第一步，找到目录

这里每个人的电脑不同，目录也不同。教你万能的方法，你可以打开C盘搜索 “AppData”，直接查看“微信开发者工具”目录，找最新升级日期，找到里面的WeappLocalData打开它就对了。这是我电脑的目录：

C:\Users\xxx\AppData\Local\微信开发者工具\User Data\5614c56fc9c154dbeba624c6e66e9224\WeappLocalData

仅供参考，这里的xxx是电脑用户名称，根据个人电脑管理员不同显示不同。

第二步，创建文件

进入WeappLocalData目录后创建文件。网上很多说快捷方式调出设置，都黑屏了，还没打开工具呢，怎么调？

创建文件localstorage_b72da75d79277d2f5f9c30c9177be57e.json，粘贴下面的内容保存即可。（如果已经有该文件，替换里面的内容，原文件可复制一份防止该方法不适于你）。

{"show":false,"currentCategory":"proxy","compiler":{"clusterCompile":false,"autoPreview":false,"autoRemoteDebug":false},"general":{"openLastModifiedProject":true,"autoPreviewType":"mobile","autoRemoteDebugType":"mobile","maxLogLength":300,"enableNewFW":true,"enableGPU":false,"ignoreUnsafeProxy":false,"defaultWorkspace":"D:\\WeChatProjects","locale":"zh"},"appearance":{"theme":"dark","devtoolsTheme":"dark","fontFamily":"SF Mono","fontSize":12,"lineHeight":20,"simulatorAlignment":"left"},"edit":{"tabSize":2,"insertSpaces":true,"wrap":"on","minimap":false,"gitIgnoreWindowsReturn":true,"autoTypingsDetectEnabled":true,"alwaysOpenFileInNewTab":false,"autoSave":false,"autoRefresh":false,"saveBeforeCompile":false,"saveBeforePreview":false,"saveBeforeUpload":false},"proxy":{"proxyType":"SYSTEM","proxyHost":"127.0.0.1","proxyPort":"12639"},"notification":{"bbs":true,"sys":true,"alarm":true},"security":{"enableServicePort":true,"port":30150},"geo":{"enabled":false,"latitude":39.92,"longitude":116.46,"speed":-1,"accuracy":65,"altitude":0,"verticalAccuracy":65,"horizontalAccuracy":65},"shortcuts":{"_editingShortcuts":false,"toggleToolbar":{"modifiers":["cmd","shift"],"key":"T"},"toggleSimulatorWindow":{"modifiers":["cmd","alt"],"key":"S"},"toggleEditorWindow":{"modifiers":["cmd","shift"],"key":"E"},"toggleFileTree":{"modifiers":["cmd","shift"],"key":"M"},"toggleDebugWindow":{"key":"I","modifiers":["cmd","shift"]},"rebuild":{"key":"B","modifiers":["cmd"]},"format":{"key":"F","modifiers":["shift","alt"]},"refresh":{"key":"R","modifiers":["cmd"]},"toggleForegroundBackgroundStatus":{"key":"","modifiers":[]},"documentationSearch":{"key":"","modifiers":[]},"gotoFile":{"key":"P","modifiers":["cmd"]},"gotoRecentFile":{"key":"E","modifiers":["cmd"]},"preview":{"key":"P","modifiers":["shift","cmd"]},"upload":{"key":"U","modifiers":["shift","cmd"]}},"syncTime":1584263702017}

我的解决的,就是黑屏的时候,再次点击开发者工具,再次启动,不行的话 隔10秒左右再点开发者工具,我的黑屏就是 重复的重启开发者工具,注意是黑屏的时候,黑屏也不要关 ,重复点击开发者工具,会突然一下就好了

win7的用户，可以试试安装最新版的vc++, 我这边就是这样解决的。
