Failed to activate conda environment

问题描述

Pycharm Terminal显示以下错误，导致无法自动激活当前项目的conda环境

原因分析

查看log文件，发现真实的错误是找不到conda的路径

2024-07-25 10:35:24,316 [1553431]   INFO - #c.j.p.packaging - System conda executable is not found
2024-07-25 10:35:24,316 [1553431]   WARN - #c.i.p.t.PyVirtualEnvTerminalCustomizer - Can't find null, will not activate conda

查看github上文件对应的源代码：python/python-sdk/src/com/jetbrains/python/packaging/CondaExecutablesLocator.kt
可以发现它默认是从sdk path去找conda的可执行文件，但是由于我这里环境修改了env_dirs的存储目录，使其跟conda的安装路径不一致了，所以它找不到conda的可执行文件。
之后则去环境变量、用户的home目录找conda的可执行文件，windows是conda.bat，但是window是装在用户home目录下的AppData\Local文件夹的，所以这里找不到。

@JvmStatic
fun getCondaExecutable(sdkPath: String?): @SystemDependent String? {
  if (sdkPath != null) {
val condaPath = findCondaExecutableRelativeToEnv(Path.of(sdkPath))
if (condaPath != null) {
  LOG.info("Using $condaPath as a conda executable for $sdkPath (found as a relative to the env)")
  return condaPath.toString()
}
  }

  val preferredCondaPath = getInstance().preferredCondaPath
  if (!preferredCondaPath.isNullOrEmpty()) {
val forSdkPath = if (sdkPath == null) "" else " for $sdkPath"
LOG.info("Using $preferredCondaPath as a conda executable$forSdkPath (specified as a preferred conda path)")
return preferredCondaPath
  }

  return getSystemCondaExecutable()?.toString()
}

private const val CONDA_BAT_NAME = "conda.bat"
fun getSystemCondaExecutable(): Path? {
  val condaName = if (SystemInfo.isWindows) CONDA_BAT_NAME else CONDA_BINARY_NAME

  // TODO we need another findInPath() that works with Path-s
  val condaInPath = PathEnvironmentVariableUtil.findInPath(condaName)
  if (condaInPath != null) {
    LOG.info("Using $condaInPath as a conda executable (found in PATH)")
    return condaInPath.toPath()
  }

  val condaInRoots = getCondaExecutableByName(condaName)
  if (condaInRoots != null) {
    LOG.info("Using $condaInRoots as a conda executable (found by visiting possible conda roots)")
    return condaInRoots
  }

  LOG.info("System conda executable is not found")
  return null
}

解决方案

PATH环境变量中添加condabin的路径：C:\Users\xxx\AppData\Local\miniconda3\condabin
