MALWARE","platformTypes":"WINDOWS","threatEntryTypes":"URL","threatEntries":[{"url":"http://www.hyxyg.com/default.php"},{"url":"https://jsonlint.com/"}]}}'; idHttp.Post(url, slTemp, memoryStream); memo1.Text := memoryStream.ToString; finally memoryStream.Free; slTemp.Free; idHttp.Free; end; end;是我完全想重新开始时要遵循的内容。因此，类似于var idHttp : TIdHTTPEx; // parent class is TIdHTTP, inherited to be able to execute HTTPS url : string; requestBody : TStream; sTemp : string; begin url := 'https://safebrowsing.googleapis.com/v4/threatMatches:find?key=' + GOOGLE_SAFE_BROWSING_API_KEY + ' HTTP/1.1'; //url := 'https://httpbin.org/post'; idHttp := TIdHTTPEx.Create(nil); requestBody := nil; try idHttp.Request.Accept := 'application/json'; idHttp.Request.ContentType := 'application/json'; sTemp := '{"client":{"clientId":"iGame","clientVersion":"1.0.0"},"threatInfo":{"threatTypes":"MALWARE","platformTypes":"WINDOWS","threatEntryTypes":"URL","threatEntries":[{"url":"http://www.hyxyg.com/default.php"},{"url":"https://jsonlint.com/"}]}}'; //sTemp := '{"日本語":42}'; requestBody := TStringStream.Create(sTemp, TEncoding.UTF8); sTemp := idHttp.Post(url, requestBody); memo1.Text := sTemp + sLineBreak + sLineBreak + idHttp.ResponseText; finally requestBody.Free; idHttp.Free; end; end;

注意：sudo apt-get purge <packages>也将删除其配置文件。

我总是建议人们使用sudo apt-get purge ruby rubygems

安装ruby
