CouchDB 服务在安装后无法正确启动
CouchDB service does not startup correctly after installation
我已经在 Windows 7 Pro 笔记本电脑上安装了 CouchDB (v2.2.0)。我已经安装到默认的 C:\CouchDB 位置。安装不报错
然而，当我尝试导航到 localhost:5984 以验证我的安装时，我收到了一个站点无法访问的错误。
我试过卸载、重启和重新安装都无济于事。
我希望其他人也有同样的经历并找到了解决方案。我在 couchdb 网站上找不到任何指导。以下是我的 couch.log 文件的摘录：

特此回答我自己的问题：
问题似乎与 MySQL 5.6 安装有关。
我怀疑这两个应用程序存在冲突，因为一旦我安装了 couchDB，我就会在 MySQL 服务中报告偶尔的错误。
我卸载了 MySQL 并重新安装了 couch db，它现在可以正常运行了。我会再次尝试安装 MySQL，看看是否会再次发生这种情况。
目前，此问题已解决。
我在 windows 8.1 for couchdb-2.2.0 中遇到了类似的错误，在尝试了以下答案中提到的几个步骤后我开始工作了。
虽然好像和Mysql有关系，但是我没有卸载mysql。我认为它无法正确解析 windows 样式路径变量条目（有空格）。
- 替换nssm.exe
- 从 cmd（管理员）启动 couchdb
- 第一次失败，erl.exe崩溃，会提示加入防火墙例外，允许
- 运行 couchdb.cmd 又成功了。
Starting CouchDB from cmd
您只需从 PATH 变量中删除 MySQL 个条目。不需要卸载 MSQL。
